What is the role of electronic components
What is the role of electronic components 1, resistance: its function is to limit the voltage and current through; capacitor: to play the cross-coupling, filtering, isolation through the cross and tuning function.Magnetic Ring Inductor 2, inductor: block AC through DC, block
Switching power supplies use High frequency transformers The reason.
Switching power supplies use High frequency transformers The reason. 1, for safety, regardless of high frequency or low frequency, it is necessary to isolate the high voltage with a transformer. 2, high magnet transformer both from the material and copper wire are very economical, and small volume. 3, silicon steel sheet a material of low frequency transformer, large volume, not economic, only for low fre
What causes the magnetic ring inductor coil to heat up?
Magnetic ring inductor coil heating characteristics: magnetic ring inductor coil is to store energy, suppress electromagnetic interference, through the DC block AC, when the current flowing through the inductor coil is large, the coil will be hot, serious will be hot, the inductance of the inductor will decay, the inductor body surface temperature rises, when the temperature rise of the current exceeds 40 degrees Celsius, the inductor will lose inductive characteristics. In severe cases, the entire PCB board will be burned.
Common mode toroidal inductor winding method with high number of turns
Common mode magnetic ring inductors are wound on both sides of the same number of turns, the same in and out, the number of turns less common mode inductors, line up a layer of general can be completed, this simple here is not introduced, the following is to introduce the number of turns, the middle of the common mode magnetic ring inductors need to be placed in the spacer winding method. The specific process is to tie a tape at each of the symmetrical semicircle of the ring, with the width of the tape slightly l
What are the main applications of magnetic ring common mode inductors?
The higher the magnetic permeability of the magnetic ring inductor, the lower the temperature it can withstand. If the inductance of the magnetic ring inductor is very high, the number of coils wound in the inductor can be reduced, as well as the use of large wire diameter copper wire winding. Choose the right core according to your needs, but the general principles of core selection for magnetic ring inductors remain the same, with the following points. 1, the specifications of the magnetic ring should b
Do you know how to distinguish between laminated inductors and wirewound inductors?
Inductors according to the structure of the main way: laminated inductors and wirewound inductors SMD laminated inductors, ferrite internal production of multi-layer spiral wire laminated inductors, is packaged inside the ferrite multi-layer lines, multi-layer lines form the coil. Laminated inductors are small in size, commonly used materials can be as small as 0201 size, and cheap, suitable for small volume and not demanding scenarios. The main reason for the low requirements is the general accuracy of the laminated inductor, the low Q value, and the small curren
Are magnetic ring inductors easily damaged?
Are magnetic ring inductors easily damaged? Inductive components are not easily damaged. But there are times when they can be damaged. Inductors are easily damaged for the following reasons. 1, core inductor, the core is relatively brittle, there is no external cover, falling to the hard floor, easy to damage the ring, the transport is not well protected from the impact force will also make the core damage.
Magnetic ring inductor manufacturers to explain the four major points of inductor subdivision
Today, I will talk about inductance in detail, let's dissect it bit by bit. A. Self-inductance phenomenon Self-inductance phenomenon: electromagnetic induction phenomenon due to changes in the current of the coil itself. The electric potential generated in the self-inductance phenomenon is called self-inductance electric potential; the current generated is called self-inductance current. Coefficient of self-ind
Magnetic Surround Wire Inductors and SMD Inductors Difference
Magnetic Surround Wire Inductors and SMD Inductors Difference SMD inductors. 1.Surface mount high power inductor. 2, with miniaturization, high quality, high energy storage and low resistance characteristics. 3.Mainly used in computer display boards, notebook computers, pulse memory program design, and DC-DC converters.
What is the purpose of magnetic wire surround inductors?
Wirewound inductors are used in power supply circuits, and the products are widely used in miniature TVs, LCD TVs, cameras, etc. Wirewound Inductor Features 1. Suitable for power supply circuits. 2. Surface bonding type. 3. Appearance and size conform to EIA standard, different size specifications are available.
What are the uses of magnetic ring inductor coils?
The uses of magnetic ring inductor coils can be divided into three categories: choke, filtering, and oscillation. I. Choke Magnetic ring inductor coil in low frequency circuit, is used to stop low frequency AC, pulsating DC to pure DC circuit, it is often used in the middle of two filter capacitors at the output of rectifier circuit, choke and capacitor form Π type filter circuit. In the high-frequency circuit: is to prevent the high-frequency current flow to t
Magnetic ring inductors are actually useful for this purpose
Magnetic ring inductor actually has such a use mention magnetic ring inductor, many people know that it is a common electronic components, the main role is electromagnetic induction conversion, to deal with electronic products appear electromagnetic disturbance and other problems generated. And partners may not understand is the
Magnetic ring inductor application scenarios, what it does
Magnetic ring inductor application scenarios, what it does We all know that an inductor is an electromagnetic induction element made of insulated wire winding. It is a commonly used component. So what is a magnetic ring inductor? What does it do? Today, I will explain to us. The role of magnetic ring ind
