摘要： A common mode choke coil includes a core, external electrodes, a pair of windings, and a top plate. The core includes a winding core portion and a pair of flanges disposed at respective ends thereof. The external electrodes are provided at lower portions of the flanges. The pair of the windings is wound around the winding core portion of the core, and ends thereof are connected to the external electrodes, respectively. A lower surface and a side surface of the top plate are covered with a metal film and are adhered to upper surfaces of the flanges with an adhesive. Preferably, magnetic powder is mixed in the adhesive.

摘要： A common-mode choke coil includes a core, external electrodes, a pair of wires, and a top plate. The core includes a winding core portion and a pair of flanges at both ends of the winding core portion. The upper surface of the winding core portion and the upper surfaces of the flanges are covered with a metal film. The external electrodes are provided on lower portions of the flanges. A pair of wires are wound on the winding core portion of the core, and the ends of the wires are connected to the external electrodes. The top plate is bonded to the upper surfaces of the flanges preferably via an adhesive.

摘要： A common-mode choke coil has induction immunity characteristics that are improved by a coil structure preventing a transmitter IC and a receiver IC from malfunctioning during an induction immunity test and which controls a decrease in ESD resistance and a decrease in self-resonance frequency. The common-mode choke coil includes a core, external electrodes, a pair of coils, and a top plate. The core includes a core section and a pair of flange sections. The pair of coils are wound around the core section of the core, and the ends of the coils are connected to the external electrodes, respectively. An underside and a side surface of the top plate are plated with a metal film, and bonded to the top surfaces of the flange sections preferably by an adhesive agent. The metal film is segmented into two separate portions so as to define two separate metal sections with a gap therebetween so that the metal sections are electrically disconnected.
