Abstract
One object of the present invention is to provide a coil element having a reduced thickness but is less prone to be broken. The coil element according to an embodiment of the present invention has a rectangular parallelepiped shape and has a principal surface including long sides and short sides. The coil element includes a drum core, a winding wound around the drum core, a first external electrode electrically connected to one end of the winding, and a second external electrode electrically connected to the other end of the winding. The drum core in the embodiment includes a first flange, a second flange, and a winding core connecting between the first flange and the second flange. The winding core extends along the short sides of the principal surface.
Claims16
A coil element having a rectangular parallelepiped shape and having a principal surface including long sides and short sides, the coil element being configured for horizontal mounting relative to a mounting surface of circuit board, the coil element comprising:
- a drum core including a first flange, a second flange, and a winding core connecting between the first flange and the second flange, the winding core having a central axis;
- a first winding wound around the winding core and the central axis thereof;
- a first external electrode electrically connected to one end of the first winding;
- and
- a second external electrode electrically connected to the other end of the first winding,
- wherein the central axis of the winding core extends along and parallel to the short sides of the principal surface and in a direction parallel to said mounting surface upon mounting of the coil element,
- wherein the coil element has a height, a width, and a length, the height being a dimension of the coil element in a direction perpendicular to the principal surface, the width being a dimension of the coil element in the direction parallel to the short sides of the principal surface and parallel to the central axis of the winding core, the length being a dimension of the coil element in the direction parallel to the long sides of the principal surface and perpendicular to the central axis of the winding core,
- wherein the width in the direction parallel to the short sides of the principal surface is greater than the height, and the length is greater than the width.
