Shelf Life

The capacitance, ESR and impedance of a capacitor will not change signicantly 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 specication under each product series for specic 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 specied limit. During re-aging, a maximum charging current of twice the specied leakage

current or 5 mA (whichever is greater) is suggested.

Reliability

The reliability of a component can be dened 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. Therefore, we

must utilize probability theory. It is also necessary to clearly dene the level of stress involved (e.g., operating voltage, ripple current, temperature and time). Finally, the meaning of satisfactory performance must be dened by specifying a set of

conditions that determine the end of life of the component.

λt

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

perform satisfactorily for time t, and λ is the failure rate.

, where R(t) is the probability that the component will

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% condence level for the various type codes. By convention, FIT is expressed

−9

as 1 x 10 failures per hour = 0.01%/1,000 hours.

End of Life Denition

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

failures per hour. Failure rate is also expressed as a percentage of failures per 1,000 hours, e.g., 100 FIT = 1 x 10-7

Time

MTBF

The mean time between failures (MTBF) is simply the inverse of the failure rate.

MTBF= 1/λ

The failure rate is derived from our periodic test results. The failure rate (λR) is, therefore, only given at test temperature for

life tests. An estimation is also given at 40°C. The expected failure rate for this capacitor range is based on our periodic test results for capacitors with structural similarity. Failure rate is frequently quoted in FIT (Failures In Time) where 1 FIT = 1 x 10-9 failures per hour. Failure rate per hour includes both catastrophic and parametric failures.

Environmental Compliance

All Part Numbers in this datasheet are Reach and RoHS compliant and Halogen-Free.

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 such as 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 fulll these legislative requirements. The only material of concern in our products has been lead (Pb), which has been removed from all designs to fulll the requirement of containing

less than 0.1% of lead in any homogeneous material. KEMET will closely follow any changes in legislation worldwide and make 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.

Due to customer requirements, there may appear additional markings such as lead-free (LF), or lead-free wires (LFW) on the label.

Mechanical Data

Polarity and Reversed Voltage

Aluminium Electrolytic capacitors manufactured for the use in DC applications contain an anode foil and a cathode foil. As such, they are polarized devices and must be connected with the +ve to the anode foil and the -ve to the cathode foil. If this were to be reversed, then the electrolytic process that took place in forming the oxide layer on the anode would be recreated in trying to form an oxide layer on the cathode. In forming the cathode foil in this way, heat would be generated and gas would be given off within the capacitor, usually leading to a catastrophic failure.

The cathode foil already possesses a thin stabilized oxide layer. This thin oxide layer is equivalent to a forming voltage of approximately 2 V. As a result, the capacitor can withstand a voltage reversal of up to 2 V for short periods. Above this voltage, the formation process will commence. Aluminium Electrolytic capacitors can also be manufactured for the use in intermittent AC applications by using two anode foils in place of one anode and one cathode.

Mounting Position

The capacitor can be mounted in any position as long as the safety vent can operate. It is possible for some electrolyte to be expelled. As this is a conducting liquid, suitable precautions should be initiated by the system designer to avoid secondary short circuits.

The capacitors are designed to be mounted in free air and are not suitable for submersion in liquid.

Insulating Resistance

≥ 100 MΩ at 100 VDC across insulating sleeve.

Voltage Proof

≥ 3,500 VDC across insulating Sleeve ≥ 2,500 VAC across insulating Sleeve

Safety Vent

A safety vent for overpressure is featured on the terminal deck in the form of a rubber plug, designed to relieve build-up of internal pressure due to overstress or catastrophic failure.

Construction Data

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.

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.

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.

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. This sample size is controlled

by the use of recognized sampling tables de ned in BS 6001.

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.
