Fixed inductors are electrical components used in electrical circuits for filtering, tuning, and electrical protection devices. A fixed inductor, like the SD20-3R3-R, is a heat-resistant, extremely reliable component for use in arduous environments. The SD20-3R3-R offers a range of performance characteristics, such as voltage shock and vibration resistance, which make it suitable for a variety of applications.

The SD20-3R3-R has a wide range of applications in RF applications. Its extremely low temperature coefficient and high Q features make it an ideal choice for use in commercial, professional, and industrial applications such as cellular phones, broadcast antennas, satellite receivers, satellite communications, and satellite navigation systems. It is also commonly used in switched-mode power supplies, motor control circuits, inverters, electronic ballasts, and many other high-reliability applications.

The working principle of the SD20-3R3-R is fairly simple. It consists of a ceramic core encased in a metal shell, with high-current conductors on either side. When an AC signal passes through the inductor, the core creates a magnetic field that induces a current, which produces a high-frequency alternating voltage. This alternating voltage is then converted to a DC voltage, typically by the use of a rectifier. The changing magnetic field in the core also affects the electrical resistance of the inductor, creating an impedance that can be used to filter or tune the frequency of the signal.

The performance of the inductor depends on its construction and components. For instance, the current rating of the inductor is directly related to the number of turns in the winding, as well as the size of the core material. The inductance is also dependent on the core material and the number of turns in the winding. A larger number of turns increases the inductance, while a higher-resistance core material decreases it. This flexibility allows users to customize the inductance of an inductor to suit specific applications.

The SD20-3R3-R is a durable and reliable fixed inductor, providing great performance in a wide variety of applications. Its high-current and low temperature coefficient features make it an ideal choice for RF and high-reliability industrial applications. Its simple construction and adjustable inductance values make it a versatile component, suitable for a variety of purposes.
