Fixed Inductors

Fixed inductors are a type of passive electronic component used in a variety of electrical and electronics applications. They are widely used in the power conditioning and power supply systems of computers, laptops, and other digital equipment. Common types of fixed inductors include air core, ferrite core, and pot core inductors. The 0819R-02K fixed inductor is a specially designed component used in high frequency switching applications.

Application Field

The 0819R-02K fixed inductor is commonly used in high frequency switching circuits. Its small form factor and low profile make it ideal for use in circuits for computers, laptops, mobile phones, tablets, and other digital equipment. In addition to its use in power conditioning and power supply systems, it can also be used in communications and control systems, RF circuits, audio systems, and more.

Working Principle

At its core, a fixed inductor is an electronic component that stores energy in the form of a magnetic field. This process is accomplished by circulating electrical current around the core material through the inductor’s windings. The core material used in the 0819R-02K fixed inductor is a high-frequency ferrite material, which allows it to handle high frequencies with low loss. The windings are enclosed in a small form factor package to reduce inductance and improve high frequency performance. When a voltage is applied to the inductor, the current flowing through it generates a magnetic field that is proportional to the current, as per the formula B = μ*l*i (where μ is the magnetic constant, l is the length of the inductor, and i is the current through the inductor). This magnetic field interacts with the core material to produce a back-emf voltage that opposes the applied voltage. This opposition to the applied voltage causes the current to be limited; the inductor’s impedance thus reflected in the impedance of the circuit.

Conclusion

The 0819R-02K fixed inductor is a high-frequency component designed for use in high frequency switching circuits. It is small and low profile, making it ideal for use in digital electronics and other applications where space is limited. It features a high-frequency ferrite core material and low loss windings, allowing it to provide efficient energy storage in the form of a magnetic field. The inductor’s opposition to the voltage produced by applied current further improves its high frequency performance.
