GR500 HIGH RELIABILITY SOLID TANTALUM

Introduction

+125°C prior to the electrical testing which eliminates

those capacitors failing to withstand this extreme

change in environment.

2. Surge Current — Each GR500 capacitor receives

10 cycles @ -55°C, + 85°C. Each cycle consists of rated

voltage charge for 4 1 seconds and a discharge for 4 1

seconds. Total DC resistance (excluding the test capac-

itor) is ≤1.0 ohms. The energy storage bank capacitor(s)

is 100,000 F minimum.

The solid tantalum capacitor has become an essential device

in circuits requiring high capacitance-voltage product and

extended environmental capability. The KEMET GR500

Graded Reliability concept has made available state-of-the-

art devices providing maximum assurance of meeting sys-

tem reliability goals. All Graded Reliability capacitors

receive meticulous attention from raw material selection

through manufacture, final inspection and shipping. Having

survived a very stringent quality control program, the result-

ing capacitors meet or exceed the most critical requirements

of space, satellite, missile and medical applications where

failure is, at best, expensive, and at worst, fatal.

3. Grading — This term is used to describe the tech-

nique which defines the failure rate of KEMET Graded

Reliability capacitors. Grading consists of placing

GR500 capacitors in an oven at 85°C for a minimum of

250 hours at a voltage greater than rated voltage. The

technique is fundamentally based upon the oft-docu-

mented fact that solid tantalum capacitors do not con-

form to the exponential distribution of time-ordered fail-

ures, but instead exhibit a constantly decreasing failure

rate. The Weibull distribution provides a valuable tool

for describing the behavior of solid tantalum capacitors,

and experimental fits are made to this distribution in

determining performance levels for each GR500 Series

batch. Actual test data are provided with each shipment

of capacitors to document the failure rate obtained.

4. Electrical Testing — Each GR500 Series capacitor

is tested at 25°C for leakage current at rated voltage, as

well as capacitance and dissipation factor at 120 Hz.

Since uniformity is generally a valid indicator of relia-

bility, parametric distributions are graphically recorded

for each lot. Parts which deviate from the normal popu-

lation are discarded. Guaranteed maximum values are

as detailed in Table 1.

KEMET is, therefore, committed to the principle of the

highest possible reliability in the manufacture and grading of

its GR500 Series capacitors.

The KEMET GR500 High Reliability concept disallows

grouping of diverse ratings and production batches to deter-

mine average failure rates. Instead, data from each and every

capacitor batch are statistically fitted to determine failure

rate on the basis of 100% life testing. Each homogeneous

production batch is “gradedʼʼ as a single inspection lot, and

documented evidence of failure rate achieved is supplied

with the parts, providing assurance of the most sophisticated

and accurate reliability measurement method in the industry.

Basic Requirements

A. Manufacturing Environment — It is of vital impor-

tance that high reliability electronic components be manu-

factured in an environment which provides commitment to

the philosophy of high reliability production. GR500 Series

capacitors are manufactured in a plant area that stresses this

philosophy. Manufacturing and quality control personnel

are selected for experience and competence. Extensive

training in quality and reliability assurance techniques is

provided, and motivation of personnel is heavily stressed.

Raw material and in-process inspection techniques are

especially rigid. The result is a capacitor product of inher-

ently superior quality.

5. ESR — Each GR500 capacitor is tested for ESR @

100 KHz. See electrical specification tables.

6. X-ray — Each GR500 Series capacitor is examined

by X-ray in two planes with 90 degree rotation. Since

assembly of the solid tantalum capacitor is a blind oper-

ation, optical inspection cannot reveal internal defects

such as loose solder balls or deficient anode solder

bonding.

B. Screening Test — All GR500 Series capacitors are sub-

jected to a broad test program. Despite the most rigid of

quality control procedures, some variation among batches of

capacitors must be recognized. This fact is understandable

when one considers the inherent differences which derive

from the 16 to 1 ratio of operating voltages, the 20 to 1 ratio

of physical sizes, and the 60,000 to 1 ratio among capaci-

tance ratings. Maximum assurance of reliability is achieved

by maintaining batch identity from the raw material with

respect to capacitor sizes and ratings as well as material

identification. Each batch is then subjected to extensive,

non-destructive 100% screening tests as indicated below.

1. Thermal Shock — Inherent variations exist among

the temperature coefficients of expansion of the various

materials required in the manufacture of solid tantalum

capacitors. In worst-case combinations, individual

capacitors will exhibit sensitivity to temperature excur-

sions. Consequently, all GR500 Series capacitors

undergo ten temperature cycles between -65°C and

7. Hermeticity — Each GR500 capacitor receives her-

meticity testing per MIL-STD-202, Method 112,

Condition D. This test uses a fluorocarbon liquid at

125°C 5°(257°F 9°F) at ambient pressure and detects

gross leaks by the observation of bubbles.

C. Sampling — In addition to the 100% screening tests,

other tests are imposed on a sample basis to determine para-

metric stability and resistance to environmental extremes.

These tests are fully described in the GR500 Graded

Reliability Specification.

D. Available Special Testing — In addition to the standard

testing outlined in this catalog, optional testing is available.

1. 100% ESR testing at various frequencies

2. 1 KHz DF

3. Tightened DC leakage, Capacitance and Dissipation

Factor limits.

APPLICATIONS INFORMATION GR500/T210

Introduction — The following section is provided for assis-

tance in the application of T210 Series capacitors. Space

does not permit a complete discussion of all technical

aspects, and further information on specific problems may

be obtained through KEMET sales representatives.

The capacitance of solid tantalum capacitors decreases

with frequency as shown in Figure 1. The nominal values of

DC Leakage Current — The DC Leakage current limits of

Table I are the lowest generally specified in the solid tanta-

lum industry. Even lower leakage currents are available on

special order. Low leakage current, aside from its intrinsic

value, is an indication of anode quality. DC leakage current

as a function of temperature is represented by the typical

curve in Figure 4, while similar information pertaining to

leakage behavior with respect to voltage is contained in

Figure 5.

APPLICATIONS INFORMATION GR500/T210 (Continued)

Expected reliability factors for voltages and temperatures

other than the rated conditions may be found in Figure 6.

Since T210 Series capacitors are supplied with a predeter-

mined failure rate under rated conditions, reliability under

use conditions may be estimated with this nomograph.

Circuit Impedance — Failure rates are affected by temper-

ature and voltage as described in Figure 6 and also by the

circuit impedance seen by the capacitor. Originally, applica-

tion advice for solid tantalum capacitors suggested an

impedance of 3 ohms or higher per applied volt. This advice

was later found to be unnecessarily conservative, and the

factors below are based on 0.1 ohm per volt as the unity fail-

ure rate multiplier.

Voltage and Temperature Ratings; Reliability Effect —

T210 Series capacitors are manufactured in 6 through 100

volt ratings at 85ºC. Operation at 125ºC with 2/3 rated volt-

age applied gives equivalent results and voltage may be der-

ated linearly between these two points. Solid tantalum

capacitors may be operated continuously at any voltage from

zero to the maximum rating without adverse effects.

Operation at voltage below nameplate improves reliability,

while subsequent operation at a higher voltage will not be

affected by prior low voltage use.

Equivalent Series Resistance — The equivalent series

resistance (ESR) of a solid tantalum capacitor is frequency

dependent as shown in Figure 7a thru 7g. The curves are typ-

ical of the capacitor values noted, with measurements being

made by contacting lead wires /4 inch from the ends of the

capacitor cases. Since ESR decreases with frequency, AC

performance at higher frequencies is considerably better

than would be predicted from the 120 Hz ratings.

Capacitor Impedance — The relationship between imped-

ance and frequency at various voltage ratings is illustrated

with typical curves in Figure 7. Impedance declines with

decreasing capacitive reactance, but ESR becomes dominant

before the self-resonant point is reached, producing the typ-

ical damped curves. Finally, impedance increases as induc-

tance of the lead wire and other capacitor elements domi-

nates. Obviously, high frequency impedance is directly

influenced by the length of lead wire and general mounting

AC Ripple — Permissable AC ripple voltage is related to

the rated voltage, the ESR of the capacitor, and the power

dissipation capability of a particular case size:

3. The power dissipated in the equivalent series

resistance of the capacitor must not exceed the

limits specified in Table II.

Reverse Voltage — The solid tantalum capacitor is basically

a polar device and can be damaged by serious reversals of

polarity even for short periods of time, depending upon the

circuit impedance. However, some short duration reversal is

permissable as shown in Table III.

The power dissipated may be calculated from the

following:

E²R

Z²

P =

Where E = ripple voltage across capacitor in rms volts

Z = capacitor impedance in ohms at the specified fre-

quency (typical values from Figure 7)

Ripple voltage, as limited by power dissipation, may be

determined as follows:

Shelf Life — Shelf life is particularly difficult to define for

the solid tantalum capacitor. Extended periods of storage at

high temperature will cause some small change in leakage

current which usually returns to normal upon short time

application of working voltage. Storage at low temperatures

causes little or no degradation of leakage current. Long-term

studies of capacitance and dissipation factor shift for as long

as 45,000 hours indicate only minor variations (usually less

than 2%) in these parameters.

Installation — Mounting procedures should not place

undue strain on terminals, particularly the positive end with

its glass-metal seal. Attention to soldering technique should

avoid excessive heat transfer which might remelt the capac-

itorʼs internal solder and cause loss of hermeticity or short

circuits. Potting materials should not produce excessive cur-

ing exotherms or shrinkage pressures.

E max (25C) = Z

Where P max=maximum permissible power from

Table III

R = ESR from Figure 7

E max (85C) = 0.9 E max (25C)

E max (125C) = 0.4 E max (25C)

APPLICATIONS INFORMATION GR500/T240

Introduction — The following section is devoted to general

information of assistance in the application of T240 Series

capacitors. Space does not permit a complete discussion of

all technical aspects, and further information on specific

problems may be obtained through KEMET sales represen-

tatives.

shown in Figure 2. Dissipation factor loses its importance as

a measurement parameter at higher frequencies, where

impedance and ESR are the normal parameters of concern.

Capacitance — The nominal values listed in Table I con-

forms to accepted industry practice; intermediate values may

be produced on special order. Standard tolerances are

20%, 10%, and 5%. Closer tolerances may be pro-

duced upon special order and after agreement upon mea-

surement conditions.

Typical variation of capacitance with respect to tempera-

ture is illustrated in Figure 1a. The capacitance of solid tan-

talum capacitors decreases with frequency, as shown in

Figure 1b.

DC Leakage Current — The DC Leakage current limits of

Table 1 for T240 Series capacitors are the lowest generally

specified in the solid tantalum industry. Even lower leakage

currents are available on special order. Low leakage current,

aside from its intrinsic value, is an indication of anode qual-

ity. DC leakage current as a function of temperature is rep-

resented by the typical curve in Figure 3, while similar infor-

mation pertaining to leakage behavior with respect to volt-

age is contained in Figure 4.

Voltage and Temperature Ratings; Reliability Effect —

T240 Series capacitors are manufactured in 6 through 60

volt ratings at 85°C. Operation at 125°C with 2/3 rated volt-

age applied gives equivalent results, and voltage may be der-

ated linearly between these two points. Unlike wet elec-

trolytic capacitors, solid tantalum capacitors may be oper-

ated continuously at any voltage from zero to the maximum

rating without adverse effects. Operation at voltage below

nameplate improves reliability, while subsequent operation

at a higher voltage will not be affected by prior low voltage

use.

Expected reliability factors for voltages and temperatures

other than the rated conditions may be found in Figure 5.

Since T240 Series capacitors are supplied with a predeter-

mined failure rate under rated conditions, reliability under

use conditions may be estimated with this nomograph.

Circuit Impedance — Failure rates are affected by temper-

ature and voltage as described in Figure 5 and also by the

circuit impedance seen by the capacitor. Traditionally, appli-

cation advice for solid tantalum capacitors suggested an

impedance of 3 ohms or higher per applied volt. This advice

was later found to be unnecessarily conservative, and the

factors in Table II, are based on 0.1 ohm per volt as the unity

failure rate multiplier.

Capacitor Impedance — The relationship between imped-

with typical curves in Figure 6. Impedance declines with

decreasing capacitive reactance, but ESR becomes dominant

before the self-resonant point is reached, producing the typ-

ical damped curves. Finally, impedance increases as induc-

tance of the lead wire and other capacitor elements domi-

nates. Obviously, high frequency impedance is directly

Reverse Voltage — The solid tantalum capacitor is a polar

device and can be damaged by serious reversals of polarity

even for short periods of time. However, some short duration

reversal is permissable as shown in Table IV.

AC Ripple — Permissable AC ripple voltage is related to

the rated voltage, the ESR of the capacitor, and the power

dissipation capability of a particular case size:

1. The positive peak AC voltage plus the DC bias

voltage (if any), must not exceed the rated voltage.

2. The negative peak AC voltage, in combination

with the bias voltage (if any), must not exceed that

allowable (see Reverse Voltage).

Surge Current — Surge current testing is performed to pro-

vide resistance from damage due to circuit transients. This

test, employing total DC circuit resistance of 1.0 max, exclu-

sive of the capacitor, is described on Page 21.

Shelf Life — Shelf life is particularly difficult to define for

the solid tantalum capacitor. Extended periods of storage at

high temperature will cause some small change in leakage

current which usually returns to normal upon short time

application of working voltage. Storage at low temperatures

causes little or no degradation of leakage current. Long-term

studies of capacitance and dissipation factor shift for as long

as 45,000 hours indicate only minor variations (usually less

than 2%) in these parameters.

3. The power dissipated in the equivalent series

resistance of the capacitor must not exceed the

limits specified in Table III.

The power dissipated may be calculated from the

following:

P =

Z

Where E = ripple voltage across capacitor in rms volts

Z = capacitor impedance in ohms at the specified

frequency.

R = equivalent series resistance in ohms

Installation — Mounting procedures should not place

undue strain on terminals, particularly the positive end with

its glass-metal seal. Attention to soldering technique should

avoid excessive heat transfer which might remelt the capac-

itorʼs internal solder and cause loss of hermeticity or short

circuits. Potting materials should not produce excessive cur-

ing exotherms or shrinkage pressures.

Ripple voltage, as limited by power dissipation, may be

determined as follows:
