Abstract:
A coil portion providing a common mode choke coil and a protection element portion providing ESD protection elements are disposed so as to be aligned in a lamination direction of a component body. The ESD protection elements are composed of a ground electrode and discharge electrodes each located so as to be spaced apart from the ground electrode at a predetermined interval. Capacitor electrodes are provided so as to be opposed to the discharge electrodes thereby to form capacitors, and the capacitors and coil conductors of the common mode choke coil form an LC filter. Accordingly, noise removal characteristics are caused to have higher attenuation and a wider band than with a mere inductor.
