High Current

The Electrocube 985B series is a rugged, non-inductively wound double metallized high current capacitor. Proudly made in the U.S. with proprietary techniques, it offers high frequency operation, high current and low ESR in a miniature package. The 985B series is part of Electrocube’s designated line of capacitors specially designed and optimized for high temperature, high current applications subject to AC and pulsing signals. Able to handle high surge currents without degrading, this series is an excellent replacement for electrolytic capacitors. Engineers prefer the 985B series high-grade materials, design and manufacturing for high-powered inverter applications; rugged military and commercial land and sea applications; AC power, solar-, wind-, and steam-power generation, and avionics, electric vehicles and robotics.
