  • 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

Availability:

Samples and production quantities of the MKP1847C AC Filtering series are available now, with lead times of 12 weeks.
