TDK Corporation has introduced a new series of EPCOS power capacitors for DC link applications.
The new capacitors are available for rated voltages of 700V DC to 2,000V DC and cover a capacitance range of 20 µF to 270 µF. The current handling capacity can be up to 60A at 65°C with the ability to tolerate current peaks of up to 7.5kA. The maximum permissible hot spot temperature is 85 °C.
The capacitors’ extremely low ESL values can be as low as 13nH, depending on the type. Thanks to this and the low ESR values of min. 0.9 mΩ, the capacitors of the B2563xE* series are suitable for inverter solutions with fast-switching power modules. (ESL = Equivalent Series Inductance; ESR = Equivalent Series Resistance.)
The low ESR value remains stable even at high switching frequencies of 100kHz, while the low parasitic coefficients prevent significant voltage overshoots even when high currents are switched off.

The capacitors’ plastic cylindrical cases conform with UL 94 V0. Two connection types are available: M8 threaded bolts or M5 threaded holes. Typical applications include fast-switching converters and inverters for photovoltaic systems, traction in railway technology, and inductive heating systems.
The main fields of application include fast-switching converters and inverters for photovoltaic systems, traction, and inductive heating systems.
