WE-SCC Common Mode Chokes Würth Elektronik WE-SCC Common Mode Chokes deliver up to 160kΩ impedance for common-mode noise rejection thanks to its NiZn core material. Another benefit of this core material is that wide frequency band EMI noise can be suppressed (1MHz to 100MHz). The WE-SCC series is available in three compact case sizes: 7345, 1260, and 1210. Würth WE-SCC Common Mode Chokes are capable of handling currents of up to 4.75A and have a 1:1 turns ratio. They are rated for industrial operating temperatures. Typical applications include suppression of common-mode noise, power supply systems, and data lines.
