Long Life, 85/85 THB-Rated AC Filter Capacitors for Harsh Environments

1,500-hour rating is 50% greater than competitors’ series. 

Liberty, SC (3/22/2021) – Designed for harsh environments, Cornell Dubilier’s new ALH series of AC-rated filter capacitors offer 50% greater life than competitive 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. CDE’s testing has been validated for 1,500 hours, while competitors validate their series for 1,000 hours under the same conditions. This demanding test simulates the extremely harsh operating conditions encountered in many commercial and industrial inverter applications that can cause conventional film capacitors to fail early due to heat and moisture penetration.

The ALH Series is optimized for AC harmonic filtering on the input and output sides of inverter circuits. Capacitance ranges from 0.22 to 50 µF at 160-450 Vac, 50/60Hz with high rms current ratings for handling higher-ordered harmonics.

The series offers self-healing, metalized polypropylene-film construction in a robust board-mount package that also meets the rigors of automotive AEC Q200 testing. The solvent-resistant, box-style plastic case and resin-seal are both UL/cUL 94V-0 recognized for construction designs, with tin-plated copper RoHS compliant terminations. Their superior construction makes these capacitors ideally suited for solar, wind, UPS, EV, and other inverter applications that may be subjected to wide-ranging environmental conditions.

ALH Series film capacitors are available now from the company’s franchised distributors.
