Fixed InductorsInductors are basic components in any electronic circuit, and are used to store energy in a magnetic field and to transfer electrical energy into a different form. Fixed inductors are the simplest type of inductor, and they are used to provide a controlled reactance in a circuit. There are a wide variety of fixed inductors, each with its own unique characteristics and applications.One type of fixed inductor is the SD7030-820-R. This is a fixed power inductor that combines high inductance and high current capacity. It is a radial leaded device with a low profile and low profile height, making it relatively easy to mount. It is also coated with a heat resistant coating to increase its durability and reliability.The SD7030-820-R is designed to be used in DC and AC power circuits, power conversion, filter circuits, and other applications that require increased inductance and current capacity. The inductance value is 8.2mH, and the current capacity is 7A. This makes it well suited for a variety of applications, including high current switching, current recirculation, line frequency chokes, slow turn-off control, and high power circuits.The working principle of the SD7030-820-R is based on basic principles of electromagnetism. The inductor consists of a coil of wire wrapped around a magnetic core. When a current passes through the coil, a magnetic field is created around the coil. This magnetic field interacts with the core, which in turn creates a voltage and current in the opposite direction of the one flowing in the coil. This phenomenon is called back-EMF, and it enables the inductor to store energy in the form of a magnetic field.The amount of energy stored by the SD7030-820-R is proportional to its inductance value. This means that the higher the inductance, the more energy it can store. The inductance also determines the reactance of the device, which is a measure of its resistance to alternating current (AC). The higher the reactance, the more effective the inductor is at blocking or slowing the flow of AC current.The SD7030-820-R is well suited for a wide range of applications, including power control, switch mode power supplies, motor and generator control, power conditioning, pulse power applications, high frequency operation, and power line conditioning. Its combination of high inductance and high current capacity makes it a valuable component in many different types of circuits. Due to its low profile and low profile height, it is relatively easy to mount and it is also protected by a heat-resistant coating to increase its durability and reliability.
