Abstract: Disclosed herein is a coil component that includes a base, a metal wire that is wound around the base and contains copper, and a terminal electrode that is provided on the base and contains nickel and tin. The terminal electrode includes a wire connection area to which an end portion of the metal wire is connected and which contains a CuNi alloy or a CuNiSn alloy, and a mounting area which is different from the wire connection area. The wire connection area includes a portion that contains a small amount of tin than the mounting area.

Abstract: 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.

Abstract: A pulse transformer 1 is provided with a drum core 2 including a winding core 3 and first and second flanges 4A and 4B, and wires S1 to S4 wound around the winding core 3. Terminal electrodes P1 and N1 and a center tap CT2 are provided on the flange 4A, and terminal electrodes P2 and N2 and a center tap CT1 are provided on the flange 4B. Each end of the wires S1 to S4 is connected to a corresponding one of the terminal electrodes P1 and N1, the center tap CT2, the terminal electrodes P2 and N2, and the center tap CT1. A length of the drum core 2 in X direction is equal to a length of the drum core 2 in Y direction, so that the shape of the mounting region on the printed circuit board is not changed even after being rotated by 90°.
