Film capacitors for AC applications
11 October 2017, Passive Components

EPCOS MKP film capacitors of the B3275 series are optimised 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 extreme robustness: the capacitors pass a THB test (temperature, humidity, bias) at 60°C, 95% relative humidity and a rated voltage applied for 1000 hours.

The new MKP film capacitors are designed for a maximum operating temperature of 105°C, and both their case and the epoxy resin sealing comply with UL 94 V-0. Depending on capacitance and voltage class, the lead spacings are 27,5 mm, 37,5 mm or 52,5 mm, with 4-pin versions offered for the two larger lead spacings.

The capacitors feature a long expected lifetime of more than 60 000 hours at a temperature of 70°C and 90% of the rated voltage. Typical applications are the output filters of frequency converters, uninterruptible power supplies and variable-speed drives.
