TherearetwoferritematerialoptionsforKEMET
EMICores:Nickel-Zinc(NiZn)andManganese
Zinc(MnZn).Eachcorematerialhasadifferent
resistanceandeffectivefrequencyrange.The
MnZn core material has a lower resistance
comparedtotheNiZn;therefore,adequate
insulationisrequiredbeforeuse.
TheNiZncorematerialistypicallyeffectivefor
frequenciesintheMHzbandrangesuchasthe
FM-band,whiletheMnZncorematerialistypically
effectiveforthekHzbandrangesuchastheAM-
band.SeeFigure1.
It is recommended to measure the actual

Magnetic Permeability of Ferrite Material
Inordertoachievemostecientnoisereduction,itisimportanttoselectthematerialaccordingtothetargetfrequency
band.Dependingonitsmagneticpermeability,aparticularferritematerialwillbeeffectiveinacertainfrequencyband.
Aschematicrepresentationoftherelationshipbetweenthemagneticpermeabilityofeachmaterialandthecorresponding
effectivebandrangeisshowninFigure1.Materialswithhighermagneticpermeabilityareeffectiveinthelowerfrequency
range,whilethosewithlowermagneticpermeabilityareeffectiveinthehigherfrequencyrange.Thus,Mn-Znproductsare
mainlyusedforreducingconductionnoise,whileNi-Znproductsarecommonlyusedforradiationnoisecountermeasures.
Theeffectivefrequencyrangevariesdependingoncoreshape,sizeandnumberofwindings.Thisfrequencydependence
ofthemagneticpermeabilityasshowninthegureservesforreferencepurposesonlyanditshouldbetestedontheactual
devicetodetermineitseffectiveness.
S18H,S15H,10H,7H,5H,1400Land700LareKEMETsproprietaryferritematerialnames.
