Fixed Inductors
4445R-12K application field and working principle
A fixed inductor is an inductor of which the inductance value is fixed and does not vary. This type of inductor is used in various electronic circuits due to its notable properties.
Working Principle
The working principle of a fixed inductor is relatively simple. An AC voltage is passed through a coil of wire, and as a result of the inductance of the component, an electromagnetic field is generated. The generated field induces a current in the coil of wire in a direction which opposes its own motion. This opposing current, termed the “back current”, reduces the original voltage across the coil. The degree of reduction is determined by the inductance of the component, and this is what is referred to as the “inductance value”.
Application Field
The 4445R-12K is a fixed inductor, and as such it is used in a number of electronic circuits. Typically, it is used to suppress high frequency noise, or as a low-pass filter. It can also be used to decouple digital and analog circuits, or as a basic electrical component in a variety of circuits. As an industrial resource, the 4445R-12K is often used in a wide range of applications including regulated power supplies, cellular base station circuits, and medical imaging equipment. It is also often employed in consumer electronics devices such as telephones, satellite television, and gaming consoles.
Advantage
There are a number of advantages to using fixed inductors such as the 4445R-12K. Foremost, the inductance value of the component can be easily varied by varying the number of turns in the inductor coil. This allows for various applications to be satisfied, such as the decoupling of digital and analog circuits. Furthermore, since the inductance is constant, they are not affected by changes in temperature or frequency, allowing them to be used in a variety of applications. Additionally, they require minimal power to operate.
