Pulse transformer
First Claim
1. A pulse transformer, comprising:
- a drum core having a winding core, a first flange provided at one end of the winding core in a first direction, and a second flange provided at an other end of the winding core in the first direction;
first, second, third, and fourth terminal electrodes provided on the first flange;
fifth, sixth, seventh, and eighth terminal electrodes provided on the second flange; and
first, second, third, and fourth wires each having one end connected to a different one of the first to fourth terminal electrodes and an other end connected to a different one of the fifth to eighth terminal electrodes,wherein a length of the drum core in the first direction and a length of the drum core in a second direction perpendicular to the first direction are substantially equal to one another, such that a planar shape of a mounting region of the pulse transformer is substantially square,wherein the pulse transformer further comprises a plate core fixed to the first flange and the second flange in a third direction perpendicular to the first and second directions,wherein the plate core has a square outer shape as viewed from the third direction,wherein each of the first flange and the second flange has a first surface extending in the first and second directions,wherein the first surface has a lower area and an upper area protruding from the lower area, andwherein each of the first to eighth terminal electrodes has a first section covering the upper surface of the first surface.

Abstract
A pulse transformer includes a drum core having a winding core, a first flange provided at one end of the winding core in a first direction, and a second flange provided at the other end of the winding core in the first direction. First, second, third, and fourth terminal electrodes are provided in the first flange, and fifth, sixth, seventh, and eighth terminal electrodes are provided in the second flange. First, second, third, and fourth wires each have one end connected to a different one of the first to fourth terminal electrodes and the other end connected to a different one of the fifth to eighth terminal electrodes. A length of the drum core in the first direction and the second direction, perpendicular to the first direction, are substantially equal to one another, such that a planar shape of a mounting region of the pulse transformer is substantially square.
