Würth Elektronik presents WE-CNSA, an AEC-Q200-qualified common mode choke for automotive applications. The SMT component, which is only two millimeters long and 1.2 millimeters high, is available in six versions with different inductance and impedance values.
WE-CNSA
WE-CNSA provides signal integrity in many applications such as automotive infotainment and communications via FlexRay, IEEE 1394 (Firewire), LVDS, or USB 2.0 and 3.0. The 0805 device features low resistance and a bifilar winding, meaning the two data lines run in parallel around the core. This symmetry improves the suppression of common-mode noise that can couple into data lines.
EMC specialist Würth Elektronik is offering the filter, which achieves high common-mode noise suppression at high frequencies, from stock and is providing free samples to developers.
