Power capacitors: TDK introduces new DC link capacitors with exceptionally low ESL


TDK Corporation presents a new series of EPCOS power capacitors for DC link applications. The new capacitors are available for rated voltages of 700 V DC to 2000 V DC and cover a capacitance range of 20 µF to 270 µF. The current handling capacity can be up to 60 A at 65 °C with the ability to tolerate current peaks of up to 7.5 kA. The maximum permissible hot spot temperature is 85 °C.

The capacitors’ extremely low ESL values can be as low as 13 nH, 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. The low ESR value remains stable even at high switching frequencies of 100 kHz, 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.

Main fields of application

  • Fast-switching converters and inverters for photovoltaic systems, traction and inductive heating systems 

Main features and benefits

  • Rated voltage of 700 V DC to 2000 V DC
  • Capacitance range from 20 µF to 270 µF
  • Extremely low ESL of max. 13 nH, ESR of min. 0.9 mΩ
