Inductor
Inductor classification: 1. Classification by structure: Air core inductor: No magnetic core, only wound by wire. Suitable for high-frequency applications. Iron core inductor: Use ferromagnetic materials as magnetic core, such as ferrite, iron powder, etc. This type of inductor is usually used i...Read more -
What is an inductor?
1. What is an inductor： An inductor is an electronic component that stores magnetic field energy. It is wound with one or more turns of wire, usually in the form of a coil. When current passes through the inductor, it generates a magnetic field, thereby storing energy. The main characteristic of...Read more -
The principle of inductor storing electrical energy
The core function of inductance is to store alternating current (storing electric energy in the form of a magnetic field), but it cannot store direct current (direct current can pass through the inductor coil without hindrance). The core function of capacitance is to store direct current (storing...Read more -
LED light not working but has power repair tips
In modern life, we are increasingly using LED lights as primary lighting. They are energy efficient, long-lasting, and environmentally friendly, and are widely used in homes and commercial places. However, what should we do when LED lights no longer shine? Don't worry! T...Read more -
How to detect the core of a high frequency transformer?
How to detect the core of a high-frequency transformer? People who buy the core of a high-frequency transformer are afraid of buying a core made of low-grade materials. So how should the core be detected? This requires understanding some detection methods for the core of...Read more -
Curie temperature of transformer core
“Some time back, someone asked if the magnetic core has a temperature resistance grade. And someone replied like this: ‘Temperature resistance grade is for insulating materials. The magnetic core isn’t considered an insulating material, so it doesn’t have a specific temper...Read more -
Detailed explanation of transformer high voltage failure caused by skeleton
High-frequency transformers are one of the key electronic components for electronic products. If an abnormality occurs during use, the electronic products will explode, and in severe cases, it will threaten human life. According to the test specifications of high-frequency transformers, withstand...Read more -
Characteristics of cores of different shapes
Common core shapes include can, RM, E, E-type, PQ, EP, ring, etc. Different core shapes have different characteristics: 1. Can The skeleton and winding are almost completely wrapped by the core, so the EMI shielding effect is very good; the can design makes it more expensive than the cor...Read more -
What is no-load/load operation of high-frequency transformer?
Among the basic concepts of high-frequency transformers, there is a working state of high-frequency transformers called no-load operation of transformers. No-load operation of high-frequency transformers means that the primary winding of the transformer is connected to the power supply and the s...Read more -
Will high-power inductor transformers become a future development trend?
With the development of the new energy market, inductor transformers are gradually developing towards high frequency, high voltage and high power. Will high-power inductor transformers become a future development trend and realize large-scale automated production? According to the national dual c...Read more -
How LEDs Were Invented？
The invention of LEDs (light emitting diodes) was a multi-stage process involving contributions from many scientists. Here are some key historical moments in the invention of LEDs: Early theory and experiments: 1907: British scientist H.J. Round first observed that the semiconductor mate...Read more -
Why LED can emit light？
Light-emitting diode is a special diode. Like ordinary diodes, light-emitting diodes are composed of semiconductor chips. These semiconductor materials are pre-implanted or doped to produce p and n structures. Like other diodes, the current in the light-emitting diode can easily flow from the p p...Read more
