What is Inductor & Choke

Inductor is an element that can convert electric energy into magnetic energy and store it. The structure of the inductor is similar to that of a transformer, but there is only one winding. The inductor has a certain inductance, which only hinders the change of current. If the inductor is in the state of no current, it will try to prevent the current from flowing through it when the circuit is connected; If the inductor is in a state of current flow, it will try to keep the current constant when the circuit is disconnected. Inductor is also called choke, reactor and dynamic reactor.The original inductor was the iron core coil used by British M. Faraday to discover electromagnetic induction in 1831. In 1832, J. Henry of the United States published a paper on self induction. The unit of inductance is called Henry, or Heng for short. In the mid-19th century, inductors were used in telegraph, telephone and other devices. The inductors used by H.R. Hertz in Germany in 1887 and N. Tesla in America in 1890 are very famous, which are called Hertz coil and Tesla coil respectively.

Classification of Inductor & Choke

Self sensor

When a current passes through the coil, a magnetic field will be generated around the coil. When the current in the coil changes, the magnetic field around it also changes accordingly. The changed magnetic field can make the coil produce induced electromotive force (induced electromotive force) (electromotive force is used to represent the terminal voltage of the ideal power supply of the active element), which is self induction.

An electronic component, which is wound by a wire and has a certain number of turns and can produce a certain amount of self inductance or mutual inductance, is often called an inductive coil. In order to increase the inductance value, improve the quality factor and reduce the volume, iron core or magnetic core made of ferromagnetic material is often added. The basic parameters of inductor include inductance, quality factor, inherent capacitance, stability, passing current and service frequency. An inductor composed of a single coil is called a self inductor, and its self inductance is also called a self inductance coefficient.


When two inductance coils are close to each other, the magnetic field change of one inductance coil will affect the other inductance coil, which is mutual inductance. The size of mutual inductance depends on the degree of coupling between the self inductance of the inductance coil and the two inductance coils. The element made by using this principle is called mutual inductor.

Functional use of Inductor & Choke

Inductors mainly play the role of filtering, oscillation, delay and notch in the circuit, as well as screening signals, filtering noise, stabilizing current and suppressing electromagnetic wave interference. The most common function of inductance in circuit is to form LC filter circuit together with capacitance. The capacitance has the characteristics of “blocking DC and connecting AC”, while the inductance has the function of “connecting DC and blocking AC”. If the DC current with many interference signals is passed through the LC filter circuit, the AC interference signal will be consumed by the inductor into heat energy; When the relatively pure DC current passes through the inductor, the AC interference signal in it is also changed into magnetic induction and thermal energy. The higher frequency is most likely to be impedance by the inductor, which can suppress the higher frequency interference signal.

The inductor has the characteristics of preventing AC from passing through and allowing DC to pass smoothly. The higher the frequency, the greater the coil impedance. Therefore, the main function of the inductor is to isolate and filter the AC signal or form a resonant circuit with capacitors and resistors.

What does customer say about FBELE Company


Our company has just started to import Chinese products from this year and is not very familiar with customs declaration and transportation. FBELE has taken the trouble to help us handle the import, which has solved our worries at home. Very very very good service.


We choose FBELE as our partner because FBELE has its own plastic mold factory, which can help us customize products and provide prototypes, which provides a strong guarantee for us to design new products.
