After years of study, jb finally successfully developed a new series of capacitors for capacitive divider.

This kind of capacitor is specifically designed for applications in serial with the 100~240Vac MAIN.
Such as a small power LED driver module, small household electrical appliances control panel (electric kettle, electric cooker, coffee machine, hair straightener etc.), 
thermostat, replace the transformer. Also widely used in LC resonant, high frequency high current situation.

Below is the Typical Circuit for jb Box Type MKP Film Capacitors For Capacitive Divider JFMA：

In this special celebrating season, jb Capacitor want to share with you our super popular Motor Starting Capacitors Series, which comes with UL and cUL approvals and three different types. You name it, we have it! Quickly send us your RFQs by email. Special promotion within offer in this celebrating season.
