For compact frequency converters in the power class up to 40 kW, Epcos now offers space-saving MKP link circuit capacitors of the DC Link HD series (B3277*) with a high capacitance density. These self-healing capacitors cover the voltage range from 450 to 1300 V d.c. and are available with capacitance values of between 1,5 and 110 μF. With their low ESR of down to 3,0 m and small ESL of 10 nH, they offer ripple current capability 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 V d.c. and offers capacitance values between 0,47 and 60 μF. These capacitors feature high ripple current capability up to 23 A.
Both series are designed for a service life of 200 000 hours and can be operated at a temperature of up to 105°C. Four-pin versions are also available for applications requiring increased vibration stability.
