ALH306K271C084 is an AC filter capacitor for harsh environments, rated for 275 V AC and 30 µF, with a capacitance tolerance of ±10%. It has an ESR of 5.3 mΩ at 10 kHz, a peak dv/dt rating of 25 V/µs, and a maximum RMS current of 14 A at 10 kHz and 70°C hot spot temperature. The capacitor operates from -40°C to 105°C with voltage derating above 85°C. It employs a self-healing film construction, has an insulation resistance of at least 30,000 MΩ·µF at 100 V DC, and is rated for 100,000 hours of life at 70°C hot spot under rated voltage. The case is made of UL94V-0 plastic, with tin-plated copper terminals, and measures 57.5 mm in length, 50 mm in height, 35 mm in width, with a lead spacing of 20.3 mm. It complies with IEC 61071, is AEC-Q200 qualified, RoHS compliant, and UL recognized as E128034.
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.
