PURPOSE:To constitute a ringing eliminating device so that it can be handled as a miniature transformer and to fixedly provide it on a circuit board of a television set. CONSTITUTION:A ringing eliminating device 8 is constituted by matching a pair of E type cores 10, fitting and installing a coil bobbin 11 to a central magnetic leg, and winding round and forming separately a first coil winding 12 and a second coil winding 13 to this coil bobbin 11. In a terminal fitting part 16 of the coil bobbin 11, a terminal 17 is provided projectingly toward the lower part, and by utilizing this terminal 17, the ringing eliminating device 8 is connected and fixed to a circuit board 5 of a television set. To a first coil winding 12, an input current of a deflecting coil is allowed to flow, and to a second coil winding 13, an output current of the deflecting coil is allowed to flow, magnetic fields generated by the respective coil windings 12, 13 are opposite to each other and negated, and influence of a higher harmonic which gets on a deflecting current is eliminated. |
