EP21 Flat-Wire Common-Mode Chokes

TDK EP21 Flat-Wire Common-Mode Chokes are flat-wire double chokes designed for common-mode electromagnetic interference (EMI) filtering. These TDK surface-mount (SMD) chokes feature dimensions of 23.8mm length x 17.7mm width and heights of 21.6mm to 22.3mm. The EP21 series also features space-saving underbody termination and a four-pin design for enhanced mechanical reliability. These flat-wire double chokes can handle rated voltages of 48VAC or 80VDC and rated currents of 20.3A to 35A without derating up to +70°C. The TDK EP21 can be used as common-mode chokes for applications such as DC-DC converters or other low-voltage electromagnetic compatibility (EMC) protection circuits.
