Abstract:
The present invention discloses a filter for removing noise, which includes: a lower magnetic body; an insulating layer disposed on the lower magnetic body and including at least one conductor pattern; input and output stud terminals electrically connected to the conductor pattern for electrical input and output of the conductor pattern; and an upper magnetic body consisting of an inner upper magnetic body including ferrite powder with a size corresponding to the interval between the input and output stud terminals and an outer upper magnetic body including ferrite powder with a size corresponding to the interval between the input and output stud terminals and an outer surface of the lower magnetic body.According to the present invention, it is possible to implement a coil part with high performance and characteristics by increasing permeability and improving impedance characteristics through simple structure and process.
