Abstract
A noise eliminating filter is incorporated in the circuits of electronic equipment to eliminate unwanted signals by grounding such signals. The filter includes a tubular metal casing, capacitors and a magnetic material housed within the casing, and a terminal passing through the capacitors and magnetic material. Capacitor housings are provided at both axial ends of the metal casing. A magnetic material housing which is smaller in diameter than each capacitor housing is formed between the capacitor housings and a feedthrough terminal is inserted through the capacitors contained in both the capacitor housings and the magnetic material contained in the magnetic material housing. The capacitors, which are to be incorporated in the housings at both end portions of the casing are made tubular and equal in diameter, thereby enabling the metal casing to be compact and enabling the capacitors to be standardized.
