  • Publication number: 20220359116
    Abstract: An electronic circuit includes a shield line including first and second signal lines and a shield. The first and second signal lines are connected to a signal source, and the shield coating is around the first and second signal lines. The electronic circuit further includes a signal ground near the signal source; a frame ground that is isolated from the signal ground and connected to the shield; a common mode choke coil that includes first, second and third coils magnetically coupled to one another; and a capacitor that is connected in parallel with the third coil. The first coil is connected in series between the signal source and the first signal line. The second coil is connected in series between the signal source and the second signal line. The third coil and the capacitor that are connected in parallel are connected between the signal ground and the frame ground.

  • Patent number: 9865388
    Abstract: An electronic component includes a main body formed from an insulative material, coil conductors, outer electrodes provided on a surface of the main body, and outer pads. Each coil conductor is constituted by a spiral-shaped coil portion and a lead portion connected to the coil portion and extending linearly. The outer pads connect the lead portions to the outer electrodes. At a contact point that connects one of the coil portions to their corresponding one of the lead portions, an angle formed by the coil portion and the lead portion is an obtuse angle.

  • Patent number: 9431163
    Abstract: A transformer includes a first coil spiraling inwardly in a second direction. A second coil spirals along the first coil on the outside relative to the first coil. First and second external electrodes are provided in third and fourth directions relative to a first line passing through a gravity center of the first coil and an outer end thereof, respectively, the third direction being perpendicular to the first line, and the fourth direction being opposite thereto. First and second lead-out conductors are connected to the outer end of the first and the second coil, respectively, and electrically connected to the first and the second external electrodes, respectively. Both coils spiral along each other throughout their lengths. By spiraling in the second direction, the first coil is, at the outer end, oriented in a fourth direction.
