jb Capacitors Company Mini Size MKT capacitors-JFF,JFH,JFJ,JFE

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.

jb Occupy Market Share of Fine-Tuning Capacitors(Ceramic Trimmer capacitor)

Ceramic Trimmer capacitor is a semi-fixed adjustable capacitor, and its electrostatic capacity can be changed freely.

The working principle of JKA trimmer capacitor: Change the overlapping area of electrodes. One of the electrodes is fixed to sandwich the dielectric, and the other is made as a variable electrode. The change in the overlapping area of the two electrodes (the area of the opposite electrode) can change the electrostatic capacitance.

jb Capacitors Company’JKA series: surface mount ceramic trimmer capacitors with mini size, five kinds of capacitance values, different color is easily identified.
