Requirements for capacitors being used in the DC/DC converter include very high reliability, vibration resistance, excellent current handling capability, and low ESR. For this application, EPCOS offers two different series, the first is the standard polyester or the MKT B3252. The normal capacitance value required for this position is from 5 to 220µF and the voltage is up to 400 VDC. The other type offered is the DC Link which was discussed on the previous slides. Different lead configurations are available for these types, two pin, four pin, or multi-pin and even flat terminals in some cases. Both of these series offer low ESR at high frequencies and high current capabilities.
