TDK has expanded the high-density series of EPCOS MKP film capacitors with two new voltage classes. The B32774* to B32778* series of DC link film capacitors are now available for rated voltages of 575 V and 900 V d.c. This adds to the previously available rated voltages of 450 V, 800 V, 1100 V and 1300 V d.c.
The capacitors offer capacitance values ranging from 1,0 μF to 110 μF and are designed for operating temperatures of up to 105°C. Thanks to their low ESR values of down to less than 2,0 mΩ, they feature a current capability of up to 20 ARMS at 70°C and 10 kHz.
The components exhibit minimal capacitance drift over the entire operating life of 200 000 hours. They are self-healing, which significantly reduces the risk of failure even in the event of peaks and over-voltages.
Due to their very good electrical characteristics, the EPCOS MKP high-density series is suitable for use in DC link and DC filtering functions in power converters. Thanks to their long operating lives the capacitors can be used in applications with high demands on reliability. Examples are power supplies in industrial electronics such as photo-voltaic inverters, X-ray equipment, LED street lighting, induction cooktops and charging devices.
The capacitors are available with a lead spacing of 27,5 mm to 52,5 mm for PCB mounting. In addition to the conventional 2-pin designs, 4-pin designs offer enhanced mechanical stability against shocks and vibration so that the capacitors can be used in automotive electronics applications as well.
