Abstract

PURPOSE:To reduce the voltage level of the noise terminal voltage with no deterioration of a spece factor by providing the 3rd winding having an end earthed between two windings of a common mode filter choke. CONSTITUTION:A common mode filter choke contains the 1st the 2nd windings 2a and 2b, and the 3rd winding 3c is provided between both windings 2a and 3b. An end of the winding 3c is kept free with the other end earthed. Thus the area betweeen windings 2a and 2b is shielded electrostatically by the winding 3c. This reduces greatly the level of the noise terminal voltage. Furthermore the space factor is never deteriorated owing to no increase of the number of component parts.
