ALH155K251A022 is an AC filter capacitor for harsh environments, rated for 250 Vac and 1.5 µF capacitance with ±10% tolerance, designed for high-frequency applications in automotive-grade applications. It features a plastic UL94V-0 case, tin-plated copper terminals, and measures 32.0 mm in length, 20.0 mm in height, and 11.0 mm in terminal spacing. The part supports operation from -40 °C to 105 °C, with a 300 Vdc DC rating, 8 A ripple current at 10 kHz and 70 °C, and a 100,000 hour life expectancy at 70 °C hot spot temperature. It meets AEC-Q200 qualification and IEC 61071 standards, is RoHS compliant, and includes self-healing and low-loss construction. The maximum rated voltage derates by 1.35% per °C above 85 °C.
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 moisture penetration.
The ALH Series is optimized for AC harmonic filtering on the input and output of inverter circuits. Capacitance ranges from 0.22 to 50 uF at 160-450 Vac, 50/60Hz with high rms current ratings for handling higher-ordered harmonics.
The series offers self-healing, metalized polypropylene-film 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 inverters applications that may be subjected to wide-ranging environmental conditions.
