WE-SL Common Mode Line Chokes

Würth Elektronik WE-SL Common Mode Line Chokes are ideal for data lines, power supply systems, USBs, and suppression of common mode noise. The WE-SL series features a two or four winding configuration with high currents up to 2.7A, while the WE-SLM series has ring core technology that results in higher impedances and attenuations. WE-SL1 and WE-SL3 chokes have a low profile, the WE-SL1 has a rated current up to 300mA and the WE-SL3 series offers a trifilar winding style.
