Rugged dc link film capacitors endure harsh conditions

TDK CORP B3277*H series range of EPCOS film capacitors for dc link applications provides types for particularly harsh environmental conditions. The robustness has been verified in a temperature, humidity, bias (THB) test at 60°C, 95% relative humidity and the rated voltage for 1000-hours. Special types are also available that are THB tested at 85°C, 85% relative humidity and the rated voltage for 1000 hours. Devices are designed for rated voltages of between 450Vdc and 1100Vdc and offer capacitance values of between 1.5µF and 120µF.
