Film capacitors series is one of jb Capacitors Company’s strong series. There are several series of film capacitors, some of them are mini nature size including JFF,JFH,JFJ,JFE. These series are able to use on the printed circuit board(PCB) when you have size limitation. These series are Metallized Polyester Film Capacitor. JFH and JFE are Dipped type capacitors, on the other hand JFF and JFJ are Box type capacitors.
Recently, Panasonic has discontinued their ECQ-V series, these can be one of your another choice. If there is any trouble to find the suitable one to replace, JFF,JFH,JFJ,JFE will be a good back up plan. Please contact with our sales as soon as possible.
