Product Overview

The SAMXON KM Series Aluminum Electrolytic Capacitors are polar, foil-type capacitors designed for use in electronic equipment. Meeting IEC60384 standards, these capacitors feature a single-ended construction with terminals fixed to anode and cathode foil, wound with paper, and impregnated with electrolyte. They are enclosed in an aluminum case, sealed with end seal rubber, and finished with a vinyl sleeve. This specification applies to the KM Series, version 01.
