Product Description
C21/CL21X Series Metallized Polyester Film Capacitors
The C21/CL21X series capacitors are metallized polyester film capacitors designed for DC and VHF signal applications. They are suitable for blocking, by-pass, and coupling functions, and are widely used in filter and low pulse circuits. These capacitors feature a non-inductive wound construction with a wide capacitance range, small size, light weight, and a long lifespan due to their self-healing effect. The exterior is encapsulated with flame-retardant epoxy resin powder coating (UL94/V-0).
