The ALH126K351C064 is an AEC-Q200 qualified AC filter capacitor for harsh environments, rated at 350 Vac and 12 µF with ±10% tolerance. It has an ESR of 6.8 mΩ at 10 kHz and supports a peak dv/dt of 28 V/µs and a maximum rms current of 14 A at 10 kHz and 70°C hot spot. Operating temperature ranges from -40 °C to 105 °C, with voltage derating above 85 °C. Its dimensions are 57.5 mm in length, 45 mm in height, and 30 mm in width, with a terminal pitch of 20.3 mm and lead diameter of 1.2 mm. The device is RoHS compliant, features self-healing and low loss, and has a rated life of 100,000 hours at 70 °C. Case and resin are UL94V-0, with tin-plated copper terminals and UL recognition E128034.
AC Filter Capacitors for Harsh Environments 12µF 350V
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.
