Cornell Dubilier releases new series of long life, 85/85 THB-rated AC filter capacitors. Designed for harsh environments, the 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. 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 moisture penetration.
The ALH Series is optimized for AC harmonic filtering on the input and output of inverter circuits. With high rms current ratings for handling higher-ordered harmonics.
