Fixed Inductors offer an efficient and reliable way to store energy within an electrical system due to their ability to resist changes in current flow. They are inductively coupled components whose purpose is to limit the flow of current, thus allowing controlled voltage flow in an application. A widely used Fixed Inductor is the SDR0604-471KL.The SDR0604-471KL is a fixed inductor, or choke, consisting of four isolated windings, housed within an epoxy resin case. Its construction is unique from other similar products, as the inductor is formed by stacking multiple layers of thin foil. This allows for improved magnetic coupling and increased storage capacity.The SDR0604-471KL is typically used in high-frequency switching applications, including large power supplies, converters, lighting systems, TVs and computers. It operates in a temperature range of -40 to +85°C, and is available in an advanced anti-saturation design to provide greater voltage stability, perfect for high power density applications.When correctly implemented, the SDR0604-471KL operates at less than 1 ohm, providing a higher level of current control and ensuring secure power supply. Its power range capability extends from 3.6 to 6.6 Volt DC, with inductance values of between 3.6 to 44uH and current ratings as high as 17.4A.The SDR0604-471KL works on the principles of inductive coupling. As electrical current flows through the outer windings, an electromagnetic flux is created, which is then linked to the inner windings. This inner winding contains the resistance, resulting in a reduction of current flow. This process is known as inductive current limiting.The SDR0604-471KL is highly reliable and contains no moving parts, virtually eliminating mechanical noise and power loss. It also uses a solid-state design with four layers of insulation and provides tight environmental seals to ensure high humidity resistance.Overall, the SDR0604-471KL Fixed Inductor is an ideal solution for switching applications requiring high-current control and reliable power switching. It is also a cost-effective solution for applications that need to process and convert power from an AC to DC power supply, allowing smaller, lower-cost systems to be developed.The SDR0604-471KL’s ease of integration, efficiency of operation, and the simplicity of its mechanical and electrical design make it a popular solution for many applications. It is also highly reliable, incorporating no moving parts and offering a wide temperature range, making it an ideal choice for high-power applications.
