Fixed inductors have become essential components of electronics circuits. From power supplies to signal amplifiers, they are critical elements found in many applications. The 4379R-683HS series of fixed inductors from Semitec are designed for high current applications up to 4A and feature permissible ripple currents up to 18A for very small volumes and high energy storage capabilities.

The inductor is constructed with nickel-plated steel and consists of a wire coil wound around a magnetic core. The inductor\'s size and arrangement of the coil determine these characteristics, including inductance value, current-handling capacity, and frequency range.

The highest current ratings of 4379R-683HS fixed inductors come from their high saturation magnetics. These inductors feature an air wound winding structure, unique winding distribution, low winding loss, and high power output. This provides excellent ripple current suppression while ensuring the product\'s operating temperature remains in the preferred range.

The 4379R-683HS inductors are used in a variety of applications like voltage regulation, high frequency switching mode power supplies, as well as battery chargers, and DC-DC converters. The inductors deliver superior EMI noise filtration, high energy storage, low profile, excellent performance, high reliability, low noise and low ESR. As a result, these inductors are well suited for electricity applications requiring high power and reliability.

The 4379R-683HS inductors work on the principle of magnetic fields. The coil inside the inductor creates a magnetic field when current passes through it. This magnetic field opposes changes in current flow and thus generates opposition to current changes which limits the rate of change of current. Thus, inductors help to reduce current spikes and voltage fluctuation, allowing for smoother and consistent power.

Semitec\'s 4379R-683HS series of inductors are ideal for providing clean, reliable power and are a top choice for high current, low noise applications. The design and construction of the inductors help provide energy storage at high frequencies and ensures reliable operation over time. The inductors also feature a compact design and are RoHS compliant. These features make the 4379R-683HS series of fixed inductors a leading choice for electronics design applications.
