COIL COPING WITH NARROW DEVIATION

Title:

COIL COPING WITH NARROW DEVIATION

Document Type and Number:

Japanese Patent JP2006196639

Kind Code:

A

Abstract:

To provide an inductor capable of coping with narrow deviations with a small size and low cost, while being a fixed type coil.

A 3-terminal face connection electrode 2 is mounted on a bottom surface of a drum core 1, having three flanges. A first coil C1 of a predetermined number of times of winding, is wound as preliminary winding at a lower side of two winding grooves partitioned by upper and lower flanges 11, 12 of the drum core 1 and an intermediate flange 13 of the same, and a second coil C2 is wound with the number of times of winding arranged, in response to an L value of the preliminary winding as correction winding at an upper side of the winding groove. Such a constitution deals with the narrow deviation taking, as an L value, synthetic inductance of two coils C1, C2.
