3M™ Flux Field Directional Materials RFIC Series
Product Description
3M™ Flux Field Directional Materials (FFDM) RFIC Series are magnetic sheets for radio frequency application.
3M FFDM RFIC series is designed to have a high magnetic permeability and low magnetic loss over 1MHz. These
products help solve the metal interference effect of tag and reader when metal surrounds the atmosphere.
3M FFDM RFIC series includes product numbers RFIC10, RFIC15, RFIC20, RFIC25, and RFIC30 and is available in sheets.
Standard size is 210mm x 297mm.
Features and Benefits
• Minimizes the occurrence of eddy currents in localized metalized surfaces that can reduce the associated
antenna performance
• Makes it possible to mount the antenna on metal surfaces
• Helps solve the metal interference effect of tag and reader when the antenna is on or near metal surfaces
• Consists of dark color magnetic material layer and pressure-sensitive adhesive
Applications
3M FFDM RFIC series is typically used for the 13.56MHz NFC antenna tag or reader applications. 3M FFDM RFIC series
is normally attached to the NFC antenna and positioned between the antenna and the metal or other conductive surface
that the antenna/FFDM is attached to. By inserting the 3M FFDM RFIC series between the antenna and conductor
surface, it is possible to significantly limit occurrences of eddy current and correct for resonant frequency shifts to
the antenna, which are caused by the interaction of the antenna and the conductor surface (i.e. metal surface).
An NFC antenna near a metal surface can induce eddy currents in the metal surface, which in turn can degrade the
antenna performance for read range. 3M FFDM RFIC series redirects the flux field of the antenna away from the metal
surface and limits the eddy current generation and associated negative performance impact.
RFIC Effectiveness
Many factors determine the true communication range such as antenna size, sensitivity, field intensity, modulation
algorithm and environment. To maximize the performance, it is necessary to take into account the fact that the
inductance of the antenna may be changed by 3M FFDM RFIC series. It is necessary to adjust the resonance
frequency of the antenna and circuit by changing the circuit capacitance and inductance value to be optimized with
the FFDM addition.
