Fixed Inductors

Fixed inductors are devices that store energy in the form of an electrical field. They are commonly used in circuits where other passive components like resistors and capacitors cannot provide sufficient energy storage. The SDR0503-560KL is an example of a fixed inductor with a wide application field.Inductors are categorized by their electrical characteristics, including inductance, resistance, and capacitance. They are also classified by their physical form, such as through-hole, surface mount, or magnetized. The SDR0503-560KL is a surface-mount inductor with a rated inductance of 560 mH. It is designed for use in AC/DC power supplies, motor drive circuits, and high temperature applications.The SDR0503-560KL consists of a ceramic core wrapped with wire. Its physical characteristics make it suitable for applications requiring high levels of performance and reliability. The inductor is also designed to withstand high temperatures, up to 125° C.The SDR0503-560KL has a low DC resistance (0.12 ohms) and a typical DC resistance (0.19 ohms) at 100kHz. This allows it to provide higher levels of current compared to resistors in the same size and temperature range. It also has an operating temperature range of -25° C to +125° C.On the other hand, its analysis of the magnetic properties reveals that the SDR0503-560KL has a low amount of core loss (0.021 W/GHz). This allows the inductor to operate at much higher frequencies with minimal performance loss.To better understand how the SDR0503-560KL works, it is important to understand its working principle. The inductor works by storing energy in the form of a magnetic field due to the flow of current through the windings of wire. This stored energy then creates a magnetic field which induces a voltage when the current is changed.For example, when current is increased the magnetic field expands and a voltage is induced in the opposite direction of the current flow. This voltage opposes the change in current, therefore reducing the current in the circuit. When the current returns to its original value, the induced voltage is no longer present and the circuit can begin the process again. This inductive action creates a damping effect on the current flow which can be used to limit the rise or the fall of the current.In conclusion, the SDR0503-560KL is an example of a fixed inductor with a wide range of applications. It is designed for use in AC/DC power supplies, motor drive circuits, and high temperature applications. The inductor is made of a ceramic core wrapped with wire and is able to withstand up to 125° C. Its magnetic properties are ideal for high-frequency and temperature-resistant applications. Its inductive action works by creating a damping effect on the current flow which can be used to limit the rise or the fall of the current.
