Abstract
A wire wound choke coil uses a metallic conductor to form a coil, the surface of the conductor is pre-plated with metallic material such as gold, silver, nickel, tin or others before covered with an insulation film on it so as to form a plated conductor enclosed with an insulated film. After forming a coil, its two terminals (electrodes) can be directly soldered to a circuit board without extra treatment after stripping off the outer film. The coil leads at two terminals are left a length slightly less than one turn so as to save the time for stripping longer insulation. After that a core with two chamfered or filleted ends, and whose outer diameter being slightly larger than the inner diameter of the coil is inserted longitudinally into the hollow cavity of the coil. By so, the core can be forcibly embraced by the resiliency of the coil without worry of parting accidentally. Besides, both end surfaces of the core are plated so that it can be easily soldered onto the circuit board.
