Film capacitors: MKP types for up to 125 °C

TDK Corporation presents a new series of EPCOS MKP (metallized polypropylene) film capacitors for DC link and DC filter applications. The outstanding feature of these components is their high permissible operating temperature of 125 °C. The capacitors are offered with rated voltages of 630 V DC, 700 V DC and 840 V DC in a broad range of capacitances from 1 µF to 50 µF.

The lead spacing of the new DC link capacitors with the ordering codes of B32774P* to B32778P* may be 27.5 mm, 37.5 mm or 52.5 mm. In order to achieve high mechanical stability on the PCB, 4-pin versions are offered for the two larger lead spacings, and types with a lead spacing of 27.5 mm are available with a wire diameter 1 mm. Both the enclosure and the casting compound comply with flame retardant category UL 94 V-0. The RoHS-compatible capacitors offer high current capabilities of up to 23.5 A_RMS.

With their low ESL and ESR values, the new EPCOS capacitors are suitable for inverters and power supplies in industrial electronics or for DC-DC converters in automotive electronics.

Main applications

• Inverters
• Power supply units
• DC-DC converters and compressors for automotive electronics

Main features and benefits

• High permissible operating temperature of up to 125 °C
