Overview
The KEMET ESD-SR Series snap-on toroidal cores are
designedforuseonroundcables.Thewiderangeof
ManganeseZinc(MnZn)andNickelZinc(NiZn)options
allowsfortargetingofspecificfrequencyranges.
EMI cores are part of a family of passive components which
addresstheissuesofnoiseorelectromagneticinterference
(EMI)incircuitsorsystems.
Applications
Consumer electronics
• Airconditioners
• Power conditioners
• Refrigerators
• Washingmachines
• Industrialequipment
• Medicalequipment

Turns and Impedance Characteristics
WhenthedesiredperformanceofanEMIcorecannotbe
obtainedwithasinglepassthroughthecore,theimpedance
characteristicscanbechangedwithmultipleturns.
Aturniscountedbythenumberoflead-wirewindingswhichpass
throughtheinnerholeofthecore.Windingsontheoutsideofthe
core do not count.
SeeFigure1forexamplesofone,two,andthreeturns.
Addingturnswillresultinhigherimpedancewhilealsolowering
theeffectivefrequencyrange.
SeeFigure2foranexample.
Core Material and Effective Frequency
Range
There are two ferrite material options for KEMET
EMICores:NickelZinc(Ni-Zn)andManganese
Zinc(Mn-Zn).Eachcorematerialhasadifferent
resistanceandeffectivefrequencyrange.The
MnZn core material has a lower resistance
comparedtotheNi-Zn;therefore,adequate
insulationisrequiredbeforeuse.
TheNi-Zncorematerialistypicallyeffective
forfrequenciesintheMHzbandrangesuchas
theFM-band,whiletheMn-Zncorematerialis
typicallyeffectiveforthekHzbandrangesuchas
theAM-band.SeeFigure3.
It is recommended to measure the actual
frequencyrangeeffectivenessinthetarget
application.

Magnetic Permeability of Ferrite Material
Inordertoachievemostefficient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figure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.
Othermaterialscanalsobeavailableonrequest.

Handling Precautions
EMICoresshouldbestoredinnormalworkingenvironments.WhiletheEMICoresthemselvesarequiterobustinother
environments,avoidexposuretohightemperatures,highhumidity,corrosiveatmospheresandlongtermstorageforcase,
snap-on and split types.
KEMETrecommendsthatmaximumstoragetemperaturenotexceed40°Candmaximumstoragehumiditynotexceed75%
relativehumidity.Atmospheresshouldbefreeofchlorine,sulfurandalkalibearingcompounds.Avoidalsostoragenear
strongmagneticfieldsasthismightmagnetizetheproduct.
Temperaturefluctuationsshouldbeminimizedtoavoidcondensationorcracksontheparts.Mechanicalshockscanbring
to cracks as well.
Export Control
For customers in Japan
Forproductsthatarecontrolleditemssubjecttothe“ForeignExchangeandForeignTradeLaw”ofJapan,theexportlicense
specifiedbythelawisrequiredforexport.
For customers outside Japan
EMICoreproductsshouldnotbeusedorsoldforuseinthedevelopment,production,stockpilingorutilizationofany
conventionalweaponsormass-destructiveweapons(nuclearweapons,chemicalorbiologicalweapons,ormissiles),orany
other weapons.
