Robust DC link capacitors

TDK Corporation has extended its portfolio of EPCOS film capacitors for DC link applications with the robust new B3277*M series. The new types are suitable for extreme environmental conditions at 185 °F (85 °C), 85% relative humidity with a rated voltage applied for 1000 hours. The capacitors of the new series are designed for rated voltages of between 450VDC and 1600VDC and offer capacitance values of between 0.33  µF and 120  µF. The maximum operating temperature of these RoHS-compatible components is 221 °F (105 °C). Depending on the voltage and capacitance, the lead spacings are 27.5mm, 37.5mm and 52.5mm, and a 2-pin or 4-pin version is available for each lead spacing. The service life of the self-healing capacitors is 50,000 hours at the rated voltage and an operating temperature of 185 °F (85 °C). Typical applications include DC links of converters for photovoltaic plants, as well as frequency converters and power supplies for industrial applications. The series is qualified in accordance with AEC-Q200.
