BLH206K551B084 is a DC link capacitor rated for 550 Vdc with a capacitance of 20 µF, designed for harsh environments and AEC-Q200 qualified. It features a plastic UL94V-0 case, tin-plated copper terminals, and a thermal resistance of 9.8 °C/W at 70 °C. The component has a maximum rms current of 12.5 A at 10 kHz, a typical ESR of 6.5 mΩ, and dimensions of 42.5 mm in length, 40 mm in height, and 20 mm in thickness, with a 37.5 mm lead pitch and 10.2 mm lead diameter. It operates from -40 °C to 105 °C and complies with IEC 61071. The capacitor supports self-healing and low loss, with a 1500-hour reliability test at 85 °C and 85% relative humidity under rated voltage. Its insulation resistance exceeds 30,000 MΩ×µF at 100 Vdc and 25 °C.
