MIL–PRF (CWR Style) Established Reliability

T492 Series CWR11 Style MIL–PRF–55365/8

Overview

The

KEMET T492 Series is approved to MIL-PRF-55365/8

(CWR11) with Weibull failure rates of B level (0.1% failures per

1,000 hours), C level (0.01% failures per 1,000 hours), D level

(0.001% failures per 1,000 hours), or T level (0.01% failures

per 1,000 hours, Option C surge current, DPA, Radiographic

inspection, 100% visual inspection, DCL and ESR measure-

ments within +3 standard deviations, and Group C inspection).

This CWR11 product is a precision-molded device with compliant

terminations and indelible laser marking. This is the military ver-

sion of the global IEC/EIA standard represented by KEMET's T491

Series. Tape and reeling per EIA 481-1 is standard.
