Magnetic Permeability of Ferrite Material

Inꢀorderꢀtoꢀachieveꢀmostꢀeﬃcientꢀnoiseꢀreduction,ꢀitꢀisꢀimportantꢀtoꢀselectꢀtheꢀmaterialꢀaccordingꢀtoꢀtheꢀtargetꢀfrequencyꢀ

band.ꢀDependingꢀonꢀitsꢀmagneticꢀpermeability,ꢀaꢀparticularꢀferriteꢀmaterialꢀwillꢀbeꢀeffectiveꢀinꢀaꢀcertainꢀfrequencyꢀband.

Aꢀschematicꢀrepresentationꢀofꢀtheꢀrelationshipꢀbetweenꢀtheꢀmagneticꢀpermeabilityꢀofꢀeachꢀmaterialꢀandꢀtheꢀcorrespondingꢀ

effectiveꢀbandꢀrangeꢀisꢀshownꢀinꢀFigureꢀ1.ꢀMaterialsꢀwithꢀhigherꢀmagneticꢀpermeabilityꢀareꢀeffectiveꢀinꢀtheꢀlowerꢀfrequencyꢀ

range,ꢀwhileꢀthoseꢀwithꢀlowerꢀmagneticꢀpermeabilityꢀareꢀeffectiveꢀinꢀtheꢀhigherꢀfrequencyꢀrange.ꢀThus,ꢀMn-Znꢀproductsꢀareꢀ

mainlyꢀusedꢀforꢀreducingꢀconductionꢀnoise,ꢀwhileꢀNi-Znꢀproductsꢀareꢀcommonlyꢀusedꢀforꢀradiationꢀnoiseꢀcountermeasures.

Theꢀeffectiveꢀfrequencyꢀrangeꢀvariesꢀdependingꢀonꢀcoreꢀshape,ꢀsizeꢀandꢀnumberꢀofꢀwindings.ꢀThisꢀfrequencyꢀdependenceꢀ

ofꢀtheꢀmagneticꢀpermeabilityꢀasꢀshownꢀinꢀtheꢀﬁgureꢀservesꢀforꢀreferenceꢀpurposesꢀonlyꢀandꢀitꢀshouldꢀbeꢀtestedꢀonꢀtheꢀactualꢀ

S18H, S15H, 10H, 7H, 5H, 1400L and 700L are KEMET’s proprietary ferrite material names. Other materials can also be

available on request.
