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.

Abstract: An electronic component has a laminated body, a circuit element disposed in the laminated body, an electrostatic discharge element disposed in the laminated body, a circuit-element external electrode electrically connecting the electrostatic discharge element and the circuit element, and a grounding external electrode connected to the electrostatic discharge element for electrically connecting the electrostatic discharge element to the ground. The electrostatic discharge element is disposed closer to a first end surface of the laminated body as compared to the circuit element. A height of the grounding external electrode at an end portion closer to the circuit element from the first end surface is lower than a height of the circuit element at an end portion closer to the grounding external electrode from the first end surface.

Abstract: In a multilayer coil component, a multilayer body includes a plurality of insulator layers and a through-hole. The through-hole penetrates in a third positive direction. A first coil extends inside the multilayer body while surrounding an outer circumference of the through-hole. A magnetic resin is filled into the through-hole. An overlying adhesive resin layer is laminated on a first surface of the multilayer body. An upper magnetic substrate is adhered to the multilayer body with the overlying adhesive resin layer interposed therebetween. The overlying adhesive resin layer includes an accommodation space. The accommodation space is connected to the through-hole. When the multilayer coil component is seen in the third positive direction, an outer edge of the accommodation space is located on an outer side of an outer edge of the through-hole. A portion of the magnetic resin is located inside the accommodation space.

Abstract: A composite electronic component includes a main body including insulating layers, first and second input terminals, first and second output terminals, a ground terminal, first and second filters, and a resistance pattern connected between the second filter and the ground terminal. The first filter includes a first coil pattern connected between the first input terminal and the first output terminal, and a second coil pattern connected between the second input terminal and the second output terminal. The first and second coil patterns form a common mode filter. The second filter includes a third coil pattern connected between the first input terminal and the ground terminal, and a fourth coil pattern connected between the second input terminal and the ground terminal. The third and fourth coil pattern form a differential mode filter. The resistance pattern is on the insulating layer different from those of the first to fourth coil patterns.

Abstract: A coil component includes a first magnetic body, an insulator stacked on the first magnetic body, a second magnetic body stacked on the insulator, a coil which is disposed in the insulator and which includes at least one coil conductor layer, and an internal magnetic body disposed within the inner circumference of the coil and connected to the first magnetic body and the second magnetic body. In a cross section in a stacking direction, the width of the internal magnetic body increases continuously from the first magnetic body side toward the second magnetic body side. Also, the inner circumferential surface of an end coil conductor layer located closest to the second magnetic body faces the outer circumferential surface of the internal magnetic body and is inclined in the same direction as the outer circumferential surface of the internal magnetic body with respect to the stacking direction.
