Title:
LC COMPOSITE ELEMENT
Document Type and Number:
Japanese Patent JP2007067800
Kind Code:
A
Abstract:

To provide an LC composite element wherein a mount efficiency of an inductor and a capacitor can be improved and the characteristic analysis as a filter can easily executed in comparison with that of a distributed constant type filter.

The inductor L1 and the capacitor C1 are formed by integrally winding first and second belt-like conductors 1, 2 via first and second belt-like dielectric bodies 3, 4. The inductor L1 is formed by winding a first conductor part 11 of the first belt-like conductor 1 on the magnetic core 7, and the capacitor C1 is formed by integrally winding a second conductor part 12 of the first belt-like conductor 1 and the second belt-like conductor 2 in a region outside the inductor L1. While the first and the second belt-like conductors 1, 2 are wound, the inductor L1 and the capacitor C1 are formed at different regions in a radial direction (diametrical direction) to equivalently form a lumped constant type LC filter.
