Fixed Inductors

Fixed inductors, also known as chokes, are electro-magnetic components that are used to store energy in an electric field or magnetic field. These components are used to filter, deliver, couple, or store energy, and contain an inductor core that is made of wire coil and is often surrounded by additional material, such as ferrite core material. This is done to modify the current through the component and reduce or increase the magnetic field. People are commonly using fixed inductors for circuits that perform certain operations, so it is important to choose the right type of inductor.

This article focuses on the ISC1812BN221K fixed inductor, which is a current-compensated inductor used for a variety of applications. It is a winding type that has a specific inductance and rated current. The ISC1812BN221K is typically used for power supplies and can be used for applications that require a wide inductance adjustment range. This type of inductor is typically used for applications where the current can vary and the inductance needs to remain constant.

ISC1812BN221K Application Field

The ISC1812BN221K fixed inductor can be used for several different applications, including power supplies, DC-DC converters, multi-output converters, and voltage regulators. It can be used in circuits that require frequency modulation and pulse-width modulation control. The ISC1812BN221K can also be used for inrush current protection and other types of surge protection circuits. It is typically used in consumer products, industrial equipment, medical devices, and automotive and aircraft applications.

Working Principle

The ISC1812BN221K fixed inductor works by storing energy in an electric field or magnetic field. This occurs when a current is passed through the inductor’s coils, creating a magnetic field around the inductor. This magnetic field generates voltage that is proportional to the rate of change of the current. The inductor’s inductance is determined by the number of turns of the inductor’s coil, the permeability of the material in the core, and the physical dimensions of the inductor.

The ISC1812BN221K inductor features a unique design, made up of two coils placed in parallel. This arrangement is what allows the inductor to provide current compensation for the power supply. The inductance of the inductor is determined by the number of turns in each coil, the width of the gap between the two coils, and the core material that is placed between the two coils. This design allows the inductor to adjust its inductance as the current it is passing changes. In this way, it can compensate for changes in the current and keep the power supply stable.

The ISC1812BN221K fixed inductor can also be used in circuits where inductance is needed to be adjusted quickly. Using the dual coils, two different coils of differing turns can be switched in and out to create different inductances. By adjusting the number of turns on one of the coils, the inductance can be quickly adjusted to create the desired effect. This is especially useful when the circuit needs to respond quickly to changes in the environment or other conditions.

Conclusion

The ISC1812BN221K fixed inductor is an ideal component for a variety of applications where current compensation and inductance adjustment are needed. With the dual-coil design, the inductance can be quickly adjusted to provide the desired effect. This inductor is commonly used for power supplies, DC-DC converters, multi-output converters, voltage regulators, and other similar applications. Understanding the application field and working principles of this inductor can help electronics engineers in better designing power supply and frequency modulation circuits.
