Fixed Inductors

A fixed inductor, such as the AIRD-02-122K, is an electronic component used to store energy in an electric field. Fixed inductors are commonly used in power supplies, dc-to-dc converters, filtering, and voltage regulation. They are also used to induce coupling between two circuits, suppress high-frequency transients, reduce high-frequency noise, and provide impedance matching.

What is a Fixed Inductor?

A fixed inductor is an electronic component with two electrical terminals. It normally consists of a coil of insulated wire wrapped around a magnetic core, such as ferrite or iron-powder, which is used to store energy in the form of a magnetic field. This field can be used to induce a current in nearby components or circuits.

How Does a Fixed Inductor Work?

When a voltage is applied to the terminals of a fixed inductor, a current flows through the coil. This current produces a magnetic field in the core, which stores energy and increases the inductance of the component. As the current increases or decreases, so does the magnetic field, and thus the inductance.In most cases, the inductance remains constant as the frequency of the input signal increases. This makes fixed inductors ideal for filtering high-frequency signals. They can also be used as part of an impedance-matching network to match the output impedance of one circuit to the input impedance of another, allowing signals to travel with minimal losses.

Types of Fixed Inductors

Fixed inductors come in various shapes and sizes and are classified by their inductance rating. The AIRD-02-122K, for example, is rated at 12.2uH – meaning that it will allow 12.2uH of current to flow through when a 1Amp is applied. Other common configurations include axial, radial, power, and foil inductors.

Common Applications of Fixed Inductors

Fixed inductors are used in a variety of applications, including power supplies, dc-to-dc converters, filtering, and voltage regulation. They are also used as a noise suppressor, helping to reduce high-frequency transients and interference. Additionally, they can be used in impedance matching, where the output impedance of one circuit is matched to the input impedance of another.

Advantages and Disadvantages of Fixed Inductors

Fixed inductors offer a number of advantages over other types of components, including their low cost, high inductance, and good frequency stability. They are also small and lightweight, making them ideally suited for compact electronic designs. On the downside, fixed inductors are prone to saturation if too much current is applied, which can cause them to burn out.

Conclusion

Fixed inductors, such as the AIRD-02-122K, are electronic components with two electrical terminals. They are typically used to store energy in an electric field and are commonly employed in power supplies, dc-to-dc converters, and voltage regulation. Fixed inductors can also provide impedance matching and suppress high-frequency transients. While they offer numerous advantages, such as their low cost and small size, they can also be susceptible to saturation if too much current is applied.
