Coil component
A coil component that can be mounted on a printed circuit board, with a part in an aperture of the printed circuit board. The coil component includes a first flange on an upper side and a second flange. Terminal boards are on respective opposite sides of the first flange. Terminals respectively project in a direction perpendicular to an axial direction of a winding drum, from the terminal boards and bend and are inserted into through-holes of the printed circuit board. First and second touching surfaces, which are parts of a downside surface of the second flange, touch an upside surface of the printed circuit board.
1. A coil component comprising:
a bobbin including a winding drum, first and second flanges on respective opposite sides of the winding drum, a terminal board on the first flange, and a terminal projecting from the terminal board;
a winding on the winding drum of the bobbin and having an end electrically connected to the terminal; and
a magnetic core having a central leg inserted into the bobbin and a side leg surrounding the bobbin, wherein
the coil component can be mounted on a printed circuit board, with a part of the coil component in an aperture of the printed circuit board, and
when a mounting-direction of the coil component is defined as a downward direction and the first flange is on an upper side compared with the second flange, the terminal extends downward and is inserted into a through-hole of the printed circuit board, and a downside surface of the second flange partly touches an upside surface of the printed circuit board.
2. The coil component according to claim 1 , comprising a
first touching surface including a first portion, which is a part of an edge of the second flange, and
a second touching surface including a second portion, which is a part of an edge of the second flange, and which is on an opposite side of the first portion, wherein the first and second touching surfaces touch the upside surface of the printed circuit board.
3. The coil component according to claim 1 , wherein
the terminal is an L-shaped pin terminal.
4. The coil component according to claim 1 , wherein the magnetic core includes a first core which is an E-shaped core and a second core which is one of an E-shaped core and an I-shaped core, and
the central leg of the E-shaped core is inserted into the bobbin.
