For AC Filtering Applications, Device Offers Voltage Ratings from 230 V to 350 V (440 V Under Development)
Vishay Intertechnology announced a new metallized AC polypropylene film capacitor featuring a wide capacitance range from 1 µF up to 70 µF, long life of > 60,000 hours, and voltage ratings up to 350 V. A 440 V version is under development.
With its long life and available 230 V, 250 V, 275 V, 310 V, and 350 V voltage ratings, the MKP1847 is optimized for AC filtering in UPS systems, power supplies, inverter grid interface, and welding equipment. The device will typically be used in output filters and tuned LC and LCL circuits to mitigate undesirable frequencies and harmonics.
The AC capacitor features capacitance tolerance down to ± 5 %, low self inductance of < 1 nH per mm of lead spacing, high peak current capabilities up to 750 A, and high RMS current up to 32 A. Additionally, the MKP1847 uses segmented film technology for increased safety, in compliance with the UL810 standard. Offered in a flame-retardant plastic case with a resin seal, the robust device features a high operating temperature to + 105 °C and is compliant to RoHS Directive 2002/95/EC.
