POLYMER TANTALUM CHIP CAPACITORS

COMPONENT PERFORMANCE CHARACTERISTICS

Introduction

4. Voltage Ratings

KEMET has developed a new type of tantalum capacitor

that replaces the solid manganese dioxide electrode with

a solid conductive polymer. This product is named the

KO-CAP for KEMET Organic Capacitor. The basic fami-

lies are the T520 and T530 series. A separate detail of

performance characteristics is presented here as there

are some differences between the polymer tantalums and

the standard MnO2 types. Like all KEMET tantalum

chips, these series are 100% screened for all electrical

parameters: Capacitance @ 120 Hz, Dissipation Factor

(DF) @ 120 Hz, ESR @ 100 kHZ and DC Leakage. It is

also 100% surge current tested at full rated voltage

through a low impedance circuit. The advantages of the

polymer include very low ESR and elimination of the

potentially catastrophic failure mode that may occur with

standard tantalum capacitors in a high surge current

application. Although the natural KO-CAP series failure

mechanism is a short circuit, it does not exhibit an explo-

sive failure mode.

• 2V-16V DC Rated Voltage

This is the maximum peak DC operating voltage

from -55ºC to +85ºC for continuous duty. Above

85ºC, this voltage is derated linearly to 0.8 times

the rated voltage for operation at 105ºC.

• Surge Voltage Ratings

Surge voltage is the maximum voltage to which the

part can be subjected under transient conditions

including the sum of peak AC ripple, DC bias and

any transients. Surge voltage capability is demon-

strated by application of 1000 cycles of the relevant

voltage, at 25ºC, 85ºC or 105ºC. The parts are

charged through a 33 ohm resistor for 30 seconds

and then discharged through a 33 ohm resistor for

30 seconds for each cycle.

5. Reverse Voltage Rating & Polarity

Polymer tantalum capacitors are polar devices and

may be permanently damaged or destroyed if con-

nected in the wrong polarity. The positive terminal

is identified by a laser-marked stripe and may also

include a beveled edge. These capacitors will with-

stand a small degree of transient voltage reversal

for short periods as shown in the following table.

Please note that these parts may not be operated

continuously in reverse, even within these limits.

3. Capacitance and Tolerance

• 33µF to 1500µF

• ±20% Tolerance

Capacitance is measured at 120 Hz, up to 1.0 volt rms

maximum and up to 2.5V DC maximum. DC bias caus-

es only a small reduction in capacitance, up to about

2% when full rated voltage is applied. DC bias is not

commonly used for room temperature measurements

but is more commonly used when measuring at tem-

perature extremes.

Capacitance does decrease with increasing frequency,

but not nearly as much or as quickly as standard tanta-

lums. Figure 1 compares the frequency induced cap roll-

off between the KO-CAP and traditional MnO2 types.

Capacitance also increases with increasing tempera-

ture. See s ection 12 for temperature coefficients .

6. DC Leakage Current

Because of the high conductivity of the polymer,

the KO-CAP family has higher leakage currents

than traditional MnO2 type Tantalum caps. The DC

Leakage limits at 25ºC are calculated as 0.1 x C x

V, where C is cap in µF and V is rated voltage in

Volts. Limits for all part numbers are listed in the

ratings tables.

ture. The limits for 85ºC @ Rated Voltage and

9. Equivalent Series Resistance (ESR) and

Impedance (Z)

105ºC @ 0.8 x Rated Voltage are both 10 times

the 25ºC limit.

The Equivalent Series Resistance (ESR) of the KO-

CAP is much lower than standard Tantalum caps

because the polymer cathode has much higher

conductivity. ESR is not a pure resistance, and it

decreases with increasing frequency.

7. Surge Current Capability

Certain applications may induce heavy surge cur-

rents when circuit impedance is very low (<0.1

ohm per volt). Driving inductance may also cause

voltage ringing. Surge currents may appear as

transients during turn-on of equipment.

Total impedance of the capacitor is the vector

sum of capacitive reactance (X ) and ESR, below

C

resonance; above resonance total impedance is

the vector sum of inductive reactance (X_L) and

The KO-CAP has a very high tolerance for surge

current. And although the failure mechanism is a

short circuit, they do not explode as may occur

with standard tantalums in such applications.

The KO-CAP series receives 100% screening for

Capacitors are surged 4 times at full rated voltage

applied through a total circuit resistance of <0.5

ohms. Failures are removed during subsequent

electrical testing.

Dissipation factor is measured at 120 Hz, up to 1.0

volt rms maximum, and up to 2.5 volts DC maxi-

mum at +25ºC. The application of DC bias causes

a small reduction in DF, about 0.2% when full

ra te d vo lta g e is a p p lie d . DF inc re a s e s with

Dissipation factor is the ratio of the equivalent

series resistance (ESR) to the capacitive reac-

tance, (X ) and is usually expressed as a percent-

C

age. It is directly proportional to both capacitance

and frequency. Dissipation factor loses its impor-

tance at higher frequencies, (above about 1 kHz),

where impedance (Z) and equivalent series resis-

tance (ESR) are the normal parameters of concern.

10. AC Power Dissipation

Power dissipation is a function of capacitor size

and materials. Maximum power ratings have been

established for all case sizes to prevent overheat-

ing. In actual use, the capacitor’s ability to dissi-

pate the heat generated at any given power level

may be affected by a variety of circuit factors.

These include board density, pad size, heat sinks

and air circulation.

L — Repres ents lead wire and cons truction

inductance. In mos t ins tances (es pecially in

solid tantalum and monolithic ceramic capaci-

tors) it is insignificant at the basic measurement

frequencies of 120 and 1000 Hz.

tance in series with the capacitance. Lead wires

R_d— The dielectric loss contributed by dielectric

becomes very significant in high frequency mea-

surements and applications. Its value varies with

frequency.

C_d— The inherent dielectric absorption of the

solid tantalum capacitor which typically equates

to 1-2% of the applied voltage.

11. AC Operation

As fre q ue nc y inc re a s e s , X_Cc o ntinue s to

decrease according to its equation above. There

is unavoidable inductance as well as resistance

in all capacitors, and at some point in frequency,

the re a c ta nc e c e a s e s to b e c a p a c itive a nd

becomes inductive. This frequency is called the

self-resonant point. In solid tantalum capacitors,

the resonance is damped by the ESR, and a

s mooth, rather than abrupt, trans ition from

capacitive to inductive reactance follows.

Permissible AC ripple voltage and current are

related to equivalent series resistance (ESR) and

power dissipation capability.

Permis s ible AC ripple voltage which may be

applied is limited by three criteria:

a. The positive peak AC voltage plus the DC bias

voltage, if any, must not exceed the DC voltage

rating of the capacitor.

Figure 4 compares the frequency response of a

KO-CAP to a standard Tantalum chip. See also

frequency curves shown in the T520 section,

p.39. Maximum limits for 100 kHz ESR are listed

in the part number tables for each series.

b. The negative peak AC voltage, in combination

with bias voltage, if any, must not exceed the

permissible reverse voltage ratings presented

in Section 5.

c. The power dissipated in the ESR of the capaci-

tor mus t not exceed the appropriate value

specified in Section 10.

Frequency Comparisions are located on page

43. Maximum limits for 100 kHz are listed in the

part number table on page 42.

20. Failure Mechanism and Reliability

13. Standard Life Test

The normal failure mechanism is dielectric break-

down. Dielectric failure can res ult in high DC

Leakage current and may proceed to the level of a

short circuit. With sufficient time to charge, heal-

ing may occur by one of two potential mecha-

nisms. The polymer adjacent to the dielectric fault

site may overheat and vaporize, disconnecting the

fault site from the circuit. The polymer may also

the defect site in the dielectric and reduces the

flow of current.

Post Test Performance:

Capacitor failure may be induced by exceeding

the ra te d c ond itions of forwa rd DC volta ge ,

tion or temperature. Exces s ive environmental

stress, such as prolonged or high temperature

reflow processes may also trigger dielectric failure.

Post Test Performance:

d. ESR - within initial limit

Failure rates may be improved in application by

derating the voltage applied to the capacitor.

KEMET recommends that KO-CAPs be derated

to 80% or less of the rated voltage in application.

KO-CAPs exhibit a benign failure mode in that

they do not fail catastophically even under typical

fault conditions. If a shorted capacitor is allowed

to pass unlimited current, it may overheat and the

case may discolor. But this is distinctly different

from the explosive “ignition” that may occur with

standard MnO2 cathode tantalums. Replacement

of the MnO2 by the polymer removes the oxygen

that fuels ignition during a failure event.

components is recommended to avoid extreme

thermal s tres s . The maximum recommended

29. Handling

Automatic handling of encapsulated components

is enhanced by the molded case which provides

compatibility with all types of high speed pick and

p la c e e q uip me nt. Ma nua l ha nd ling of the s e

should be taken with your fingers, however, to

avoid touching the solder-coated terminations as

body oils, acids and salts will degrade the sol-

derability of thes e terminations . Finger cots

should be used whenever manually handling all

solderable surfaces.

Hand-soldering should be avoided. If necessary,

it should be performed with care due to the diffi-

culty in process control. Care should be taken to

avoid contact of the soldering iron to the molded

case. The iron should be used to heat the solder

pad, applying solder between the pad and the

termination, until reflow occurs. The iron should

be removed. “Wiping” the edges of a chip and

heating the top surface is not recommended.

30. Termination Coating

During typical reflow operations a slight darken-

ing of the gold-colored epoxy may be observed.

This slight darkening is normal and is not harmful

to the product. Marking permanency is not affect-

ed by this change.

The standard finish coating is 90/10 Sn/Pb solder

(Tin/Lead-solder coated). 100% tin coating is

available upon request.

31. Recommended Mounting Pad Geometries

Proper mounting pad geometries are essential for

successful solder connections. These dimensions

designed to maximize the intergrity of the solder

joint, and to minimize component rework due to

unacceptable solder joints.

33. Washing

Standard washing techniques and solvents are

compatible with all KEMET surface mount tanta-

lum capacitors. Solvents such as Freon TMC and

TMS, Trichlorethane, methylene chloride, prelete,

and isopropyl alcohol are not harmful to these

components. Please note that we are not endors-

ing the use of banned or restricted solvents. We

are simply stating that they would not be harmful

to the components.

intended to be a starting point for circuit board

designers, to be fine tuned, if necessary, based

upon the peculiarities of the soldering process

and/or circuit board design.

If ultrasonic agitation is utilized in the cleaning

process, care should be taken to minimize energy

levels and exposure times to avoid damage to the

terminations.

35. Storage Environment

Courtyard

Tantalum chip capacitors should be stored in nor-

mal working environments. While the chips them-

selves are quite robust in other environments,

solderability will be degraded by exposure to high

temperatures, high humidity, corrosive atmos-

pheres, and long term storage. In addition, pack-

aging materials will be degraded by high temper-

ature - reels may soften or warp, and tape peel

force may increase. KEMET recommends that

maximum storage temperature not exceed 40

degrees C, and the maximum storage humidity

not exceed 60% relative humidity. In addition,

temperature fluctuations should be minimized to

avoid condensation on the parts, and atmos-

pheres should be free of chlorine and sulfur bear-

ing compounds. For optimized solderability, chip

stock should be used promptly, preferably within

1.5 years of receipt.
