Slim polypropylene film capacitor for solar inverters

Vishay Intertechnology has announced a new high-performance metallized DC polypropylene film capacitors in the capacitance range of 2 micro Farads up to 100 micro Farads, and voltage ratings of 500 VDC, 700 VDC, and 1,000 VDC for DC-link applications. The slim MKP1848S features low profiles of 12 mm, 15 mm, 18 mm, and 24 mm.

With a long life of > 100,000 hours at nominal DC voltage and + 70 °C, the MKP1848S is optimized for inverters, power supplies, solar micro-inverters, on-board chargers (EV/HEV), pumps, and LED drives.

The DC-link capacitor features capacitance tolerance down to ± 5 %, low self- inductance of < 1 nH per mm of lead spacing, high peak current capabilities to 900 A, and high RMS current to 22 A. Offered in a flame-retardant plastic case with a resin seal, the device features a high operating temperature to + 105 Deg C, is lead (Pb)-free and RoHS-compliant, and introduces halogen-free materials to Vishay's portfolio of film capacitors.

Samples are available now.
