Snap-In Aluminum Electrolytic Capacitors

PEH526 Series, 125ºC

Overview

Applications

KEMET's PEH526 is an electrolytic capacitor with outstanding

electrical performance. The device is polarized, has a negative

pole connected to the case and a plastic cover for the outer case.

Low ESR is the result of a low resistive electrolyte/paper system.

Together with the TDC thermal concept, this range gives the

PEH526 a very high ripple current capability. It is suitable for

use in both mobile and aircraft applications with operation up to

+125°C.

KEMET's PEH526 is a high performance electrolytic capacitor

designed for automotive applications with high vibrations and

high ambient temperatures.

Shelf Life

The capacitance, ESR and impedance of a capacitor will not change signiﬁcantly after extended storage periods, however the leakage

current will very slowly increase. KEMET products are particularly stable and allow a shelf life in excess of three years at 40°C. See

sectional speciﬁcation under each product series for speciﬁc data.

Re-age (Reforming) Procedure

Apply the rated voltage to the capacitor at room temperature for a period of one hour, or until the leakage current has fallen to a steady

value below the speciﬁed limit. During re-aging a maximum charging current of twice the speciﬁed leakage current or 5 mA (whichever

is greater) is suggested.

Reliability

The reliability of a component can be deﬁned as the probability that it will perform satisfactorily under a given set of conditions for a

given length of time.

In practice, it is impossible to predict with absolute certainty how any individual component will perform; thus, we must utilize probability

theory. It is also necessary to clearly deﬁne the level of stress involved (e.g. operating voltage, ripple current, temperature and time).

Finally, the meaning of satisfactory performance must be deﬁned by specifying a set of conditions which determine the end of life of the

component.

Reliability as a function of time, R(t), is normally expressed as: R(t)=e-^λt

where R(t) is the probability that the component will perform satisfactorily for time t, and λ is the failure rate.

Failure Rate

The failure rate is the number of components failing per unit time. The failure rate of most electronic components follows the

characteristic pattern:

• Early failures are removed during the manufacturing process.

• The operational life is characterized by a constant failure rate.

• The wear out period is characterized by a rapidly increasing failure rate.

The failures in time (FIT) are given with a 60% conﬁdence level for the various type codes. By convention, FIT is expressed as 1 x 10^-9

failures per hour. Failure rate is also expressed as a percentage of failures per 1,000 hours.

e.g., 100 FIT = 1 x 10^-7failures per hour = 0.01%/1,000 hours

End of Life Deﬁnition

Catastrophic Failure: short circuit, open circuit or safety vent operation

Parametric Failure:

• Change in capacitance > ±10%

• Leakage current > speciﬁed limit

• ESR > 2 x initial ESR value

Environmental Compliance

As an environmentally conscious company, KEMET is working continuously with improvements concerning the environmental effects

of both our capacitors and their production. In Europe (RoHS Directive) and in some other geographical areas like China, legislation

has been put in place to prevent the use of some hazardous materials, such as lead (Pb), in electronic equipment. All products in this

catalog are produced to help our customers’ obligations to guarantee their products and fulﬁll these legislative requirements. The only

material of concern in our products has been lead (Pb), which has been removed from all designs to fulﬁll the requirement of containing

less than 0.1% of lead in any homogeneous material. KEMET will closely follow any changes in legislation world wide and makes any

necessary changes in its products, whenever needed.

Some customer segments such as medical, military and automotive electronics may still require the use of lead in electrode coatings.

To clarify the situation and distinguish products from each other, a special symbol is used on the packaging labels for RoHS compatible

capacitors.

Because of customer requirements, there may appear additional markings such as LF = Lead Free or LFW = Lead Free Wires on the

label.

Snap-In Aluminum Electrolytic Capacitors – PEH526, +125ºC

Construction

The manufacturing process begins with the anode foil being

electrochemically etched to increase the surface area and then

“formed” to produce the aluminum oxide layer. Both the anode and

cathode foils are then interleaved with absorbent paper and wound

into a cylinder. During the winding process, aluminum tabs are

attached to each foil to provide the electrical contact.

Extended cathode

Anode foil

Foil tabs

The deck, complete with terminals, is attached to the tabs and then

folded down to rest on top of the winding. The complete winding

is impregnated with electrolyte before being housed in a suitable

container, usually an aluminum can, and sealed. Throughout the

process, all materials inside the housing must be maintained at the

highest purity and be compatible with the electrolyte.

Tissues

Cathode foil

Each capacitor is aged and tested before being sleeved and

packed. The purpose of aging is to repair any damage in the oxide

layer and thus reduce the leakage current to a very low level. Aging

is normally carried out at the rated temperature of the capacitor and

is accomplished by applying voltage to the device while carefully

controlling the supply current. The process may take several hours

to complete.

Decking

Assembly

Aging

Damage to the oxide layer can occur due to variety of reasons:

• Slitting of the anode foil after forming

• Attaching the tabs to the anode foil

• Minor mechanical damage caused during winding

A sample from each batch is taken by the quality department after

completion of the production process.

The following tests are applied and may be varied at the request

of the customer. In this case the batch, or special procedure, will

determine the course of action.
