Condenser Products Overview
Container TypesOur dielectric systems are identifiable by the first one or two letters of the part number prefix. Our impregnant types are identifiable by the letter following the dielectric system letters. Our container types are readily identifiable by the last letter of the part number prefix.
Capacitor CostCapacitor cost is determined by these factors: capacitor energy, operating voltage, container type & size, terminations, and the dielectric system (as per application). Containers, in order of lowest cost, are cylindrical glass, thermoplastic, paper phenolic, and rectangular metal cans. Dielectric systems, in order of lowest cost, are Kraft/polypropylene (KN), Kraft/Polyester (KM), all polypropylene (N), all Polyester (M), and all teflon (T).
The small volume available in cylindrical glass units limits the energy in DC applications to 10 joules—and accordingly less when derated for pulse and AC applications.
