Conventional noise prevention products focus on somehow minimizing the noise after it s been TM AMOBEADS created, by typically trying to absorb the noise, and so their eectiveness in noise reduction is directly inuenced by frequency of the circuit. Amorphous noise suppressing devices, on the other hand, focus W series on the source of the noise and work to prevent or minimize the noise before it has a chance to develop. 1 2 3 Finished Dimensions mm Core Size mm Total Flux AL value The source of the electronic circuit noise is the rapid change of current or voltage, and the Insulating Packing Type No. O.D. max I.
