SF-series filters by OnFilter Inc. 

OnFILTER’s SF-series filters substantially reduce high-frequency leakage currents in pulsh width modulation (PWM) motors and in wiring, assisting in compliance with the requirements of IEC60034-17/-25. They also reduce interfering high-frequency noise within the tool resulting from PWM-driven motor operation. Filters outperform conventional reactors by reducing ground EMI currents by the factor of 20 or more. OnFILTER‘ SF series filters have no mechanical coupling to the motors — all connections are electrical. Their cost of ownership of maintenance-free SF series filters is zero. SF series filters are rated 3 to 20 A up to 250 V. The filters carry ETL and CE approvals and are RoHS compliant.
