Abstract

PURPOSE:To improve withstand voltage property and miniaturize a choke coil by winding two coils onto different winding flutes in a bobbin and by causing distances between the coils and each core of the opposite side thereof to be smaller than specific values, thereby molding around each core and both coils with an insulating resin. CONSTITUTION:Two coils 10a and 10b are wound onto a bobbin 8 and the bobbin gets two C-type cores 4 butted against each other through one side of the C-type cores 4 and they are pressed down by a holding metal fittings 6. Then distances L between both coils 10a and 10b and each core 4 of the opposite side thereof are to be within the range of 0.5-1.2mm. At the bobbin 8, further, four lead terminals 12 protrude downward and a common mode choke coil 20 is formed by connecting both ends of the coils 10a and 10b to the lead terminals 12. And then, with the exception of the lead terminals 12 of the choke coil 20, the whole coil 20 is molded with an insulating resin 22. Thus, the withstand voltage property is improved and insulation distance around the coil is relieved and then the coil can be miniaturized by composing the coil in this way.
