Fixed Inductors: 3090-392F Application Field and Working Principle

In today’s surge of technical developments, electrical devices play an increasingly important role in our lives. A fixed inductor is one of the most common components used in electrical engineering applications. The specific model 3090-392F is a type of surface-mount chip inductor, and today we will consider its application field and working principle. Fixed inductors are basically coils of wire that provide inductance and can be used for several purposes such as signal modulation, AC/DC power conversion, and signal transmission. They are also widely used in power supplies, filters, converters, transformers, and many other electrical devices. The 3090-392F is a general purpose chip inductor, which is primarily used as an inductor in a DC/DC converter application. It can also be employed in power distribution and signal filtering, as well as providing impedance matching and noise isolation. The 3090-392F is an axial-leaded inductor that features a compact size and excellent electrical performance. It has a resonance frequency of 300MHz, an inductance of 3.90uH, and a self-resonance at 500MHz, making it suitable for high-power and high-frequency applications. The product is made with a ferrite core, and it is RoHS compliant and lead-free. It also has a good heat dissipation capability, which ensures that it can operate in a wide temperature range. When it comes to the working principle of a 3090-392F fixed inductor, it is very simple. The inductor is basically made up of a coil of wire, which is wound around either a ferrite or iron core. When an AC current is passed through the inductor, it creates a magnetic field, which generates an opposing electric current. This is known as a back electromotive force, and it helps to limit the amount of current that can pass through the circuit. Thus, the inductor acts as a filter to regulate the current, and protect the circuit from excessive voltage. In conclusion, the 3090-392F is a versatile fixed inductor that has a wide range of applications in electronic engineering. Its small size and excellent electrical performance make it ideal for high-power and high-frequency applications, and it is also RoHS compliant and lead-free. Furthermore, its simple working principle that relies on the creation of an opposing electric current helps it to protect circuits from overvoltage.
