Abstract
The present invention provides an LC noise filter consisting of a capacitance and an inductance, including a first insulation sheet having a plurality of portions folded alternately in the opposite directions and stacked one above another; a first conductor applied to the insulation sheet at one side and adapted to form a coil having a given number of turns when the folded portions of the insulation sheet are folded alternately in the opposite directions and stacked one above another; and a second conductor applied to the insulation sheet at the other side and located substantially opposite to the first conductor to form a capacitance therebetween, whereby the filter can eliminate incoming noises without creation of any undesirable phenomenon such as ringing or the like.
Claims13
An LC noise filter comprising:
- an insulation sheet having a plurality of portions folded alternately in opposite directions and stacked one above another;
- an inductive conductor provided on said insulation sheet at a first side to form a coil having a given number of turns when said folded portions are folded alternately in the opposite directions and stacked one above another, said inductive conductor having a predetermined width;
- and
- a capacitive conductor not directly, electrically connected to the inductive conductor and provided on said insulation sheet at a second side, said capacitive conductor having a mirror-image pattern as said inductive conductor to form a sandwich structure around said insulation sheet, said capacitive conductor having a predetermined width providing a capacitance between said inductive conductor and said capacitive conductor.
