EMI Absorbing Material

Author:admin   AddTime:2021-05-20

The absorbing material is a kind of soft magnetic flexible ferrite sheet, which has the function of electromagnetic noise suppression, and also has the function of shielding metal interference. The absorbing sheet is mixed with nickel-iron powder and other mixtures, and absorbs It is a sheet-shaped roll made of liquids, such as agents and resins.



The absorber can be repeatedly magnetized in a magnetic field. When the external electric field is removed, most or all of the magnetism obtained will disappear. The principle of the absorber to absorb electromagnetic waves is to use soft magnetic materials in a weak alternating field. On the one hand, it will be magnetized. On the other hand, energy storage, on the other hand, causes B to lag behind H due to various reasons, which is the material absorbs energy from the alternating field and dissipates it in the form of heat energy. It can absorb the noise radiated from communication equipment such as mobile phones, and stick an absorbent on the chip or signal line that emits the noise.

EMI absorbing materials have been applied to our lives and become an indispensable product in our lives.
