INTRODUCTION CL21X are non-inductively wound with metallized polyester film as the dielectric/electrode with copper-clad steel leads and epoxy resin coating. FEATRUES Wide capacitance range,small size, high capacitance rate Long life due to self-healing effect Suitable for blocking,by-pass and coupling of DC and signals to VHF range Widely used in filter, used in filter,noise suppression and low pulse circuits
