Fixed Inductors

Fixed Inductors are electrical passive components that are used to provide a controlled amount of inductance to an electrical circuit. They are widely used primarily for filtering and noise reduction, and are also used in power conversion and switching circuits. They are also often referred to as "chokes" or "inductor coils".

One type of fixed inductor that is commonly used in electronic circuits is the NLCV25T-220K-PFD. This device consists of a cylindrical ferrite core with two concentric windings of enamel-coated copper wire. The windings are separated by an insulating medium.

The NLCV25T-220K-PFD is designed for applications where moderate-to-high inductance and a low DC resistance are required. It has a very low-level DC resistance (<1Ω) and can provide up to 220 mH (millihenry) of inductance. This device is often used in electrical circuits for filtering, noise reduction, and power conversion applications.

The working principle of fixed inductors is based on the physical phenomenon known as inductance. Inductance is basically the opposition to the flow of alternating current (AC) in a circuit. It is produced by components of the circuit, such as coils and other conductors, as well as by the magnetic flux in a circuit. As alternating current flows through a circuit, an electric field is created around the components, which opposes the flow. This electric field generates a magnetic field, which then inducts opposing voltage and current in the circuit components, thus producing the effect of inductance.

Inductors can be used in various ways in a circuit, mainly to filter signals, reduce noise, and transform voltage levels. By passing alternating current through an inductor, it can be used to filter out unwanted signals, such as those from radio frequency (RF) interference, or low-frequency noise. Additionally, inductors can also be used to convert DC voltage levels, by storing the current in their coils as magnetic energy, and then releasing it as AC voltage.

The NLCV25T-220K-PFD fixed inductor is an ideal device for applications requiring an inductor with a low resistance and moderate-to-high inductance. Its wide range of uses makes it a popular choice for engineers and technicians working on electronic circuits. The combination of its low DC resistance and high inductance makes it ideal for filtering, noise reduction, and power conversion applications.
