"WebFirst order filters use a single common mode choke and are the least expensive to design vs. higher-order filters. The required inductance value is just the load (in Ohms) divided by the radian frequency (2pi*f) at and above which the signal is to be attenuated, e.g. L=1.99 mH for 4 kHz cut-off into a 50 Ohm load. For a first-order filter ... " - How common mode choke works
