New AC Filtering Film Capacitors Deliver Extremely Stable Capacitance

Vishay New AC Filtering Film Capacitors Deliver Extremely Stable Capacitance and ESR in High Humidity Environments

Vishay Intertechnology introduces a new series of metalized polypropylene AC filtering film capacitors optimized for high humidity environments.

Vishay Roederstein MKP1847C AC Filtering devices withstand demanding temperature humidity bias (THB) testing —40C, 93 % relative humidity for 56 days at rated voltage —without altering their electrical characteristics.

• Designed to ensure extremely stable capacitance and ESR values over a long service life under harsh environmental conditions during operation
• Compared to previous-generation devices, the MKP1847C AC Filtering series offers higher humidity robustness at a lower cost while maintaining the same footprint.

Product Benefits:

• Withstand THB testing —40C, 93 % relative humidity for 56 days at rated voltage
• Wide capacitance range from 1 μF up to 70 μF, with tolerance down to +/-10 %
• Rated voltages of 230 VAC, 250 VAC, 275 VAC, 310 VAC, and 350 VAC
• Low self-inductance of < 1 nH per mm of lead spacing
• High peak current capabilities up to 750 A
• High RMS current up to 26 A
• Offered in a flame-retardant plastic case with a resin seal
• High operating temperature to +105C

Market Applications:

• Input and output filtering in UPS systems, renewable energy inverter grid interfaces, and welding equipment
