B25695E* DC Link Power Capacitors

TDK/EPCOS' power capacitors for DC link applications are designed for operating temperatures up to +105°C. These components can operate at rated DC voltages from 700 V to 1,300 V (voltage derating necessary from +85°C). The ESR ranges from 1.0 mΩ to 2.7 mΩ, resulting in a current capability of up to 110 A at +70°C depending on the model (current derating necessary at higher temperatures). These film capacitors can repetitively withstand current peaks of up to 15.8 kA. At the rated voltage and at +75°C, their service life is 120,000 h (up to 35% more than the standard version).

The aluminum cylindrical cases of the RoHS-compatible capacitors have diameters of 85 mm or 116 mm and a synthetic resin lid. The metalized polypropylene film is encapsulated with a dry epoxy resin. M6 screw terminals ensure a secure electrical connection and an M12 threaded bolt on the bottom side provides a secure mechanical connection.
