EMI Filtering

Filtering is a measure used to supress "conducted noise", which is transmitted through cables and transmission lines.
One of the simple implementations of this solution is to mount ferrite cores around cables to pass only low frequency band signals and attenuate
high frequency conducted noise in cables.

Split Ferrites High performance nickel zinc split ferrites, effective against high frequency noise. Designed to reduce cost and time to market saving. Ranges available: GRFC, SFC, GTRCN, KCF, TFC, TFCM, TFCK, TFCR, TRCA.
Flat Cable Ferrites High performance nickel zinc range of flat cable ferrites. Superior suppression of radiation emissions for full compliance with FCC, VDE and VCCI on Interface / data line Ribbon/FPC cables of computers, peripheral/terminal equipment. Ranges available: GFPC, GSSC, GSSH, GFPH, GFPO, FFPC, BCN, EFC, FP
Round Ferrite Cores High performance nickel zinc range of round ferrite cores. Typically wound with two or three turns of a cable. The impedance ratio is actually proportional to the square of the turn. Ranges available: RI, TR.
Wound Beads Ferrite beads are used to remove high frequency noise. Noise suppression of on-board components of personal computer work, word processor, facsimile and other digital equipment. Ranges available: RH, R6H
Ferrite Plates EMI suppression is achieved by simply inserting the D-Sub plate on the pins of the connector. Space savings is achieved due to being integrated in the connector. Ranges available: FH
Finemet Cores Toroidal cores employing FINEMET, nanocrystalline soft magnetic material. High impedance can be obtained in MHz frequency band and under. Ranges available: F series.
Oval Cores High performance nickel zinc range of oval ferrite cores. Typically wound with two or three turns of a cable. The impedance ratio is actually proportional to the square of the turn. Ranges available: GTRE
Low Cut Cores High impedance character showed in low frequency noise. Reduce damage by load to the cable due to R shape of ridge coated with epoxy. Ranges available: TRM
Absorbing Sheets Highly flexible electromagnetic wave absorbing sheet, bend-resistant and thin type suitable for CPU, round cable and chassis to reduce EMI noise. Ranges available: MG
