Fixed inductors are components that carry a variety of functions in a variety of electronic or electrical circuits. They play an important role in the current electronics industry. Among them, the SP1812-102K application field and working principle are worth studying for engineers.

SP1812-102K Overview

The SP1812-102K is an REFEW fixed inductor that combines high-level performance with a high saturation current together with a small size. These inductors are packaged with a tape and reel or bulk lead-frame form factor, and have low losses, magnetic shield casings with airtight seals, and between 1μH and 22μHof inductance. Compared to manually wound coils, the SP1812-102K fixed inductor supports more temperature variation and includes a wider range of products.

SP1812-102K Applications

Since fixed inductors can be adopted to many electronic or electrical circuits, the applications of the SP1812-102K are quite wide too. It is an ideal component for the line filtering applications such as the Adaptive Power Filter and Neuronics, which is used in the network communications field. In addition, it can also be used in other areas such as the automotive electronics area, telecommunication, server and storage, consumer electronics and home appliance industry and so on.

SP1812-102K Working Principle

Fixed inductors are basically copper coils wrapped around iron cores. The SP1812-102K fixed inductor also works on the same principle. The winding around the core is composed of a copper wire whose length, volume ratio and cross-sectional area perfectly match the inductance. When the current enters the winding, an induced electromotive force will be generated, thus producing an oppositely directed self-induced electromotive force, which combats the current flowing in the winding, forming a predetermined inductance for the entire inductor. The larger the current, the greater the amount of counter electromotive force resulting in greater inductance.

Conclusion

In conclusion, SP1812-102K is a REFEW fixed inductor. It has many advantages such as a high saturation current, low loss, and magnetic shields with airtight seals. Wide frequency range, temperature variation support, and rich product range make this component perfect for line filtering applications such as Adaptive Power Filter and Neuronics, because they can meet the requirements for signal processing. The working principle of the SP1812-102K is simple, the larger the current, the greater the amount of counter electromotive force resulting in greater inductance. And the component can also be used in other areas such as automotive electronics, telecommunication, consumer electronics, and home appliance industry, making it a powerful electronic component.
