Magnetic isolation sheet for wireless charger

Author:admin   AddTime:2021-08-27

As the main material configuration of the wireless charger, the magnetic isolation sheet for wireless charging has become one of the main indicators to measure the quality and performance of a wireless charger module. The wireless charger turns into a sympathetic electromagnetic field from a 220V power supply, and then after the sympathetic electromagnetic field generates a sympathetic electromagnetic field, the sympathetic electromagnetic field turns into a current for charging; when the sympathetic electromagnetic field encounters metal, it will produce electronic eddy current, which will tend to the metal. The skin effect generates heat energy on the metal, which reduces the charging efficiency and wastes electrical energy. And it interferes with the main board of the circuit and affects the normal operation of the whole charger.



The wireless charging module is to isolate the magnetic energy. Its energy is much stronger than the signal. Conceptually, it should be isolated and cannot be absorbed. Once absorbed, the long-term strong electromagnetic wave energy will be converted into heat energy, and the temperature will rise in a short time. Therefore, the wireless charging module used in the mobile phone should pay special attention to the quality of the magnetic isolation sheet. Otherwise, the magnetic leakage of the mobile phone will be serious, and the mobile phone will be easily heated by electromagnetic wave energy, which will affect the charging effect and the life of the mobile phone.
