B25645A High Power ModCap™ Capacitors

TDK B25645A High Power ModCap™ Capacitors feature a modular capacitor concept for DC link applications. This series offers rated voltages of 1100V to 2300V and covers a 365µF to 3900µF capacitance range. The rated currents between 105A and 180A are type-conditioned with all types designed for 5kA recurrent pulse currents. The maximum permitted hot spot temperature is 90°C. In contrast to conventional cylindrical designs, the B25645A series is cubic in design and available in 243mm x 169.5mm x 90mm or 258mm x 215mm x 115mm dimensions, which can be fitted close to IGBT modules for short lead lengths. This, combined with a low 14nH self-inductance, stops any substantial voltage overshooting at the IGBT modules when the current is shut off. As a result, no snubber capacitors are generally needed. This design also simplifies parallel connections of capacitors. The artificial resin-filled plastic housings comply with UL 94V-0 standards. The capacitors meet the fire and smoke formation requirements, in line with IEC 61071, IEC 61881-1, EN 45545-2 HL3 R23. TDK B25645A High Power ModCap Capacitors are well suited for use in trains as well as traction, renewable energies, and industrial applications.
