How to choose FAM : |
Effect Diagram - Magnetic Shield : |
FAM can change the magnetic flux path to avoid the magnetic flux affect others components. |
Effect Diagram - RFID/NFC on metal : |
The magnetic flux induced eddy current and generated a reverse magnetic field to offset the magnetic flux to cancel the communication. After attached FAM between metal and RFID antenna, the communication will recover. |
Effect Diagram - Wireless Power Charger : |
FAM can be used for wireless power charger to avoid eddy current when RX coil attached on metal and change the magnetic flux path between TX coil, RX coil, magnet. |
Design Kit :
* each item 1 pcs (100x100mm)
