Fixed Inductors

Fixed Inductors are an essential part of many electrical circuits. They are used to create inductance in a given circuit, thus providing efficient current flow and desired voltage levels. The LHL08NB821K is a type of fixed inductor that is widely used in many electronic applications, due to its design features.

Features

The LHL08NB821K is a fixed inductor that features a high-power, Ferrite core with copper windings. It has a total inductance of 8uH and a current rating of 0.45A. The device has a temperature range of -40°C to +85°C and features an impedance of 9.7 ohms.

Application Fields

The LHL08NB821K was designed for use in various electronic applications, such as power supplies, digital and analogue circuits, telecommunications, and automotive electrical systems. Additionally, the device can be used in a wide range of noise suppression and sideband filtering applications. Its winding style and inductance make it ideal for use in small-signal and power transformer circuits.

Working Principle

The working principle of the LHL08NB821K is based on the application of the principles of a transformer. This type of inductor uses two or more windings that are wound on the same core, with the current flowing through one of the windings creating a magnetic flux. This flux then induces a voltage in the other winding, thus creating inductance in the circuit.

When a current flows through the primary winding of the inductor, a magnetic field is formed. The magnetic field is conducted through the core material, which induces a voltage into the secondary winding. As the current run through the secondary winding, a magnetic field is created that opposes the magnetic field in the primary winding. This creates a ‘back EMF’, reducing the flow of current as the current tries to increase. This reduction of the current is known as inductive reactance.

The development of the ‘back EMF’ reduces the current passing through the circuit, thus allowing the desired voltage levels to be achieved. It also improves efficiency as the current is regulated and controlled.

Conclusion

The LHL08NB821K is a type of fixed inductor that features a Ferrite core with copper windings. It has a total inductance of 8uH and a current rating of 0.45A, making it ideal for many electronic applications. The working principle is based on the application of the principles of a transformer, creating a ‘back EMF’ when current passes through the primary winding. This ‘back EMF’ reduces the flow of current in the circuit, allowing for efficient current flow and desired voltage levels.
