Fixed inductors are a type of electrical component that stores energy in an electric current. They consist of a wire loop wound around a core, typically made of copper, and are used to create high-frequency alternating electric fields. The SP1812-822K is a type of fixed inductor made by Smalls Electronics. It is designed for use in a variety of industries, including aerospace, automotive, and consumer electronics.

The SP1812-822K is optimized for use in switch and regulator applications that require high-frequency performance. It is designed to provide low-loss performance even in high-voltage, high-current scenarios. This makes it ideal for applications such as motor drivers and power supplies, which require long-term stability and low distortion. The SP1812-822K also features a wide temperature range, making it suitable for use in extreme temperature environments.

The SP1812-822K is a shielded, low-profile component. It offers up to 1.37 mH of inductance and can handle up to 1.9 AT power. Its peak current rating is up to 9.35 A and its maximum DC resistance is 0.082 Ohms. The unit measures 8.2 mm in length and 8.2 mm in diameter, and has a weight of 8 g.

The working principle of the SP1812-822K can be described as follows: when an alternating current (AC) passes through the inductor, it produces an electromagnetic field in a clockwise direction. This field is opposed by a field in an anti-clockwise direction created in the inductor by the same AC current. In this way, energy from the AC current is stored in the inductor, which is then released as the field collapses. This energy can then be used to power other components.

Overall, the SP1812-822K is a reliable and efficient fixed inductor with applications in a variety of industries. Its low profile, high current-handling capability, and wide temperature range make it ideal for many industrial applications. Its working principle is simple but effective, enabling it to efficiently store and release energy from an alternating current.
