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°. |
