The products are mainly classified into absorber sheet, EMI suppressor sheet, sintered ferrite sheet, electromagnetic shielding coating and other electromagnetic functional materials.The product has the characteristics of absorbing and shielding electromagnetic waves, increasing magnetic flux, resisting metal interference and magnetic field isolation.It is widely used in wireless charging module, RFID electronic tag, smart card, NFC module, EMI, EMC and other fields.
Wireless charging ferrites are divided into hard magnetic sheets and soft magnetic sheets. Hard magnetic sheet: ferrite sheet sintered at high temperature, with high magnetic permeability, hard material and easy to crack, commonly used in the transmitter of wireless charging. Soft magnetic sheet: Alloy magnetic powder is added to plastic or rubber, and then processed to form a soft magnetic sheet. The material of the soft magnetic sheet is relatively soft and the thickness is very thin. It can be punched according to the shape and size of the magnetic isolation sheet required by the wireless charging scheme. Wireless charging ferrite mainly has the functions of magnetic conduction, magnetic blocking and heat conduction.
