Development and classification of flat magnetic rings
Edit:Dongguan Yufu Magnetic Material Technology Co., Ltd.   PublicDate:2019-05-14

If the flat magnetic ring is not the same frequency, the impedance characteristics will be different. In most cases, when the frequency is relatively small, the impedance will be smaller. If the frequency is increased, its impedance will rise immediately.


Many people know that if the signal frequency of the flat magnetic ring is higher, it will be easier to radiate. When purchasing a computer case, the quality should be better. The reason is to reduce the electromagnetic leakage. However, ordinary signal lines are not shielded. These signal lines are very good antennas. They will receive high-frequency signals of various noises in the vicinity, but these signals are overlapped with the original transmission signals. At that time, it may change the original useful transmission signal. After using the flat magnetic ring, some useful signals can be passed smoothly, and high-frequency interference signals can be avoided, and its cost is relatively small.


The application of the flat magnetic ring , effective classification of the signal, control of the impedance, is very effective for the treatment of high frequency noise, and promotes the development of the electromagnetic industry.

Dongguan Yufu Magnetic Material Technology Co., Ltd. was established in December 2005. The company is committed to the research, development, production and sales of soft ferrite materials. Now it has a complete set of advanced production equipment, scientific research technology and effective management. The system is a solid foundation for expanding the market.


Soft ferrite materials have been widely used in the electronics industry because of the high surface impedance and low eddy current loss of soft ferrite, which is superior to metal materials in high and low frequency magnetic fields. Such a magnetic core can be used according to different circuit requirements and operating frequencies, so that the component body made of the soft ferrite is used in wired or wireless communication equipment, instrumentation, household appliances, and the like.


When a soft ferrite core is found to be effective in preventing glitch noise, it also attenuates high frequency noise and suppresses interference from the system or interference between the system and the system, and is designed in different circuits. Various types of magnetic core products are anti-interference filter components, components for frequency modulation and modulation, components for transmitting signals, components for inductive filters, components for adjustable linear inductors, etc., so that various magnetic core electronic components are actually It is used in the circuit. However, after the magnetic core component absorbs the harmonic harmonics of each electronic component in the circuit, it is transferred by heat, so that no energy loss occurs even if there is a conductive object in the vicinity of each electronic component body in the whole circuit. Finally, it has an anti-interference inhibition effect.
