Abstract
Disclosed herein is a common mode filter. The common mode filter includes a main body that includes a coil electrode, first and second external electrodes connected with both ends of the coil electrode, respectively, and a ground electrode, and an electro static discharge (ESD) protection layer that includes a switching member formed therein, and is provided on any one surface of the main body. Here, one end of the coil electrode is connected with the second external electrode, the other end thereof is connected with the first external electrode through the switching member, and the switching member is disconnected from the coil electrode in accordance with a switching operation when a surge current is applied and connected with the ground electrode. Therefore, it is possible to protect the common mode filter from a surge current by ESD.
