Can SUNLORD customize the ferrite sheet shape and size?

SUNLORD can customize the ferrite sheet shape and size according specified case. But in consideration of other factors, such as cost, mass production and delivery time, we recommend our customs choose the ferrite sheet from following PN.


Why ferrite sheet is required in NFC antenna?

When NFC tag clung to a metal surface (eg. Battery surface), the magnetic flux simulated by reader will follow through the metal material, causing eddy-current loss, which would significantly reduce the reading sensitivity and distance. in order to avoid this, a thin ferrite sheet is required between antenna and metal surface. The ferrite sheet will provide a low magneto resistance pathway for flux to improve the reading sensitivity and distance.
