The BLH406K122C144 is a DC link capacitor designed for harsh environments, rated for 1200 Vdc and 40 µF capacitance with ±10% tolerance. It features a plastic UL94V-0 case, tin-plated copper terminals, and is qualified to AEC-Q200 standards. The part has a maximum operating temperature of 105 °C, with voltage derating above 85 °C at 1.35% per °C. It supports a peak current of 1200 A at 10 kHz and has an expected life of 100,000 hours at a 70 °C hot spot. Dimensions are 57.5 mm length, 65 mm height, 45 mm width, with a terminal pitch of 20.3 mm and lead diameter of 1.2 mm. The capacitor meets IEC 61071 and is designed for high ripple current and self-healing performance.
