Distinguish between common and differential mode inductors

How to distinguish between common mode inductors and differential mode inductors?   Common mode inductors and differential mode inductors Common mode inductors and differential mode inductors are one of the effective components against electromagnetic interference, widely used in various filters, switching power supplies and other products, but common mode inductors are used to suppress common mode interference, and differential mode inductors are used to suppress differential mode interference, both are more important filter inductors. Identification of common mode inductors and differential mode inductors Although the two inductors are filter inductors, but the role is not the same to determine the appearance and winding method will be different, for the common mode inductor, it is wound on the same iron core, and the coil diameter and number of coils are the same, but the direction of the opposite, a group of coils have two pins, so the common mode inductor will have 4 pin…
