Fixed Inductors are components that help generate and store energy in electric and electronic circuits. They are usually found in power supplies, filters, amplifiers, oscillators, and other circuits. The LAL04TB4R7K is a common type of fixed inductor used in various electronic applications. This article will discuss the application field and working principle of the LAL04TB4R7K.

The LAL04TB4R7K is a fixed inductor, which consists of an air-core, ferrite-core, or ferrite-bead-core, with two winding coils around it. The two coils are connected in series and the inductor is usually soldered onto a circuit board. The LAL04TB4R7K has a nominal inductance of 4.7µH and can handle a current of up to 0.7A. It also has a saturation current of 0.5A.

The main applications of the LAL04TB4R7K are in AC/DC converters, voltage regulators, motor drivers, and other power supplies. It is also used in various electronic filters, such as low-pass, high-pass, band-pass, and band-stop filters. The LAL04TB4R7K is commonly used in power supplies and other applications where a stable current is necessary.

The working principle of the LAL04TB4R7K is based on the law of electromagnetic induction. The two coils act like a transformer. When a current is passed through one of the coils, an electromagnetic field is generated, which induces a voltage in the other coil. This voltage is then applied to the circuit, creating a stable current.

The LAL04TB4R7K is capable of storing and delivering energy. When a steady current is applied, the inductor stores the energy and continuously releases it while the current is maintained. When the current is interrupted, the stored energy is released as a voltage spike. This allows the inductor to act as a regulator in AC/DC converters and voltage regulators.

The LAL04TB4R7K is a useful component for applications needing a stable, regulated current. It can be used in a variety of power supplies, filters, and other circuits. Its high saturation current and low inductance make it suitable for high-frequency and high-power applications. Its ability to store energy and release it as regulated voltage makes it suitable for AC/DC converters and other voltage regulation circuits.
