Definitions
- the reference numeral “11” is used not only for the “first leg” but also for the “ground side input terminal”, and the reference numeral “12” is used for And not only for the “second leg”, but also for the “ground-side output terminal”.
- the noise signal grounded from the ground side output terminal 12 to the ground side output electrode 16 passes through the stray capacitance 19 through the stray capacitance 19 as shown by the dashed arrow 44. It flows to the input electrode 15 and then to the ground-side input terminal 11, which may degrade the noise removing effect.
- the ground side lead wire 31 includes first and second legs 32 and 33 and first and second legs 32 and 33 extending parallel to each other. It is bent into a U-shape as a whole so as to form an intermediate portion 34 connecting one end of each of the portions 32 and 33.
- the reference numeral “28” will be used not only for the “first leg” but also for the “hot-side input terminal”. Also, the reference numeral “29” is used for a “hot-side output terminal” that is not only used for the “second leg”.
- the ground side lead wire 31 is in a state where the first and second legs 32 and 33 extend in a direction parallel to the first and second end surfaces 23 and 24 of the capacitor 22, that is, the hot side.
- the lead 27 extends in a direction parallel to the first and second legs 28 and 29, and is connected to the second terminal electrode 26 at the intermediate portion 34 by soldering.
- the ground lead 31 constitutes a ground input terminal connected to the power supply and a ground output terminal connected to the load circuit side at the first and second legs 32 and 33, respectively.
- the second leg 33 of the ground-side lead wire 31 is connected to the ground plate 39 by soldering. ing.
