Meter measurement circuit (three-phase)

The TDK Group recently introduced a new EPCOS MKP (metallized polypropylene) film capacitor family (B3275*), which is ideally suited for high ripple current AC applications. The new series of capacitors are rated for 250 VRMS, 275 VRMS, and 310 VRMS, respectively, and capacitance values ​​from 1 μF to 70 μF. Its outstanding highlights are its superior resistance to moisture and heat, which can be tested by the high temperature and humidity (THB) test (rated voltage, ambient temperature of 60°C, and continuous pressurization at 95% relative humidity for 1,000 hours).

This new series of capacitor products has three types of terminals for customers to choose from: M6 to M10 screw terminals, blade type, or clip type terminals. The studs at the bottom of the capacitor are used for secure fixation and grounding. The capacitor has a self-healing function and is internally equipped with an over-pressure disconnected safety mechanism.
