The low radiated noise characteristic of Shielded inductor is one of its significant advantages. The realization of this characteristic mainly relies on its unique design and construction.
First, the Shielded inductor adopts a magnetic shielding structure, which can effectively reduce the impact of the magnetic field generated by the inductor on the surrounding environment. Specifically, the magnetic shielding structure can absorb and disperse the magnetic field generated by the inductor, reducing the radiation intensity of the magnetic field, thereby reducing the radiation noise of the inductor.
Secondly, Shielded inductor also uses high-quality materials and manufacturing processes. The selection of these materials and processes allows the inductor itself to have better electrical performance and lower resistance, thereby reducing thermal noise and resistive noise generated when current flows inside the inductor. At the same time, high-quality materials and manufacturing processes can also ensure the stability and reliability of the inductor, further reducing the noise level of the inductor.
In addition, Shielded inductor also reduces noise by optimizing circuit design and wiring methods. In circuit design, the coupling and interference between signal lines can be reduced through reasonable layout and wiring, thereby reducing the transmission of noise. At the same time, technologies such as differential amplification circuits can also be used to further improve the anti-interference ability of the signal and further reduce the impact of noise.
To sum up, the low radiation noise characteristics of Shielded inductor are achieved through various means such as magnetic shielding structure, high-quality materials and manufacturing processes, as well as optimized circuit design and wiring methods. These measures can effectively reduce the noise level of the inductor and improve the stability and reliability of the circuit, making Shielded inductor widely used in various electronic equipment.
