EPCOS B2563xE* series DC link capacitors from TDK

The TDK B2563xE* series of power capacitors is designed for DC-link applications. The new capacitors are available for rated voltages of 700VDC to 2000VDC and cover a capacitance range of 20µF to 270µF. 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. 0.9mΩ, the capacitors of the B2563xE* series are suitable for inverter solutions with fast-switching power modules. 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 94V0. 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.
