摘要： PROBLEM TO BE SOLVED: To solve the problem that, since a choke coil used for a DC/DC converter is wound with a conductor as thick as possible for improving conversion efficiency, when the conductor is thick, the choke coil becomes hard to be curved and a dimension of an entangled portion in a height direction becomes large, such that an outer circumference of the entangled portion becomes higher than a mounting portion and it is necessary to enlarge a notch of a ring core for avoiding the entangled portion, and since there are many gaps in the entangled portion, a solder may be stored too much in the gaps in the case of immersion in a solder tub and a solder stab that the solder becomes rectangular may easily occur.SOLUTION: A surface-mounted inductor comprises: a drum-shaped core including a pair of flanges in both ends of a winding shaft; a winding formed by winding an insulation coated conductor around the winding shaft; and a pair of plate-like metal terminals disposed on flange surfaces of the drum-shaped core and including protrusions protruding in outer circumferences of the flanges. A winding terminal is entangled around the protrusions, the protrusions are crushed into a predetermined interval from top and bottom faces, and the entangled portion is then immersed in a solder tub.

摘要： PROBLEM TO BE SOLVED: To solve the problem that when a thermocompression bonding method is applied, a terminal to be bonded is pressure-bonded to an electrode while being pressed thereto after a heater tip is heated to approximately 1,000 degrees, and the state of the tip of the heater tip should always be kept constant by cleaning the tip thereof by polishing or the like since welding strength varies depending on the state of the tip of the heater tip, and the thicker the coil is, the higher pressure is applied by raising the temperature of the heater tip, thus resulting in causing a break or a crack in the core, and the deterioration of the terminal.
SOLUTION: The surface-mounted inductor includes: an air-core coil; a pot-shaped core that has an opening end at a top surface thereof and a square-shaped bottom surface for housing the air-core coil; and a plurality of chamfers that are constituted of platy cores for putting a lid on the opening of the pot-shaped core and has a plurality of lead-out grooves for leading out the coil's terminal at an angular portion of the pot-shaped core.
