The magnetic ring and the connecting cable form an inductor, which is a commonly used anti-interference component in electronic circuits. It has a good shielding effect on high frequency noise, so it is called an absorption magnetic ring. Because it is usually made of ferrite material, it is also called…

Ceramic tubes are insulating, high temperature resistant, waterproof and wear resistant, and are suitable for use as external protective materials at the branching of wires. When it comes to the protection of these key parts of the wires, the quality of ceramic tubes must be well controlled to avoid casualties…
