NOISE REMOVAL FILTER AND MANUFACTURING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a noise removal filter capable of improving performance and reliability by improving impedance characteristics by successfully maintaining bondability, insulation properties, and withstand voltage characteristics and the like of an upper magnetic body and enhancing magnetic permeability, and a manufacturing method therefor.

SOLUTION: A noise removal filter 100 comprises: a lower magnetic body 110; an insulating layer 120 provided on the lower magnetic body and having at least one conductor pattern 121 or 122; input/output stud terminals 141a and 142a electrically connected to a conductor pattern for electrical input and output of the conductor pattern; and an upper magnetic body having an inner upper magnetic body 131 including ferrite powder of a size corresponding to the interval between the input/output stud terminals and an outer upper magnetic body 132 including ferrite powder of a size corresponding to the interval between the input/output stud terminals and an outside surface of the lower magnetic body.
