Product Description

Combining the low ESR of multilayer ceramic, the high capacitance of aluminium electrolytic and the volumetric efficiency of tantalum into a single surface mount package, the KEMET Organic Capacitor (KO-CAP) offers low ESR and improved retention at high frequencies, with a very long operational life and high ripple current capabilities.

Developed for high stability and reliability under harsh environmental conditions, the T598 features special enhancements to deliver 1,000 hours under 85°C/85% RH/VR and to fully comply with AEC-Q200 Qualification Testing. The T598 is manufactured in a ISO TS 16949 certified plant and is subjected to PPAP/PSW and change control.

Typical applications include decoupling and filtering in a variety of market segments, with special emphasis in automotive applications such as infotainment and input/output in DC/DC converters where harsh conditions such as high humidity and temperature are a concern.

High reliability

Specially enhanced design offers up to 1,000 hours with 85°C/85% RH load.

RoHS Compliant

Compliant with EU restrictions on the use of hazardous substances in electrical and electronic equipment.

Ultra low ESR

Low ESR offers longer load life and increased stability at a range of temperatures.
