Type BLC series uses the most advanced metallized lm technology for long life and high reliability in DC Link applications. This series combines high capacitance and very high ripple current capability needed for today’s in verter designs for medium power wind, solar, fuel cells, UPS systems and more.

Available in values 8 to 55 µF and voltage ratings ranging from 700 to 1100 Vdc, type BLC DC link capacitors are packaged in UL94V-0 plastic boxes with 4 pins for low equivalent series resistance. These capacitors are designed for long life at high ripple current, up to 36A, with a demonstrable 25 year life under typical operating conditions.
