3M Wide Frequency EMI Absorbers (AB) and 3M Flux Field Directional Materials

(FFDM) – Specific Target Application Frequency Range

3M EMI Absorbers (AB) for wide frequency applications:

applied to noisy traces, ICs and reflective surfaces in an enclosure.

3M Flux Field Directional Materials (FFDM): Wireless Power, NFC, Magnetic Shielding Digitizer, and HAC

surfaces by directing the antenna flux fields away from the metal object or surface. 3M FFDM products can also be

beneficial in Wireless Power systems to enhance power transfer efficiency between primary sending and receiving

antenna coils. FFDMs such as EM80KM also are useful as magnetic field shielding materials in a thin format.

Note: Reference EM # # Letter-Letter

(i.e., EM80KM)

- EM = Electro-Magnetic

- # # = Permeability Peak

- 2nd Letter = EM Material Type: M= Magnetic foil,

F = Ferrite, P = Polymer composite

with magnetic fillers.

After EM##LL, the product is identified by

overall thickness in mm (ttt) and one- or

two-sided adhesive (A).

Example: EM45EP @ 0.15 mm thickness with

PSA on one side = EM45EP-ttt-A = EM45EP-015-1

Note that Ferrite Type always has a film on the

non-PSA side.
