The WCNFC121009/DS Series from Sumida is a DC Common Mode Choke Coil that is ideal for high-speed differential signal lines (USB, HDMI, Ethernet), audio lines, power line noise filtering, and LAN modules. They have a common mode impedance of up to 300 ohms and an impedance tolerance of ±25%. These inductors have a rated voltage of 20 V and a dynamic contact resistance (DCR) of up to 495 milli-ohms. They offer the best EMI suppression effect and high self-resonance frequency, which enables a high cut-off frequency. These wound chip structured inductors have an insulation resistance of 10 milli-ohms and a temperature rise current of up to 800 mA. These RoHS-compliant inductors are available in a surface-mount package that measures 1.4 x 1.2 x 0.9 mm.
