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. Benefits • Designed for automotive applications • 3,000 hours at +125°C (VR, IR applied) • Resistance to vibrations • Low ESR • High ripple current capability Part Number System PEH526 H AB 427 0 M 3 Series Voltage (VDC) Size Code Capacitance Code (µF) Version Capacitance Tolerance Termination See Dimension Table The second two digits indicate the two most significant digits of the capacitance value.

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 10-7 failures 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 © KEMET Electronics Corporation • P.O.

MTBF= 1/λ Failure Rate early failures wear out operational life Time 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. © KEMET Electronics Corporation • P.O.

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 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. 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.
