With the launch of the iPhone 8 that supports wireless charging, the development of the wireless charging industry is in full swing, and more and more wireless charging products have entered people's lives. Today we are mainly talking about the wireless charging ferrite magnetic separator, as shown in the figure below.
There are two main types of magnetic separators
1. Hard magnetic sheet: The ferrite sheet sintered at high temperature has high magnetic permeability, and the material is hard and easy to crack. It is often used in the transmitter of wireless charging.
2. 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.
So what is the main role of ferrite magnetic separators in wireless charging products? Why use it?
In general, the magnetic isolation sheet mainly has the functions of magnetic conduction, magnetic blocking and heat conduction.
What are the main specifications of ferrite magnetic isolation sheets?
The ferrite magnetic isolation sheet is mainly a round sheet, a circular ring sheet, the thickness is usually 1mm, such as D50*1, D30*5*1D, etc., which are relatively thin.
