Kind Code:
B2
Abstract:
A manufacturing method for a LC filter (an inductive filter) suitable for use as a noise filter, constituted by the steps of: inserting a central conductor into a cylindrical magnetic substance having electrodes on at least the end faces; dipping the central conductor and magnetic substance into molten solder to solder the electrodes to the central conductor; thereafter inserting the magnetic substance and central conductor into a cylindrical capacitor of a cylindrical dielectric which is provided on the inside and the outside with electrodes and on the outer peripheral surface a cylindrical eyelet member fitted thereon; sealing openings at both ends of the cylindrical capacitor by use of sealing members fitted onto the central conductor after the magnetic substance through which the central conductor passes is inserted into the cylindrical capacitor; then dipping the cylindrical capacitor into molten solder to solder the external electrode and the eyelet member; and remelting the solder for connecting the electrodes on the magnetic substance with the central conductor by the heat applied thereto when the capacitor is dipped into the molten solder, thereby connecting the electrodes on the magnetic substance with the internal electrodes on the cylindrical capacitor to complete the LC filter.
