The BLH305K451A022 is a DC link capacitor rated for 450 Vdc and 3 µF with ±10% tolerance, designed for harsh environments and AEC-Q200 qualified. It operates from -40 °C to 105 °C, with a THB rating of 1500 hours at 85 °C and 85% relative humidity under rated voltage. The plastic UL94V-0 case measures 32 mm in length, 20 mm in height, and 11 mm in thickness, with a 27.5 mm terminal pitch and 0.8 mm lead diameter. It has a 10 kHz ESR of 20 mΩ, thermal resistance of 49.3 °C/W, and a typical RMS ripple current of 4 A at 70 °C. Insulation resistance is ≥30,000 MΩ×µF at 100 Vdc after 1 minute. Life expectancy is 100,000 hours at 70 °C hot spot under rated voltage. UL recognized for construction only under E128034.
