Richardson RFPD Inc. has announced the availability and full design support for the metalized polypropylene DC link capacitors from Kendeil. The K31 and K32 series are rated for voltages (VDC) ranging from 0.6-1.3kV and boasts maximum high ripple current of 100A, noted the company.

Both device support temperatures up to 85C can have capacitance range of 120-1000uF. The DC link capacitors are aimed at applications such as solar converters, motor drives, traction, inverters and welding

The primary difference between the K31 and K32 series is that the K31 series is designed for low and medium frequency switching (less than 15kHz), while the K32 series is designed for high frequencies (exceeding 15kHz). Kendeil's K32 series also uses segmented metalized polypropylene, which offers the advantages of controlled capacitance loss and open circuit protection, added the firm.
