Fixed inductors are essential components in many electronic circuits and are used to store energy as electric current in a magnetic field. They have various applications including filtering, voltage regulation, tuned circuits, and more. One example of a fixed inductor is the ATFC-0402-8N2B-T. This particular inductor has a 4.2nH value and a saturation current rating of 1.14A. The inductor is available in a 0402 surface-mount package, which makes it suitable for applications where board space is limited.

The most common application of these inductors is in power supply circuits. They can be used to filter out noise and spikes, as well as regulating the output voltage. Fixed inductors are also used in radio frequency (RF) circuits, where they are commonly employed as part of a tuned circuit. In this application, the inductor functions to form part of the circuit’s resonance frequency, allowing the circuit to selectively receive or transmit a signal at a specific frequency.

Fixed inductors can also be used as part of a boosting circuit. This type of circuit is used to increase the output voltage of a power source. The inductor is placed in parallel with the power source and it stores energy in its magnetic field. When the load is placed across the inductor, it dumps its stored energy into the load, thus boosting the voltage.

The working principle of fixed inductors is based on Faraday’s law of induction. According to this law, when a current flows through a wire, it creates a magnetic field that surrounds the wire. This magnetic field then induces an electromotive force (EMF) in any nearby wires. When a current is applied to the inductor in the form of a changing voltage, a changing magnetic field is created. This in turn induces an EMF in the wire that opposes the applied voltage, thus hindering the flow of current. This opposition to the change in current is known as inductance, and it is this property that is used to store energy in the inductor’s magnetic field.

The ATFC-0402-8N2B-T inductor is a versatile component that can be used in a variety of applications. It is suitable for use in power supply circuits and tuned circuits, as well as boosting circuits. In all of these applications, it works on the principle of Faraday’s law of induction, allowing it to store energy in its magnetic field.
