TDK introduces a series of robust EPCOS MKP film capacitors (B3275*) that are optimized for use with AC voltages with high ripple currents. The new types are available for rated voltages of 250 VRMS, 275 VRMS and 310 VRMS and cover a capacitance range from 1 µF to 70 µF. One particular feature is their robustness: The capacitors pass a THB test (temperature, humidity, bias) at 60 °C, 95 percent relative humidity and a rated voltage applied for 1000 hours.
