Hermetically Sealed 125°C AC Capacitor
The MH series hermetically sealed capacitors are specifically designed for 400Hz AC filtering in high reliability applications. ECI’s 125⁰C metallized dielectric system, combined with unique proprietary process development, yields superior performance and electrical characteristics to traditional 125⁰C dielectric choices like polycarbonate or PPS. MH style capacitors have been employed in critical aerospace and marine 400Hz AC applications since 2002. ECI’s critical process development and testing insures our customers receive only the highest reliability capacitors.
