TDK has launched a new film capacitor series for DC link applications with a smaller size than previously and high capacitance density and high current capability.
The EPCOS B3277X/Y/Z film capacitor series is designed for voltages between 500 and 1200 V DC with standard capacitance from 1.5 to 170 μF. The current capability is up to 36.5 A.
Depending on the voltage and capacitance, the lead spacings are 27.5, 37.5 and 52.5 mm, with both 4-pin or 2-pin versions available for each lead spacing. The maximum operating temperature of the RoHS-compatible components is 105 °C. At a rated voltage and an operating temperature of 85 °C the typical service life of the self-healing film capacitor series is 60,000 hours.
The Metallized Polypropylene (MKP) film capacitors are suitable for use in DC link circuits, as DC filters and for power factor correction for industrial converters, as well as for power supplies with higher reliability requirements. These applications include X-ray equipment, LED street lighting, induction hobs and electrical chargers.
