Fixed inductors are used in many industries and electronic circuits. The S1812R-105H is one of these established models. This article will discuss the application field and working principle of the S1812R-105H.

An inductor is a device that stores energy through the use of a magnetic field. The S1812R-105H is a fixed inductor, meaning it stores a fixed amount of energy. This type of inductor is commonly used in power supplies, radio circuits, and other electronic circuits and equipment.

The S1812R-105H is an axial-leaded, surface mount, low-profile, shielded, ceramic-core inductor with a nominal inductance of 10.5µH. It is also capable of handling frequencies up to 5V peak-to-peak and resisting temperatures of up to 1,485C or beyond. The S1812R-105H contains an internal metal shield that prevents electromagnetically induced interference (EMI) from affecting the coil. Additionally, its internal lead frame ensures an accurate inductance throughout its environmental temperature range.

The working principle of the S1812R-105H is relatively simple. When a current passes through the inductor, it creates a magnetic field that induces an EMF in the inductor. This EMF is proportional to the rate of change of current in the circuit, and is given by the equation EMF=-L\frac{dI}{dt}. The EMF acts as a opposition force to the current, causing the current to reduce. This is known as inductance, and is the primary feature of all inductors.

The S1812R-105H is a valuable component and has many applications. These include filters, impedance matching components, radio receivers, and signal conditioners. In addition, the S1812R-105H is an important component in switching power supplies, as it serves to limit and control voltage and current spikes. It can also be used to create LC oscillating circuits, which are used to generate electrical signals. The use of this inductor makes it an invaluable part of any electronic circuit.

In conclusion, the S1812R-105H is a fixed inductor that stores a fixed amount of energy. Its primary feature is inductance, which is the opposition force that the inductor creates when current is passed through it. This component has many applications, including filters, impedance matching components, radio receivers, signal conditioners, and power supplies. It also has an internal metal shield to ward off any EMI interference. Overall, the S1812R-105H is a reliable and versatile component that is used in many electronic circuits and should not be overlooked.
