More Information
Summary:A common mode filter includes: a body including a filter portion; first and second external electrodes each including an electrode layer including conductive particles, intermetallic compound (IMC) formation particles, and a resin, and disposed on an external surface of the body; and first and second coils disposed in the filter portion, the first and second coils being connected through lead portions to the electrode layers of the first and second external electrodes, respectively. The conductive particles include a first conductive particle and a second conductive particle having a diameter smaller than that of the first conductive particle.
