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:
• 3M EMI Absorbers are used to reduce EMI and RF noise in electronic systems. 3M EMI Absorbers can be
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
• 3M FFDM products are useful for RFID and NFC applications to de-couple the NFC or RFID antenna from metal
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.
