Compared to other THB-rated board-mount AC harmonic filter capacitors, the ALH series offers 50% greater life, providing 1,500-hour load life based on +85°C at 85% relative humidity with rated voltage applied. Competitive brands offer product with 1,000-hour max load life under the same conditions. The ALH is able to withstand harsh, humid conditions and offers high capacitance with high ripple current. Self-healing construction adds to the device reliability.
