Fixed inductors, commonly referred to as coils, are essential electrical components that store and transfer energy. The NRS4018T3R3MDGJV is a low-frequency inductor developed for space-saving applications. This inductor features a combination of a small size and high inductance, enabling improved energy efficiency in a compact form factor.

The NRS4018T3R3MDGJV is constructed with a traditional drilled ferrite core and wound copper wire. This inductor has a rather low DC resistance in the 0.6-1.2 ohm range, and can provide inductance values from 22 to 33 microhenries. This inductor is a high-performance choice for applications calling for low ESR and moderate energy storage in a small form factor.

The NRS4018T3R3MDGJV is well-suited for power supply isolating circuits, smoothing circuits, filter coils, and serial resonance circuits. When used in power supply applications, the NRS4018T3R3MDGJ increases conversion efficiency and reduces power loss. In filter circuits, it allows for better signal ripple attenuation and greater frequency stability. In resonance circuits, its relatively low DC resistance ensures that stored energy can be utilized with minimal losses.

The working principle of the NRS4018T3R3MDGJV is based on the relationship between current and magnetic flux, known as Faraday’s Law. When a shifting magnetic flux passes through a set of coils, the changing flux causes an electromotive force, and therefore a current, to be induced. This is known as electromagnetic induction. In the NRS4018T3R3MDGJV, an alternating current passed through the inductor generates a varying magnetic flux that passes through the surrounding ferrite core. The changing flux then induces a current within the coil, allowing energy to be either stored or transferred, depending on the application.

The NRS4018T3R3MDGJV is an ideal choice for applications requiring a small form factor and good inductance performance. Its combination of a small size and high inductance make it an excellent choice for achieving improved energy efficiency in a limited space. The fact that it can provide both storage and transfer of energy makes it a versatile component for a wide range of applications, from power supply circuits to filter and resonance circuits.
