High current filtering technology - the HPR series

This HPR series of extremely high current filters is ruggedly designed to operate at current levels up to 400 amperes and voltages up to 500 Vdc. A large range of available capacitance provides significant insertion loss at frequencies as low as 1 KHz, and provides over 60 db insertion loss to above 1 GHz. The unique ability to remove high frequency noise from very high current lines makes our patented HPR a proven and economical solution to your high current filter application.
