BLH105K451A012 is a DC link capacitor designed for harsh environments, rated for 450 Vdc with a capacitance of 1 µF and ±10% tolerance. It features a plastic UL94V-0 case, tin-plated copper terminals, and is qualified to AEC-Q200 standards. The part measures 32 mm in length, 18 mm in height, and 9 mm in thickness, with a 27.5 mm lead pitch and 0.8 mm lead diameter. It supports a maximum rms current of 2.5 A at 10 kHz, has an ESR of 45 mΩ, and operates from -40 °C to 105 °C with derating above 85 °C. The capacitor meets IEC 61071 and is UL recognized (E128034) for construction only. Its THB rating is 85 °C / 85% RH for 1500 hours at rated voltage, and it has a life expectancy of 100,000 hours at 70 °C hot spot temperature.
