We have a series JFZA X2 for power meter / energy meter application!
After many years of experience in the meter, it proves that our JFZA series is a very good, very safe choice!

JFZA X2, 310VAC, 2,200pF~2.2uF, used in series connection.
The most popular values we sell are 0.1UF / 0.22UF / 0.47UF and 1UF. What about you? what values do you need in your production?
Welcome send to me your RFQ, let me quote and prepare samples for you to approve.

Below is our recommended circuit diagram, for your reference only.


 

After years of study, jb finally successfully developed a new series of capacitors for capacitive divider. 
X2 capacitors are used not only for EMI suppression, after upgraded, they are also suitable for voltage dividers in capacitive power supplies – for example, those of smart energy meters.

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 Class X2 MKP Film Capacitors For Capacitive Divider JFZA：

As capacitor voltage divider in applications requiring a high capacitance stability over time, we highly suggest you to use jb new designed capacitors, specifically designed for applications in serial with the 100~240Vac main. 

Features: 
For use in series with the 100~240Vac main
According to RoHS 2011/65/EU
High Capacitance stability for harsh environment.
Relevant for capacitive divider power supply, power meter, emergency lighting, thermostat, interference suppression.

Typical Capacitance and Values For Capacitive Divider:
394, 0.39uF 310VAC +/-10%, Pitch:22.5mm, LxTxH: (26.5x8.5x17mm) +/-1mm, Bulk Packing, RoHS
474, 0.47uF 310VAC +/-10%, Pitch:15.0mm, LxTxH: (18x8.5x14.5) +/-1mm, Bulk Packing, RoHS
105, 1.0uF  310VAC +/-10%, Pitch:22.5mm, LxTxH: (26.5x10x19) +/-1mm, Bulk Packing, RoHS

jb Capacitors R&D department accumulate years of experience in film capacitors, in year 2018 we develop a kind of capacitors especially use in serial circuit.
This kind of capacitors is for Capacitive Divider application.Below are our 3 different series of them. The X2 type with best performance 

JFLA - Dipped Metallized Polypropylene Film Capacitor For Capacitive Divider 
JFMA - Box Type Metallized Polypropylene Film Capacitor For Capacitive Divider 
JFZA - 310VAC X2 Metallized Polypropylene Film Capacitor For Capacitive Divider
