Fixed inductors are electrical components that help control the amount and direction of electric current in an electrical circuit. They are used in a variety of different applications, from power supply units to surge protectors and more. One type of fixed inductor is the S1812R-122J. This inductor is a non-polarized, medium power inductor that offers a high reliability and durability. In this article, we will discuss the application fields and working principle of the S1812R-122J.

The S1812R-122J is a fixed inductor that is typically used in power supply units, DC-DC converters, switching regulators, SMPS and various other electronic products. These inductors are designed with high-temperature, composite pure aluminum cores and are fully shielded for optimal performance. They provide high inductance values ranging from 1.2uH to 470uH, with a rated voltage up to 200V and a rated current up to 7.5A. This makes them well-suited for a wide range of applications.

The S1812R-122J is designed to control or modulate the flow of electric current. This induction process is accomplished by passing an electric current through a copper coil. When the current passes through the copper coil, it induces a magnetic field which sets up a voltage, also known as an EMF (electromotive force). This EMF opposes the flow of current producing a back emf. The magnitude of the back emf is proportional to the rate of change of current. This makes it possible to control the direction and magnitude of the current. In other words, the S1812R-122J works by controlling the amount of electric current in an electrical circuit.

The S1812R-122J also offers great reliability and durability. The inductor is carefully designed to prevent overheating or short circuits. It is able to endure demanding environments and operating conditions. Additionally, because of its shielded design, the S1812R-122J is able to reduce interference from neighboring components. This makes it ideal for use in high-frequency and high-density circuits, as well as in applications that require a large amount of current.

In conclusion, the S1812R-122J is a versatile fixed inductor that is ideal for a wide range of applications. It offers great reliability and durability, and is capable of controlling the direction and magnitude of electric current in an electrical circuit. With its shielded design, it is able to reduce interference from neighboring components and operate in demanding environments. Therefore, it is an excellent choice for use in power supplies, DC-DC converters, switching regulators, SMPS and many other electronic products.
