Field proven reliability in 400Hz, 125°C AC filtering applications since 2002
The MH2 series of pressed wrap and fill capacitors are specifically designed for 400Hz AC filtering. The MH2 is a non-hermetic option offering better weight, cost, packaging efficiency and design flexibility when board potting or sealed systems do not require traditional hermetic sealed capacitors. The MH2 series combines ECI’s specialized 125⁰C metallized dielectric system with unique proprietary processing, testing, and screening. The MH2 series provides superior performance and electrical characteristics to traditional 125⁰C dielectric choices like polycarbonate or PPS. ECI’s critical process development and testing insures our customers receive only the highest reliability capacitors field-proven in military aerospace and naval applications since 2002.
Common applications include generator and inverter output filters in military aerospace and naval power systems, and ground based vehicle inverters. The technology is easily designed into custom capacitor requirements from a fraction of a microfarad to several hundred microfarads and 400Hz voltages to 250vac or higher at 125⁰C.
