Tantalum Surface Mount Capacitors – MIL–PRF (CWR Style)
T429 Series MIL–PRF–55365/11 (CWR29 Style)
Overview
The KEMET T429 Series is approved to MIL–PRF–55365/11
(CWR29 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 CWR29 product is a precision-molded device
with compliant terminations and indelible laser marking. Tape and
reeling per EIA 481 is standard.
