Abstract

An EMI bead core filter to suppress noise has an impedance which increases with frequency, and comprises a ferrite core 3, a wire 7 and an epoxy powder coating layer P. The layer is deposited on the upper portion of the core 3 and on a bend portion 8 of the wire to adhere the core and the wire. The filter is produced by bending the wire 7 and then inserting it into the core 3 to form a prefilter 1' which is supported on a tape 11, 13. The portion 8 of the prefilter 1' is then heated and coated with epoxy powder from a chamber 27. The filter is then packaged and hardened. The coating is accomplished by heating at 380 DEG C initially, and then at 335 DEG C to 340 DEG C for three more times. <IMAGE>
