Most capacitor ratings and styles are approved to MIL-C-55514/11, styles CFR26 & CFR27; and MIL-C-55514/12, style CFR29.
The type 5MC is a new miniature polycarbonate film capacitor that is designed specifically for switch-mode power converters. It is the first of a series developed by Electronic Concepts for switch-mode applications that offers a miniature configuration to conserve printed circuit board space, with low ESR, excellent ripple capacity, and high resonant frequency.
