Fixed Inductors

An inductor is a type of electrical component which uses the principle of Faraday\'s Law of Electromagnetic Induction to generate a magnetic field when electric current passes through it. Fixed inductors are required in a variety of applications and vary by type and construction. One example of a type of fixed inductor is the 4470R-01G which has an air core and a nominal inductance of 10microhenries (µH).

Application field of 4470R-01G

The 4470R-01G fixed inductor is used mainly in battery chargers, portable electronic devices, audio equipment, stage equipment and LED lighting equipment. It can also be used in other applications including signal filtering, current sensing, switching regulators and switching conversion circuits.

Working Principle of 4470R-01G

The 4470R-01G is a two-terminal, basic air-core inductor with a nominal inductance value of 10microhenries (µH). It is designed to work within a temperature range of -40°C to +125°C. The inductor is constructed of a wire coil, an insulator sleeve and a ferromagnetic core. The coil consists of insulated wires which are wrapped around a ferromagnetic core. This creates a magnetic field when an electric current is passed through the inductor.

The 4470R-01G works on the principle of Faraday\'s Law of Electromagnetic Induction, which states that the induced EMF in a coil is proportional to the rate of change of the magnetic flux. In other words, when current passes through the inductor, a change in the magnetic field is produced, which induces an EMF. This EMF is opposed to the applied current and thus the inductor resists the flow of current, thereby creating an inductive reactance which is proportional to the frequency of the applied current.

The application of the 4470R-01G is mainly in high-frequency applications. In these applications, it serves to provide a stable voltage that does not fluctuate with changes in the load current. This stability of the inductor can also be utilized in oscillator circuits, where the inductor provides an inductance path for tuned-frequency oscillations.
