Fixed inductors are components with an inductance value that is fixed and not adjustable during its useful lifetime. The 3090-471F are a series of fixed inductor products from Susumu, designed for use in electronic based circuits. The purpose of this article is to provide a brief discussion of the application field and working principle of the 3090-471F products.

The 3090-471F products are designed for low-current applications, such as radio-frequency (RF) and voltage regulator circuits. They feature low-disturbance, low-noise design which makes them suitable for high-frequency applications. The inductors have a wide range of inductance and voltage values available to suit different applications. Additionally, they offer high inductance tolerance, minimal series resistance, and a 1% tolerance for operating temperature from –40°C to +125°C.

The 3090-471F products utilise a ferrite core material for the windings which provides a high resistance to self-heating and low core loss. A thin enameled copper wire is used for the windings to give superior mechanical strength and current carrying capabilities. The winding pattern of the inductors is designed to ensure maximum performance in the high-frequency range.

The working principle behind the 3090-471F products is based on Faraday’s law of induction. This law states that when magnetic flux passes through a conductor, an electric current is induced. In an inductor, the magnetic flux is produced from the current passing through it. This current creates a magnetic field around the inductor, creating a set amount of inductance that is determined by its design.

The main advantage of the 3090-471F products compared to other fixed inductor products is that they are able to offer a high inductance tolerance and a wide range of inductance and voltage values to suit different applications. Additionally, their low-disturbance, low-noise design makes them suitable for high-frequency applications.

In conclusion, the Susumu 3090-471F fixed inductor products are designed for low-current applications and are suitable for use in radio-frequency and voltage regulator circuits. They utilise a ferrite core material and thin enameled copper wire for the windings which provide high resistance to self-heating and low core loss. The working principle behind the inductors is based on Faraday’s law of induction. The main advantage of these products compared to other fixed inductor products is the high inductance tolerance, and the wide range of inductance and voltage values available.
