Robuste DC link kondensatorer
Med sigte på brug i applikationer med ekstreme miljømæssige påvirkninger lancerer TDK en nye serie af DC link kondensatorer (in english).
TDK Corporation has extended its portfolio of EPCOS film capacitors for DC link applications with the robust new B3277M series. The new types are suitable for extreme environmental conditions – a fact that has been proven by means of a THB test (temperature, humidity, bias) at 85 °C, 85 percent relative humidity with a rated voltage applied for 1000 hours.The capacitors of the new series are designed for rated voltages of between 450 V DC and 1600 V DC and offer capacitance values of between 0.33 µF and 120 µF. The maximum operating temperature of these RoHS-compatible components is 105 °C. Depending on the voltage and capacitance, the lead spacings are 27.5 mm, 37.5 mm and 52.5 mm, 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 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.
