Fixed Inductors

Inductors are characterized as components that store electric and magnetic energy in the form of a magnetic field. Fixed inductors are components with a fixed inductance, they take many physical shapes and sizes, and usually can dissipate very little power in comparison to variable inductors. While fixed inductors come in various shapes and sizes, they all have the same basic working principle of energy storage and release.

One type of fixed inductor is the 9250A-102-RC. This is an axial lead type inductor that produces a high current for a wide variety of applications. It has a cost-effective design and is small enough to be placed in tight spaces. The inductor is made from a ferrite core with aluminum wire windings to produce a high inductance rating and low impedance.

One major application of the 9250A-102-RC is in power supplies, for filtering and damping AC/DC signals. It is used to reduce noise and ripple and increase the efficiency of power use. It is also used in low-voltage DC/AC power distribution systems, where it can provide isolation from transient spikes and EMI noise. In audio amplifiers, it can be used to filter out static and add resonance to the signal.

The working principle of the 9250A-102-RC fixed inductor is based on Faraday\'s Law of Induction. Inside it, a magnetic field is created by the current flowing through the inductor. This field induces a reverse current in the circuit, creating what is known as the “back EMF”. This back EMF opposes the applied current, limiting the amount of current that can flow in the circuit. Thus, the inductor acts as a current filter, regulating the flow of current in the circuit.

In most power supply applications, the 9250A-102-RC works as a choke. A choke is a two-terminal electrical component that reduces voltage and current spikes and increases the input voltage. A choke works by slowing the rise time of a voltage waveform or the rate of current change, reducing noise and EMI interference. The 9250A-102-RC also works as a filter to prevent low-frequency signals from passing through the input source.

The 9250A-102-RC fixed inductor is an essential component in many electronic designs, used to store and release energy, regulate current flow, and improve signal integrity. It is an incredibly versatile and cost-effective device that can be used in many power supply, audio amplifier, and low-voltage DC/AC power distribution systems, as well as many other applications.
