Fixed Inductors

Fixed inductors are the basic component of electronic circuits. They are used to provide a constant level current to a circuit, reducing the amount of energy required to power the device. Inductors are used in a wide variety of applications, such as battery chargers, power supplies, and other electronic equipment. The S1812-123G fixed inductor is a popular choice, providing high levels of performance in a compact form factor.

S1812-123G Application Field

The S1812-123G fixed inductor is designed to be used in a wide variety of applications. Generally, it is used in signal and power converter circuits, voltage and current converters, power supplies, transformers, and other related circuits. This inductor is also suitable for use in DC-DC converters, DC-AC inverters, switched mode power supplies, AC-AC power converters, power filters, and clock oscillators.

S1812-123G Working Principle

The core of the S1812-123G is made from a ferrite core material, which is composed of two layers of material encased in copper wire. This configuration forms a magnetic circuit, which is the basis of how the inductor works. When an electric current is applied to the inductor, a magnetic field is created and stored around the core. This acts like a battery, storing the energy when the current is removed. When the current is reapplied, the stored energy is released back into the circuit, providing a continuous flow of current.The current flow through the inductor is determined by the inductor\'s inductance, which is measured in mH (Milli-Henries). The higher the mH of the inductor, the more current it can provide. Generally, the S1812-123G Inductor has an inductance of 2.4 - 3.6 mH.

Conclusion

The S1812-123G fixed inductor is a high-quality inductor, designed for use in a wide range of electronic circuits. It is made from a ferrite core material, and provides a constant level current when an electric current is applied to it. The current flow is determined by the inductance of the inductor, which ranges from 2.4 to 3.6mH. As a result, it is ideal for use in signal and power converter circuits, voltage and current converters, power supplies, transformers, and other related circuits.
