How to choose ferrite magnetic ring?
You must first determine the function of the ferrite magnetic ring before purchasing it, such as if the magnetic force needs to be less powerful than that of a NdFeB magnet, whether it can resist infection, whether it can be used for motors or induction sensors, etc.
For instance, if you purchase a ferrite bead to be used inside a power supply, wire, or transformer, you must be aware of its performance indicators, such as its inductance, number of turns, and size.
If you need to be aware of the size, performance, and whether or not they need to be magnetized before delivery when buying ferrite magnetic rings for audio speakers.
If you need to know the magnetization process of the magnetic ring, whether it is multi-pole, tolerance, requirements for magnetic force, etc. when buying ferrite magnetic rings for DC motors or sensors.
Notice：
1. It's simple to use the ferrite magnetic ring. On the cable that needs to be filtered, it is placed directly.
2. Unlike other filtering techniques, it must be grounded, therefore circuit board and structural design are not subject to any additional requirements.
3. It is extremely beneficial for conductors that conduct high-frequency signals because it may be utilized as a common mode choke coil without introducing signal distortion.
