Product Description

Product Overview

The C21 CL21/CL21X Series Capacitor is a metallized polyester film capacitor designed for DC and VHF signal applications. It is suitable for DC blocking, by-pass, and coupling, and is widely used in filter and low pulse circuits. Key features include a non-inductive wound construction, wide capacitance range, small size, light weight, self-healing properties, and long life. The capacitor is encapsulated in flame-retardant epoxy resin powder coating (UL94/V-0).
