Product Description
Shielding mechanism:
Utilizing the phenomenon of electromagnetic induction(Under the action of external alternating magnetic field)
-Induced current occurs in the shielded shell
-Produce an electromagnetic field in the opposite direction to the external electromagnetic field
-Offsets the impact of external electromagnetic fields on the circuit inside the shielded body
-Achieved shielding effect
