What the difference between USB cable and the USB cable with ferrite magnetic ring?
The power supply of the USB data cable with magnetic ring and the ordinary USB data cable is the same, both are 5V. Sinodec Industrial Co., LTD. can provide various types of USB data cables according to customer needs, such as Micro USB cable, USB Type-C cable, USB Mini cable, type B and USB lightning cable for iphone. At the same time, it can also provide various types of USB data cables according to customer needs. On demand, provide USB2.0 or USB3.0 Cable.
The magnetic ring is common in various data lines and signal lines. Its function is not to change the power supply of the line, but to improve the performance of data transmission and increase the signal-to-noise ratio. Magnetic ring is a commonly used anti-interference component in electronic circuits, which has a good suppression effect on high frequency noise. The magnetic ring has different impedance characteristics at different frequencies. Generally, the impedance is very small at low frequencies. When the signal frequency increases, the impedance of the magnetic ring increases sharply. Adding a magnetic ring to the circuit without metal shielding layer can well inhibit the passage of high-frequency interference signals, and is low in cost, so it is widely used in display signal lines, USB cables, and even high-end keyboards and mice.
