Fixed inductors are passive devices used to store or dissipate energy in electric circuits. The SD3812-820-R is a fixed inductor which is widely used in various applications. Its main features include its high performance, reliability and robustness, small size, and a wide variety of form factors to meet the needs of different application scenarios.

The SD3812-820-R is a fixed inductor with a compact size of 8 mm x 8 mm by 10 mm (0.3” x 0.3” x 0.4”). It is a very reliable component that can provide a high insulation resistance and very low leakage current. It is also designed with a very low DC resistance, meaning that it can handle power levels much higher than most other inductors in its class.

The SD3812-820-R can be used in a wide range of applications, including power supplies, motor control, telecommunication, audio, imaging, and more. It is particularly suitable for applications that require high efficiency, such as PWM (pulse width modulation) or switching regulator circuits. As it is designed with low DCR and low leakage current, it can also be used in high frequency applications, such as ferrite transformers.

When it comes to the SD3812-820-R\'s working principle, it is based on the Faraday’s law of induction, which states that when current passes through a wire coil, a magnetic field is created and the magnitude of the field is proportional to the amount of current flowing through the coil. This magnetic field then induces a voltage across the coil, which is also proportional to the amount of current. This effect is called self-inductance and is used in the SD3812-820-R fixed inductor to store or dissipate energy in electric circuits.

In conclusion, the SD3812-820-R is a fixed inductor used in a wide variety of applications. Its small size, high performance, reliability and robustness make it ideal for high efficiency switching regulator circuits. In addition, its working principle, which is based on Faraday\'s law of induction, is used to store or dissipate energy in electric circuits.
