Fitting structure for noise filter

Abstract

Abstract PURPOSE:To widen the width of a ground electrode and to improve filter characteristics of the noise filter by rearranging and arraying terminal parts on both sides of a ground conductor part and coating them with insulators, and connecting the electrodes of the noise filter to the terminal parts and the conductor part. CONSTITUTION:The ground conductor 2 and terminals 3a and 3b are arrayed and arranged on the top surface of a substrate 1, and signal conductor paths 4a and 4b are arrayed and arranged on the reverse surface in parallel. The conductors 4a and 4b are connected electrically to the terminals 3a and 3b through a through hole 5. Then the ground conductor part 2a and terminal parts 3a and 3b are provided with the gap 7 of the part of the ground electrode C of a three-terminal capacitor 10 and coated with the insulators 6a and 6b. Then capacitors 10 are arrayed, arranged, and fitted, and the terminal part 3a and a signal electrode A, the terminal part 3b and a signal electrode B, and the conductor part 2a and ground electrode C are connected mutually by using solder 8. Thus, the width of the ground electrode part 2a can be reduced, so the inductance comes to extremely small, and the filter characteristics can be displayed sufficiently.
