TDK Extends Range of Rugged EPCOS DC Link Film Capacitors
Iselin, N.J. (May 15, 2018) – TDK Corporation today announced that it has extended its range of EPCOS film capacitors for DC link applications. The B3277*H series now provides types for particularly harsh environmental conditions. The robustness has been verified in a temperature, humidity, bias (THB) test at 60 °C, 95 percent relative humidity, and the rated voltage for 1000 hours. Special types are also available that are THB tested at 85 °C, 85 percent relative humidity, and the rated voltage for 1000 hours.
The capacitors are designed for rated voltages of between 450 V DC and 1100 V DC and offer capacitance values of between 1.5 µF and 120 µF. The maximum operating temperature of the RoHS-compatible components is 105 °C. Depending on voltage and capacitance, the lead spacing is 27.5 mm, 37.5 mm, or 52.5 mm. The types with the latter grid size are offered exclusively in a 4-pin version. At the rated voltage and an operating temperature of 85 °C the service life of the self-healing capacitors is 50,000 hours.
Applications include the DC link circuits of converters for photovoltaic systems, frequency converters and power supplies for industrial applications. AEC-Q200 qualified capacitors are also available on request.
