Fixed inductors are electronic components that use a winding of wire around a core to create a magnetic field. The NRS4018T470MDGJV is an example of a type of fixed inductor. It is a high-current, low-resistance inductor designed for use in high-frequency switching power supplies.

The NRS4018T470MDGJV is a surface-mount, low-profile component that has a much higher current carrying capacity than other inductors in its size range. It has a winding made of multi-strand wire that is wound around a ferrite core. The wire is insulated and the core is potted with epoxy to protect and stabilize it. The epoxy also serves to dampen vibration and reduce electrical noise.

The NRS4018T470MDGJV inductor is designed for use in high-frequency switching power supplies. It is ideal for applications requiring high current with low losses. It has a high saturation current rating and can handle currents up to 23 Amp. It also has a low DC resistance of 0.5 mOhm. This low resistance creates higher efficiency and lower power dissipation, resulting in more efficient power supplies.

The working principle of fixed inductors can be explained by Faraday’s law of induction. This law states that a changing magnetic field around a conductor induces an electric current within the conductor. When current is applied to the inductor’s windings, the changing magnetic field induces an electric current inside the windings. This current in turn creates a changing magnetic field that further induces more current within the inductor.

The magnetic field created inside the inductor depends on the inductance and the current applied to the inductor. The inductance is determined by the physical properties of the inductor, including the number of turns in the winding, the diameter of the core, and the cross-sectional area of the wires used to make the winding. The greater the inductance of the inductor, the greater the magnetic field that will be created for the same current.

The NRS4018T470MDGJV fixed inductor is one example of a high-current, low-resistance inductor that is ideal for use in high-frequency switching power supplies. Its winding is wound around a ferrite core and potted with epoxy for stability and noise reduction. Its high saturation current rating and low DC resistance make it highly efficient, while its physical properties give it a high inductance value. All these features come together to make the NRS4018T470MDGJV a great choice for high-frequency switching power supplies.
