ABSTRACT:
A miniature surface-mount electronic component which can ensure sufficient impact resistance and vibration resistance especially in an application to a severe use environment such as a vehicle-mounted coil, by putting some contrivance into a method for fixing a coil in a molding process and a method for holding a core and terminals. A miniature surface-mount electronic component including a bar-shaped core2on which a winding wire3is wound, and metal plates5,with an outer casing7made of an insulating resin molded, includes flanges2bsubstantially quadrangular in section at both ends of the bar-shaped core2,and vertical grooves a and b are provided on side surfaces of the flanges2bof the bar-shaped core2as fixing portions for preventing positional displacement occurring when the outer casing7is molded.
