Robust DC link capacitors

1 December 2019 Passive Components

TDK’s new B2568* series of EPCOS MKP DC link power capacitors offer high robustness under harsh environmental conditions. The new capacitors are designed for voltages of between 900 and 3000 V d.c. and cover a capacitance range from 50 to 4000 µF. Depending on type, the capacitors are dimensioned for currents of up to 100 A. The ESL values range from 35 to 80 nH (capacitors with ESL values of less than 20 nH are available upon request).

Thanks to the polyurethane filling, the windings have a high mechanical stability within the hermetically sealed can. The capacitors comply with climate class C and pass a THB test (temperature, humidity, bias) at 85°C, 85% relative humidity with a rated voltage applied for 1000 hours. Condensation up to a certain level on the capacitors during operation is also permissible. In addition, the power capacitors meet all requirements concerning fire protection in rail vehicles according to EN 45545.

Thanks to their robustness and high rated voltages, these capacitors are particularly suitable for IGBT-based converters in traction applications, as well as medium-voltage drives.
