Fixed inductors are an indispensable part of electronic circuits, mainly used for energy storage and frequency adjustment. The SP1812R-822K product belongs to this type, and has the characteristics of low profile, high reliability, ultra-small size, long life and wide temperature range. This article explains the application fields and working principles of the SP1812R-822K.

SP1812R-822K is mainly used in precision circuit applications such as metering, measurement, control, broadcasting and computers. It is suitable for extreme temperature environments such as high temperature and low temperature ranges. It has the characteristics of low noise, high frequency stability, and high insulation. Moreover, due to its ultra-small size, it can save more space and reduce the overall size of the circuit.

The working principle of SP1812R-822K is relatively simple. When connected to a power source, it will draw electric current. This current flows through the inductor, generating an electromagnetic field around it. The electromagnetic field generates an opposing force, known as inductance. This force opposes the increase of current and creates an opposing voltage in the circuit. This voltage, known as the counter electromotive force, is the basic working principle of an inductor.

SP1812R-822K inductors are commonly used in circuit design because of their low profile, good stability and low cost. In addition, their operating temperature range is -40℃~105℃, their resistance to temperature changes is high, and they can be used in various electronic products and appliances. Besides, these inductors also feature high insulation between coil-core and core-shield, which helps them resist high voltage and strong RF interference.

In summary, SP1812R-822K belongs to the category of fixed inductors, and is mainly used in precision circuits. It features low profile, high reliability, ultra-small size, long life and wide temperature range. The working principle of SP1812R-822K is based on the electric current flowing through the inductor generating an electromagnetic field, which generates an opposing voltage known as inductance to oppose the increase of current. The characteristics of this product also include good stability, high insulation, low noise, and high frequency stability.
