Fixed inductors are known as “passive electronic components” — components that allow energy, such as current or voltage, to pass with minimal attenuation or blocking. Fixed inductors can be in the form of coils, wire circuits, and ferrite cores, and the most commonly used type of inductor is the air-cored inductor. Air-cored inductors are versatile and have a variety of use cases, but what is the application field and working principle of 103R-103FS inductors?

103R-103FS inductors, also known as “1.4 mH 1 Amp Fixed Inductors,” are a type of fixed inductor that are used to filter out radio-frequency noise. They are designed to be used in the DC-DC converter supply and the output filters of high-efficiency switching power supplies. They can also be used in wide frequency range oscillator circuits, resonant circuits, and other high current noise-reduction devices. The 103R-103FS inductors are made with a multi-layer ferrite core for low inductive resistance, a flow-through type winding for flexibility and sturdiness, and a flame-retardant enclosure for safety.

The working principle of 103R-103FS inductors is based on Faraday’s law of induction, which states that a changing magnetic field will induce a voltage in a loop of conductor. An inductor consists of a coil of wire, and when a current is passed through it, it produces a magnetic field. This magnetic field opposes any change in the current, and as a result, the inductor acts as a low-pass filter, allowing low-frequency signals to pass through while blocking out high-frequency signals. The resistance of the 103R-103FS inductors is low, which allows the current to flow through easily, but the inductance is very high, which helps filter out high-frequency noise.

103R-103FS inductors belong to a set of specific inductors that are designed to reduce radio-frequency noise in electronics applications. They are made with a ferrite core for low inductive resistance and a flame-retardant enclosure for safety, and they are often used in DC-DC converters and power supplies. The working principle of 103R-103FS inductors is based on Faraday’s law of induction, which states that a changing magnetic field will induce a voltage in a loop of conductor. As a result, the inductor acts as a low-pass filter, allowing low-frequency signals to pass through while blocking out high-frequency signals.
