Chip inductors can be divided into low-power inductors and high-power inductors. Chip inductors, low-power inductors are mainly used in frequency selective circuits and oscillating circuits; high-power inductors are mainly used in dc/dc converters, used as energy storage components or lc filtering. There are three types of low-power inductors: wire-wound, multilayer, and high-frequency; high-power inductors are all wire-wound.
Preventive testing is an important link in the operation and maintenance of power equipment, and it is one of the effective programs to ensure the safe operation of power equipment.
A mark (mark) that can distinguish the directionality is often attached to the wire-wound inductor. If the structure of high-power inductors is not completely symmetrical, high-current chip inductor manufacturers will produce characteristic differences in the packaging direction. Therefore, in order to make the product give full play to its due characteristics during use, the product is often marked with a mark to indicate its directionality.
In many electronic application scenarios, people will use step-up transformers, but you may not know the working principle of step-up transformers, so it is very troublesome to choose.
Amorphous strips are mainly used to replace transformer core materials (silicon steel, ferrite), and belong to a new generation of transformer cores. Transformers can be divided into frequency power frequency (50hz or 60hz), intermediate frequency (60hz to 20khz), high frequency (above 20khz) according to frequency.
In many electronic application scenarios, people will use various types of transformers, whether it is a high-frequency transformer or a low-frequency transformer, the manufacturing process is similar. Next, Zou Gong, a senior design engineer from Shenzhen Yingzhe Technology Co., Ltd., will introduce the general production process of transformers.
In recent years, high-sensitivity pressure sensors with flexibility, biocompatibility and stretchability have attracted widespread attention in the fields of wearable electronic devices and smart skins.
The high frequency transformer is the most important part of the switching power supply. The switching power supply generally uses a half-bridge power conversion circuit. When working, two switching transistors are turned on in turn to generate a 100kHz high-frequency pulse wave, and then the high-frequency transformer is used to step down and output low-voltage alternating current.
Knowledge of Transformer and Inductor
Transformers and inductors are easily confused because they have the same physical shape. There is only one rule that can be distinguished between them, the transformer is marked with "QTK", and the inductor is marked with "QHP".
