Principle of common mode inductor
Common mode inductance filter circuit, La and Lb are common mode inductance coils. In this way, when the normal current in the circuit passes through the common mode inductance, the reverse magnetic fields generated by the currents in the inductance coils wound in the same phase cancel each other...Read more -
What is the wireless charging coil?
What is the wireless charging coil? Simply tell, the wireless charging receiver coil is to receive the current emitted by the wireless charging transmitter coil. When the transmitter coil emits current, the receiver coil receives the emitted current to the current storage terminal. The characteri...Read more -
How to detect the inductance coil?
When we select and determine the use of inductance coils, the first thing we think of is the quality of inductance coils and whether they are tested according to standards. Therefore, inductance coils must be strictly tested when they are used. In fact, the whole process is very simple. The edito...Read more -
What is inductor?
The magnetic loop inductor is an electronic component. Its main function is the conversion of electromagnetic induction. An electrical wire is the simplest inductance. It is used as an antenna to convert electrical energy into electromagnetic waves. The air-core coil is a little more complicated ...Read more -
Two packaging methods for chip inductors
SMD inductors, belongs to a structural form of inductance, which mainly play the role of choking, decoupling, filtering, coordination, and delay in the circuit. Chip inductors have prolonged the life of many consumer electronic products and improved the abnormal quality of products, and the perfo...Read more -
One-piece inductors, the development of one-piece inductors
With the development of the electronics industry, electronic products have begun to show the development trend of “four modernizations”, namely miniaturization, integration, multi-function, and high-power. In order to comply with the popularization of electronic products, the electron...Read more -
The difference between one-piece inductors and ordinary inductors
With the development of science and technology, equipment in many fields has been manufactured. In order to maintain a stable balance of current circuits in terms of power, the electronics industry needs inductance products that are small in size, high in power, low in cost, and suitable for inte...Read more -
How to solve the problem of abnormal noise caused by the chip inductance
If the chip inductor has abnormal noise during the operation of the equipment, what is the reason? How to solve it? What is the analysis made by the editor of Xinchenyang Electronics below? During operation, due to the magnetostriction of the chip inductor, it will emit abnormal noise through the...Read more -
Answers to questions about the shelf life of chip inductors and influencing factors
Almost everyone in the industry knows the shelf life of chip inductors, usually about 1 year, but this is not absolute. It depends on the production process and storage environment of the inductor, and the chips produced with inferior materials and placed in a humid environment The life of the in...Read more -
Common mode inductance acts on the input end of the power module
A common mode inductor means that two coils are wound on the same iron core, with opposite windings, the number of turns and the same phase. Commonly used in switching power supplies to filter common-mode electromagnetic interference signals, EMI filters are used to suppress electromagnetic waves...Read more -
Analysis of factors that need to be paid attention to when selecting chip inductors
When we are choosing a product, we usually choose according to external factors. The same is true for chip inductors. We need to consider some external or internal factors to choose a suitable chip inductor for us, which affects the chip. There are many factors for inductance If the product needs...Read more -
How to distinguish shielded inductor and unshielded inductor?
I believe many people are confused about the comparison of shielded inductor and unshielded inductor. According to the difference of magnetic shielding performance, there are two different names of shielded inductor and unshielded inductor. Shielded inductor includes chip inductor and I-shaped in...Read more
