This product guide introduces the CORCOM series highest performance RFI filters, which are specifically designed for switching power supplies and are intended to provide all the power line filtering needed to control conducted emissions all the way down to 10kHz.
The document describes the CORCOM Q Series of RFI power line filters designed specifically for switching power supplies. These filters are engineered to control conducted emissions from 10 kHz up to high frequencies, providing high attenuation for both common mode and differential mode interference without performance degradation under large peak currents.
Two primary model series are detailed: the EQ models, which meet low leakage current requirements for VDE portable equipment and UL544 non-patient medical applications; and the VQ models, which offer higher common mode performance suitable for UL, CSA, and VDE non-portable equipment. The document provides specific electrical specifications including maximum leakage currents, hipot ratings, operating frequencies, and insertion loss data across various current ratings.
