Specifications
FLEX SUPPRESSOR® is a composite magnetic body in the form of sheet made
by blending and dispersing micron sized magnetic material powders in a
polymer base, and a sheet type noise suppressor effectively suppressing high
frequency noise generated from electronic devices.
Features
●High permeability achieves high noise suppression effect
　even if it is thin.
●Flexible sheet type noise suppressor.
●It can suppress noise just put on only.
●Easy to process a shape.
●Best suits for thin devices with the limitation of the space.
●Usable in a wide range from MHz band to GHz band.
Applications
●Radiation noise suppression in all kinds of electronic equipment.
●Measures for the desense LTE, Wi-Fi, GPS, etc.
●Malfunction prevention of ESD (Electro Static Discharge).
●Magnetic material for Wireless power transfer.
●High Permeability type ●GHz band High Performance type

An EMI suppressor sheet that insures
clean electromagnetic environments.
The secret of FLEX SUPPRESSOR an EMI suppressor-lies in its structure,
where ultra-thin magnetic metal foils on the micron order overlap each other
in the same direction. Because of this unique configuration, FLEX SUPPRESSOR
can suppress noise at a level surpassing that of ferrite-based devices.
FLEX SUPPRESSOR absorbs harmful　noises and
converts them into heat to create clean electromagnetic environments.

hile transmitted waves can be minimized,
most of the incoming waves are reected,
causing internal interference.
High-freuency elec t ric current occurs on the
metal surfaces and reected noise occurs at
the shielding oints, metal openings,
and other parts when the grounding is poor.
Shielding materials
(metal, electrically conductive material)
To prevent reection,
electromagnetic energy is
absorbed and converted
into heat.
Shielding material + Radio wave
absorber Transmitted waves and
reected waves can be minimized
by mounting metal plates on the
back of radio wave absorbers.

Handling precautions
Avoid high-temperature, humidity and direct sunlight. Storage
environment should be below 40C and below 70% relative
humidity.
The surface resistance value listed in this catalog is a reference
value of the circuit parameter to indicate noise suppression. The value
does not mean the product's insulation characteristics. The value may
become lower if an excess pressure is applied to the product.
Products in this catalog are not insulators. Please handle them as
conductors. When in actual use, please be careful so that
conductive material does not contact the surface or the edge of
FLEX SUPPRESSOR® sheet. Insulation process should be
performed when contact to conductive material is probable.
Depending upon the processing procedure, powdery substance
may drop out from sheet surface or edge if the cutting of the
sheet is performed at the customer side. Please be careful as
this powder may effect the component's performance
depending on the location.
Clean away any dust, oil or moisture from the surface of the
installing area when attaching the sheet using adhesive tape.
Handling of the products
The manufacturer's warranty will not cover any disadvantage or
damage caused by improper use of the products that deviates from
the char acteristics, specifications, or cond itions for use descr ibed
in this catalog.
The products in this catalog are intended for use in ordinary
electronic products. We withhold the selling of the products if any
of them are to be used in special applications requiring extremely
high reliability where product defects might pose a safety risk and
human life.
Though the manufacturer has taken all possible precautions to
ensure the quality and reliability of its products, improper use of
products may result in bodily injury, fire, or similar accident. If you
have any questions regarding the use of the products in question,
please consult your TOKIN sales representatives.
Please be advised that the manufacturer accepts no responsibility
for any infraction by users of the manufacturer's products on third
party patents or industrial copyrights. The manufacturer is
responsible only when such infractions are attributable to the
structural design of the product and its manufacturing process.
Export Control
For customers outside Japan
TOKIN 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.
For customers in Japan
For products which 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.
