New MKP1847C AC Filtering Film Capacitors Withstand THB Testing of 40 °C, 93 % RH for 56 Days at Rated Voltage, Deliver Extremely Stable Capacitance and ESR in High Humidity Environments
Vishay Intertechnology introduces a new series of metallized polypropylene AC filtering film capacitors optimized for high humidity environments. Vishay Roederstein MKP1847C AC Filtering devices withstand demanding temperature humidity bias (THB) testing — 40 °C, 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
