Overview
The Sangamo CP41B1EF205K capacitor is a fixed paper-dielectric component with hermetically sealed construction, manufactured to industrial military standards. Rated at 2µF and 600 WVDC, this vintage Sangamo CP41B1EF205K unit is designed for high-reliability applications where oil-filled paper construction provides superior performance characteristics. Originally produced by Sangamo Electric Company (now part of Cornell Dubilier Electronics), these capacitors remain valued for restoration work and legacy equipment maintenance.
