Tantalum Surface Mount Capacitors – MIL–PRF (CWR Style)

T492 Series MIL–PRF–55365/8 (CWR11 Style)

Overview

The KEMET T492 Series is approved to MIL–PRF–55365/8

(CWR11 Style) 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 inspec-

tion, 100% visual inspection, DCL and ESR measurements 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 version of the

global IEC/EIA standard represented by KEMET's T491 Series.

Tape and reeling per EIA 481 is standard.
