Fixed inductors refer to a type of electronic component that works by inductance changes. Depending on their classification, they can be used in different applications, including resistance, capacitance, and inductance. One particular example of a fixed inductor is the SD12-4R7-R. This device has a wide range of potential applications in the field of electrical engineering.

The SD12-4R7-R is a surface-mount inductor designed to store and deliver energy for multiple applications. It has a core made of ferrite material coated in a sheet steel to provide excellent core stability. The device features a 18 MHz resonance frequency with a high self-resonance impedance, making it well-suited for signal processing, RF measurement, impedance matching, and anti-interference filter circuits.

The working principle of a fixed inductor is relatively straightforward. When an AC current passes through the inductor, a voltage is induced by a magnetic field. The higher the level of the current, the higher the voltage generated. Additionally, the voltage induced is inversely proportional to the size of the inductor.

The SD12-4R7-R can also be used in electronic circuits to control power. For example, large inductors are used to counteract power surges or limit voltage spikes in sensitive circuits. They can also be used to store energy for later use, such as in electric vehicles.

The SD12-4R7-R is a useful device for applications requiring high-precision inductance control. Its 18 MHz resonance frequency ensures reliable operation and its ferrite core offers excellent stability. With its wide range of applications, the SD12-4R7-R is a handy tool for engineers looking for efficient inductance control.
