3M EM13TF FFDM Introduction
The 3M EM13TF is a sintered ferrite sheet designed as a high-efficiency Flux Field Directional Material, with a primary focus on improving wireless power systems. By effectively directing the magnetic flux, it enhances power transfer efficiency between coils. This material can also be used in NFC and RFID applications to de-couple antennas from adjacent metal surfaces.
3M EM13TF FFDM Features:
- High-Efficiency Ferrite: Sintered ferrite sheet construction for superior magnetic performance.
- High Magnetic Permeability: Features a magnetic permeability of 130 at 13.56 MHz.
- Optional Adhesive: Can be supplied with an optional acrylic PSA for ease of assembly.
- Versatile Design: Available in different overall thicknesses to suit specific application needs.
3M EM13TF FFDM Applications:
- Wireless Power Systems: The primary application is to enhance power transfer efficiency and reduce energy loss in wireless chargers (WPC/Qi).
- NFC/RFID Systems: Effectively de-couples antennas from metal interference, preserving signal strength and read range.
- Power Electronics: Can be used for magnetic shielding in various power-related applications.
