Patent ID: 11309859

Abstract:
A noise filter may include: a first conductive line extending between an input and an output terminal portion, wherein the first conductive line includes an input-side conductive line extending between the input terminal portion and a branch portion, and an output-side conductive line extending between the output terminal portion and the branch portion; a second conductive line connected to the branch portion of the first conductive line, wherein a capacitor is on the second conductive line; and a magnetic body surrounding at least a part of a circumference of at least a part of the first conductive line, wherein the magnetic body is configured to magnetically couple the input-side and the output-side conductive lines such that at least an equivalent series inductance of the capacitor and a parasitic inductance of the second conductive line are reduced by a mutual inductance between the input-side conductive line and the output-side conductive line.
