Tantalum Surface Mount Capacitors – MIL-PRF (CWR Style)
T419 MIL-PRF-55365/11 (CWR19 Style)
Overview
The KEMET T419 is approved to MIL-PRF-55365/11
(CWR19 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 inspection, 100% visual
inspection, DCL and ESR measurements within +3 standard
deviations, and Group C inspection). This CWR19 product is
a precision-molded device with compliant terminations and
indelible laser marking. Tape & Reel packaging per EIA 481 is
standard.
