  • Patent number: 9312061
    Abstract: Disclosed herein is a pulse transformer that includes a drum core having a winding core portion and first and second flange portions, a plate core connected to the first and second flange portions, and a plurality of wires that are wound around the winding core portion. The first and second flange portions and the plate core are ground such that an inductance of the pulse transformer is 350 ?H or more when a bias current of 8 mA is applied to the wires.
    Type: Grant

  • Patent number: 9202620
    Abstract: In a coil component, a shortest distance from a longitudinal wall of a flange portion of a drum core to a wire fixing portion is smaller than a shortest distance of the longitudinal wall to an electrode wire connecting portion by a convex portion formed at the longitudinal wall of the flange portion. That is, since a gap between the flange portion of the drum core and the wire fixing portion is small (or there is no gap), the wire fixing portion can be sufficiently bent. Accordingly, the wire can be securely fixed by a wire fixing portion of a metal terminal.
