  • Winding-type coil component and direct-current superimposing circuit using the same
    Patent number: 11587724
    Abstract: A direct-current superimposing circuit includes differential signal lines, capacitors, a common mode choke coil, a winding-type coil component, and a DC power supply which are disposed at a circuit board. The winding-type coil component includes a core, two pairs of terminal electrodes, and two windings (a first winding and a second winding). On the end surface of a flange portion, the terminal electrodes in one of the two pairs and the terminal electrodes in the other one of the two pairs are placed to face each other across the winding center of a winding core. The winding start and winding end of the first winding are connected to the terminal electrodes in one of the two pairs. The winding start and winding end of the second winding are connected to the terminal electrodes in the other one of the two pairs.
