Fixed Inductors

Fixed inductors, also known as coils, chokes, or reactors, are passive electrical components which are used for signal routing, filtering, and regulation in a wide variety of different electronic systems. The SD18-820-R is a fixed inductor that is widely used in the telecom and instrumentation industry. It has two lead wires and is constructed from high quality materials to ensure maximum performance, durability, and reliability in any circuit configuration.

SD18-820-R Application Field and Working Principle

The SD18-820-R is a fixed inductor that is commonly used in telecom and instrumentation systems. It has a core made up of ferrite material, which is wrapped with enameled copper wire to form the coil. The SD18-820-R is capable of withstanding temperatures of up to 275°C (527°F). Its rated current range is 0.3 to 1.3 A and its rated voltage range is 130 to 400 VAC.The fixed inductor works by storing electrical energy in a magnetic field, thereby reducing the amount of current flowing through the circuit. As the current passes through the inductor, it produces a magnetic field, which then causes the inductor to act as a filter, blocking certain frequencies while allowing others to pass. The inductor also helps regulate the current so that it won’t overload the circuit, as well as providing noise reduction.The applications of the SD18-820-R fixed inductor vary widely and include signal routing, filtering, power conversion, signal conditioning, and voltage regulation. It is particularly useful in telecom and instrumentation systems which require precise control of current and voltage. The SD18-820-R is also ideal for applications requiring EMI/RFI suppression, as it helps reduce electrical noise which can interfere with electronic circuitry.The advantages of using a fixed inductor over other components include higher efficiency, increased reliability, better heat dissipation, and more uniform performance. Additionally, the SD18-820-R is affordable and easy to install, making it an ideal choice for budget-conscious projects.In conclusion, the SD18-820-R is a reliable and efficient fixed inductor that is suitable for a wide range of applications. It is capable of withstanding high temperatures and is well suited for systems which require precise current and voltage control. Its affordability and ease of installation make it a popular choice for many electronics projects.
