B3277*X/Y/Z Series Film Capacitors

TDK Corporation extends the portfolio of EPCOS film capacitors for DC link applications with the B3277*X/Y/Z series. The capacitors feature compact dimensions, high capacitance density, and high current capability. They are designed for rated voltages between 500 V_DC and 1200 V_DC. The series offers numerous standard capacitance values within the range of 1.5 µF to 170 µF.

Depending on the voltage and capacitance, their lead spacings are 27.5 mm, 37.5 mm, and 52.5 mm, with both 4-pin or 2-pin versions available for each lead spacing. The maximum operating temperature of these 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 capacitors is 60,000 hours.

These metallized polypropylene film capacitors (MKP) 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.
