Fixed inductors are key components in electrical circuits and play an important role in electric power, electronics, renewable energy, sensing, and more. The S1812-104K is a common fixed inductor that is used in many applications. This article will provide a comprehensive overview of its application field and working principle.

The S1812-104K is a fixed inductor that is made from a ferrite core and is wound with copper wire. The inductor is available in four different sizes ranging from 0.44uH to 3.3uH and ratings up to 3.3A. This wide range of sizes and ratings makes it well-suited for a variety of applications such as high-power switching, power management, telecom, automotive, medical, industrial, and more.

The primary application field of the S1812-104K is in switching power supplies. When combined with a switching transistor, it is able to provide a steady output voltage by modifying the frequency of the switching pulse. When used in DC-DC converters, the inductor slows down the rate of voltage change and helps maintain the stability of the voltage. It is also used in low-noise DC-to-DC converters as it has low core losses and a high-magnetic flux density.

The S1812-104K is also suitable for use in DC-AC inverters. The inductor helps maintain the output voltage at a steady level while providing high efficiency. The copper wires used in the inductor provide good thermal conductivity, allowing it to withstand high temperatures. This makes it suitable for use in various industrial applications.

The working principle of the S1812-104K is fairly simple. The inductor is made of a ferrite core that is wound with copper wire. A current passes through the wire, which creates a magnetic field around the core. This magnetic field induces an electromotive force (EMF), which opposes the current flow. As a result, it changes the magnitude and direction of the current, making it beneficial for use in switching power supplies.

In addition to switching power supplies, the S1812-104K is also used in voltage regulators and in impedance matching systems. In the voltage regulator application, the inductor helps maintain the voltage by filtering out high frequency noise. In the impedance matching application, the inductor helps maintain the desired impedance of the circuit for optimal frequency response.

The S1812-104K has many uses in a variety of applications. It is used in switching power supplies, voltage regulators, inverters, and impedance matching systems. It is made of a ferrite core with copper wire winding and is available in various sizes and ratings. Its primary working principle is based on the magnetic field created by the current flowing through the wire, which induces an EMF that opposes the current flow. This makes it a highly efficient and reliable fixed inductor for many applications.
