Type ALH AC Filter Capacitors for Harsh Environments

Cornell Dubilier's ALH series of AC-rated filter capacitors offer 50% greater life on accelerated tests than other 85/85 THB-rated film capacitors. The temperature, humidity at bias (THB) test exposes parts to the harsh conditions of +85°C at 85% relative humidity with rated voltage applied.

The ALH series is optimized for AC harmonic filtering on the input and output of inverter circuits. Capacitance ranges from 0.22 µF to 50 µF at 160 V_AC to 450 V_AC, 50 Hz/60 Hz with high RMS current ratings for handling higher-ordered harmonics. These capacitors offer self-healing, metalized polypropylene-film in a robust board-mount package that meets the rigors of automotive AEC-Q200 testing. The solvent-resistant, box-style plastic case and resin-seal are UL/cUL 94 V-0 rated, and the series is UL/cUL recognized for construction. Terminations are RoHS-compliant with tin-plated copper terminations. Their superior construction makes these capacitors ideal for solar, wind, UPS, EV, and other inverter applications that may be subjected to a wide range of environmental conditions.
