Fixed Inductors

An inductor is an electronic component, usually made of a coil of wire, which stores energy in a magnetic field generated by the coil itself when current passes through it. Fixed inductors, also known as “fixed-value” inductors, are common devices used in electronic circuits to provide a constant and controlled electrical current. They are designed to have a specific inductance when carrying a given current.The SD18-3R3-R is a fixed inductor widely used in power electronics, radio communication, and automotive systems. It is a surface-mount device that has an operating temperature range of up to 125 °C and can withstand transient voltages up to twice its operating voltage. The SD18-3R3-R is a high-performance part designed for use in all types of power electronics circuits, such as multilayer inductors and pulse transformers. Specifically, it is designed for operation in high-speed switching circuits that require low EMI and high transient voltage protection.The SD18-3R3-R inductor features a high-reliability solder joint that is resistant to vibration and shock. It is also UL-recognized for its reliable performance. The inductance values range from 1.2µH to 33µH with currents up to 8A. The SD18-3R3-R offers several advantages as compared to standard power inductors. It can provide up to 30% inductance increases over standard inductors due to its extra layers of wiring. It also has a low EMI output, making it suitable for use in power electronics systems. When it comes to operation, the SD18-3R3-R is easy to install and can be mounted with either screwholes or solder. It has a low self-resonant frequency and a wide saturation range, which makes it ideal for use in power electronics designs. The SD18-3R3-R also offers good heat dissipation characteristics due to its two-piece construction and die-cast cover. The inductor is constructed with dual-layer magnetic wires that help reduce eddy current losses. This allows the inductor to handle high current demands while still providing good thermal performance. To sum it up, the SD18-3R3-R is a high-performance fixed inductor designed for use in all types of power electronics applications. It is easy to install, has a wide saturation range, low EMI output, and excellent thermal performance. It is UL-recognized and has a high-reliability solder joint for reliable operation.
