Inductors are electronic components that store energy in the form of an electromagnetic field. Fixed Inductors are used to control current flow, reduce interference, and provide electrical isolation in circuits. The SRP4030FA-1R0M products from Sumida are typical examples of fixed inductors. It is a non-polarized, molded power inductor suited for a wide range of application in power supply and electronic equipment.

The SRP4030FA-1R0M is available in an 8mm solid type and features a metal external and internal ferrite core comprised of a high-grade MnZn ferrite material. It has a special, copper coated terminal construction. The SRP4030FA-1R0M offers a wide operating temperature range of -40°C to +125°C, allowing for use in harsh environments.

Typical specifications of the SRP4030FA-1R0M fixed inductor include inductance of 1.0 mH-10µH, inductive tolerance of ±30%, current range of 0.5A-6A, and a DC resistance (DCR) range of 0.14mΩ-37.5mΩ. The SRP4030FA-1R0M has a height of 8.0mm, an external diameter of 7.8mm, and a resonance frequency of 0.24MHz. Its mounting surface, after mounting soldering, is flat and smooth, allowing high stand-off capacitance between the component and the mounting surface.

As an example application, the SRP4030FA-1R0M can be used in switched-mode power supplies as filters for AC or DC input. The SRP4030FA-1R0M can also be used in automotive applications like navigation and audio systems, as well as electronic office equipment such as photocopiers and printers.

The working principle of the SRP4030FA-1R0M fixed inductor is based on Faraday\'s law of induction, which states that when a conductor is placed in a changing magnetic field, an induced electric voltage is created. This is due to the exchange of energy between the magnetic field and the electric current in the conductor. In the SRP4030FA-1R0M, two coils of wire are arranged so that they are exposed to the same magnetic field. This produces a stronger magnetic field that can be used to induce voltage into a circuit.

The SRP4030FA-1R0M fixed inductor is a versatile component that can be used in a variety of applications. Its wide operating temperature range and special external and internal ferrite core construction make it well suited for power supply and automotive applications. The SRP4030FA-1R0M is a powerful tool in the design toolbox for engineers, offering robust performance in a wide range of environments.
