Components of butyl has recently introduced a gf G series for HCL need that will be used and made up of metallized polyester and polypropylene film capacitor that will be along with providing features such as large capacity and good self healing along with temperature resistance to the devices and hardware in which they are incorporated. They will be readily available for applications such as direct current and alternating current circuits for providing fractional frequency circuit of excuses systems .The JFGC and JFGD series cover input voltages of 250, 400, 630, 1000 and 1250Vdc. The JFGC series is available from 47000pF to 56µF with ±10% tolerance .
