Axial Aluminum Electrolytic Capacitors PEG124 Series, +105ºC and +125ºC Overview Applications KEMET's PEG124 is an electrolytic capacitor with very long-life and outstanding electrical performance. The device has a polarized allwelded design, tinned copper wire leads, a negative pole connected to the case, and plastic insulation. long-life and very high reliability are achieved by dimensioning of the capacitor, careful selection of materials/methods and discipline in quality control allowing operation up to +125°C/+105°C. KEMET's PEG124 is a high performance axial electrolytic capacitor. Typical applications include smoothing, coupling/ decoupling and energy storage in telecommunication, power supply system, data processing, process control and measuring where long life and high reliability are of paramount importance. The PEG124 winding is housed in a cylindrical aluminum can with a high purity aluminum lid and high quality rubber gasket. The sealing system is designed for electrolyte leakage-free operation and a very low gas-diffusion rate of electrolyte. Low ESR is the result of a low resistive electrolyte/paper system and an all-welded design. Benefits • Operating temperature of +125°C and +105°C • Very long life, up to 27,500 hours at +105°C • Low ESR • Low ESL • Polarized all-welded design • Outstanding electrical performance Click image above for interactive 3D content Open PDF in Adobe Reader for full functionality Part Number System PEG124 E F 410 0 Q T1 Series Voltage (VDC) Size Code Capacitance Code (µF) Version Capacitance Tolerance Packaging 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 ten years at 40°C. See sectional specification under each product series for specific data. Failure Rate Estimated field failure rate: ≤ 1.0 ppm (failures per year/produced number of capacitors per year). The expected failure rate for this capacitor range is based on field experience for capacitors with structural similarity. 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. Anode foil The winding is assembled to the capacitor Al-can and to the Al-lid. The can is filled with electrolyte and the winding is impregnated during a vacuum treatment. The capacitor is 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 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 carried out at elevated temperature and is accomplished by applying voltage to the device while carefully controlling the supply current. The process takes between 2 and 20 hours, depending on voltage rating. Damage to the oxide layer can occur due to a variety of reasons: • Slitting of the anode foil after forming • Attaching the tabs to the anode foil • Minor mechanical damage caused during winding The following tests are applied for each individual capacitor. Electrical: • Leakage current • Capacitance • ESR • Tan Delta Mechanical/Visual: • Pull strength test of wire terminals • Print detail • Box labels • Packaging, including packed quantity Foil tab Tissues Cathode foil Etching Forming Winding Assembly Filling (elyt) Impregnation Sealing Aging Testing Labeling Packing © KEMET Electronics Corporation • P.O.
