The ALH156K271B104 is an AC filter capacitor designed for harsh environments, rated for 275 Vac at a maximum operating temperature of 105°C with voltage derating above 85°C. It has a capacitance of 15 µF with a tolerance of ±10%, an ESR of 5.1 mΩ at 10 kHz, and a peak dv/dt rating of 30 V/µs. The capacitor supports a rated rms current of 14 A at 10 kHz and 70°C hot spot temperature. Its dimensions are 42.5 mm in length, 45 mm in height, and 30 mm in thickness, with a lead spacing of 20.3 mm. It features self-healing, low loss, and is qualified to AEC-Q200 with an 85°C/85% RH 1500-hour THB rating. The case is made of UL94V-0 plastic with tin-plated copper terminals, and it meets IEC 61071 and RoHS standards.
AC Filter Capacitors for Harsh Environments 15µF 275V
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.
