Fixed InductorsInductors, or coils, are electrical components that are designed to create magnetic fields. The fixed inductors are components that are built into the circuit and used to store energy. Specifically, the SD3112-820-R is a surface mount Fixed Inductor which is typically used in power circuits like power supplies and line noise filters.The SD3112-820-R is made with an inductance rating of 820nH to induct high currents but minimal losses. Due to its low profile, it can fit into most of the applications without taking up too much space, while the terminals are copper-plated for improved thermal energy conduction. Finally, this device is perfect for high temperature environments that can reach temperatures as high as 155°C.The SD3112-820-R is used in a variety of applications, such as motor drives, power circuits, line noise filters, and signal conditioning. This device is particularly useful for power-sensitive circuits, since it stores energy in the form of a magnetic field. This allows the inductor to provide the necessary energy over and over again without additional sources, such as batteries or capacitors.In a circuit, the SD3112-820-R acts as an energy storage device, using the induced current of the coil to store energy. It is also used to limit current and provide a constant energy output for the circuit.When an AC signal is applied to the device, the current passes through the coil and creates a magnetic field within the coil. This magnetic field is proportional to the applied current, and interacts with the electric field within the circuit. As the magnetic field increases, so does the inductance of the device, which causes the current to slow down. This slowing of the current is the induced current.As the induced current decreases, the energy stored in the magnetic field is converted to mechanical energy. This mechanical energy moves in the form of an electric charge, which can be used to provide a continuous, constant energy supply in the circuit.The SD3112-820-R\'s fixed inductor design has been optimized to be used in power or signal conditioning applications. It is a perfect choice for high temperature environments and circuits that require power efficiency. The copper terminals also provide improved thermal energy conduction, ensuring that the device is able to dissipate the heat of the electric fields.
