Overview
The KEMET SSHB coils are dual mode chokes with a wide
variety of characteristics. These hybrid coils combine
the two functions of normal mode countermeasure and
common mode noise suppression in just one coil. Reducing
the number of required products ensures cost savings and
spaceeciency.Ourproprietarycorematerialsprovide
optimized solutions for high-temperature requirements
(standard type) or for high permeability needs (R type). In
addition,thespeciallydevelopedshapeisecientwith
normal noise suppression.

Magnetic Permeability of Ferrite Material
Inordertoachieve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 KEMET’s proprietary ferrite material names.
Other materials can also be available on request.

Handling Precautions
Precautions for product storage
AC Line Filters should be stored in normal working environments. While the chokes themselves are quite robust in other
environments,solderabilitywillbedegradedbyexposuretohightemperatures,highhumidity,corrosiveatmospheres,and
long term storage.
KEMETrecommendsthatmaximumstoragetemperaturenotexceed40°Candmaximumstoragehumiditynotexceed70%
relativehumidityandatmospheresshouldbefreeofchlorineandsulfurbearingcompounds.Temperatureuctuations
shouldbeminimizedtoavoidcondensationontheparts.Avoidalsostoragenearstrongmagneticeldsasthismight
magnetize the product.
For optimized solderability, AC Line Filters’ stock should be used promptly, preferably within 6 months of receipt.
Product temperature rise values
The values listed for temperature rise are the result of self-heating in wires when the rated current (commercial frequency)
is applied.
Check and evaluate the value of the core temperature rise under actual operating conditions when using.
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
speciedbythelawisrequiredforexport.
For customers outside Japan
AC Line Filters should not be used or sold for the use in the development, production, stockpiling or utilization of any
conventional weapons, mass-destruction weapons (nuclear, chemical, biological weapons or missiles) or any other
weapons.

Although KEMET designs and manufactures its products to the most stringent quality and safety standards, given the current state of the art, isolated component
failures may still occur. Accordingly, customer applications which require a high degree of reliability or safety should employ suitable designs or other safeguards
(such as installation of protective circuitry or redundancies) in order to ensure that the failure of an electrical component does not result in a risk of personal injury
or property damage.
Although all product–related warnings, cautions and notes must be observed, the customer should not assume that all safety measures are indicted or that other
measures may not be required.
