For compact frequency converters in the power class up to about 40 kW, Epcos now has space-saving MKP link circuit capacitors of the DC Link HD series (B3277) with a high capacitance density.
The self-healing capacitors cover the voltage range from 450 to 1300 DC and are available with capacitance values of between 1.5 and 110 µF.
With their low ESR of down to 3.0 mΩ and small ESL of 10 nH, they offer a ripple current capability of up to 20 A at 70 °C and 10 kHz.
The DC link hp series (B3267) is optimised for high power densities. It is designed for voltages between 450 and 1050 DC and offers capacitance values between 0.47 and 60 µF. The capacitors feature a high ripple current capability of up to 23 A.
Both series are designed for a service life of 200,000 h and can be operated at a temperature of up to 105 °C. Four-pin versions are also available for applications requiring increased vibration stability.
