Inductors are coils made of enameled wire or yarn covered wire, also called high-frequency chokes or choke coils.

The types of inductors include fixed inductors and adjustable magnetic core inductors. Fixed inductors are divided into air core inductors, iron core inductors and ferrite core inductors.

The inductance of an inductor is related to the number of turns, wire diameter, tightness, material, and material.

The unit of inductance is Henry.

Characteristics of inductors: Faraday's law and Lenz's law.

Faraday's law: The inductance coil will generate alternating current when cutting the magnetic field lines. When current flows through the inductor, a magnetic field is formed around it.

Lenz's law: When an instantaneous current flows through the inductor, the inductor will hinder the current.

The applications of inductors include DC constant current filtering, special obstruction to alternating current (passing low frequency and high frequency), generators, motors, electromagnets, relays, contactors, solenoid valves, induction cookers, reverse Transformers, argon arc welding machines, cutting machines, electric batons and scalpels, etc.



Shenzhen Lingyu Micro Technology Co., Ltd. The company was established in May 2007, and Lingrui Technology (Hong Kong) Co., Ltd. was established in the same year. The company is positioned as a component distributor serving the electronics manufacturing industry. The main business is divided into two parts: active components (signal amplifier PA, crystal oscillator, RF Devices, etc.) and passive components (capacitor MLCC, inductor MLCI, chip beads, resistor Chip Resistors) two parts, respectively obtained DARFON (Dafang Electronics), ASJ (ASJ resistance), and CEC (China Electric Panda), SAMSUNG (Samsung), FH (Fenghua), WALSIN (Huaxin Technology), UNIOHM (Hou Sheng), VT (Xianke), SUNLORD ( Sunlord), GGEC (Guoguang), YAGEO (National Giant), Foshan Blue Arrow and other famous brands in the Mainland China and Hong Kong are authorized agents. Since its establishment, the company has received strong support from original component manufacturers and a wide range of customer manufacturers. Its performance has continued to grow, and its business scope has gradually expanded. At present, it has formed a solid platform supported by various component manufacturers; with communication products, network products, and consumer products. Electronic products, security monitoring, GPS, power products, automotive electronics and other industries are customer groups focusing on customers; the business radiation area centered on the Pearl River Delta region, the company will continue to actively cooperate with customer needs with the best service and quality to achieve common win.
