T492 MIL-PRF-55365/8 (CWR11 Style)
Overview
The KEME T T492 is approved to MIL-PRF-55365/8 ESR measurements within +3 standard deviations, and Group
(CWR11) with Weibull failure rates of B level (0.1% failures C inspection). This CWR11 product is a precision-molded de-
per 1,000 hours), C level (0.01% failures per 1,000 hours), vice with compliant terminations and indelible laser marking.
D level (0.001% failures per 1,000 hours), or T level (0.01% This is the militar y version of the global IEC/EI A standard,
