Method of adjusting a characteristic of wire-wound type chip coil by adjusting the space between conductive wires
First Claim
1. A method of adjusting a characteristic of a wire-wound type chip coil comprising the step of:
- providing a wire-wound type chip coil including a core, flanges each having only one terminal electrode respectively disposed on both ends of the core, at least two conductive wires wound around the core, one end of each of the at least two conductive wires being electrically connected to the only one terminal electrode on one of the flanges in parallel, and another end of each of the at least two conductive wires being electrically connected to the only one terminal electrode on another of the flanges in parallel; and
adjusting the space between one of the at least two conductive wires wound around the core and another one of the at least two conductive wires wound around the core so as to adjust the inductance between the terminal electrodes.

Abstract
A wire-wound type chip coil can take various inductance values while maintaining its outer dimension at a specified fixed value. A chip coil is formed by winding at least two conductive wires regularly in a single layer around a core made of a magnetic material and firmly connecting both ends of each conductive wire to terminal electrodes disposed on respective flanges of the core. This makes it possible to obtain a great current capacity. Furthermore, the inductance decreases because of an increase in the magnetic path length. A great number of different inductance values can be easily obtained by properly selecting parameters including the number of substantially parallel conductive wires, the diameter of each conductive wire, and the number of turns.
