    摘要： Disclosed herein is a coil component that includes a drum-shaped core having a first flange part provided at one end of a winding core part, first to fourth terminal metal fittings formed on the first flange part so as to be arranged in this order in a second direction, and first to fourth wires wound around the winding core part. One ends of the first to fourth wires are connected to different ones of the first to fourth terminal metal fittings. A distance between the first and second terminal metal fittings is larger than the distance between the third and fourth terminal metal fittings. An amount of an adhesive used to bond each of the third and fourth terminal metal fittings is greater than an amount of an adhesive used to bond each of the first and second metal fittings.

    摘要： A coil component is provided with a coil, a base supporting the coil having a first surface parallel to an extending direction of the terminal section of the coil, and a terminal electrode having a first terminal portion printed on the first surface of the base. The first surface has a stepped surface including an upper stage surface and a lower stage surface. The first terminal portion has a stepped shape including an upper stage portion formed on the upper stage surface and a lower stage portion formed on the lower stage surface. The upper stage portion has a first terminal surface contacting the terminal section of the coil. The lower stage portion has a second terminal surface positioned on an extension line of the terminal section of the coil and not contacting the terminal section of the coil.

    摘要： A pulse transformer is provided with a drum core including a winding core and first and second flanges, and wires wound around the winding core. First terminal electrodes and a second center tap are provided on the first flange, and second terminal electrodes and a first center tap are provided on the second flange. Each end of the wires is connected to a corresponding one of the first terminal electrodes, the second center tap, the second terminal electrodes, and the first center tap. A length of the drum core in the X direction is equal to a length of the drum core in the Y direction, so that the shape of the mounting region on the printed circuit board is not changed even after being rotated by 90°.
