Product Overview
The C21 CL21/CL21X Series Capacitor is a metallized polyester film capacitor designed for DC and VHF signal applications, including blocking, by-pass, and coupling. It is widely used in filter and low pulse circuits. This capacitor features a non-inductive wound construction, a wide capacitance range, small size, light weight, and a long life due to its self-healing effect. The flame-retardant epoxy resin powder coating ensures safety and durability.
