Fixed inductors are electronic components that store energy in a magnetic field. A fixed inductor such as the S4924-392H is usually used in switching power supplies, motor drives, radio frequency (RF) circuits, filters, transformers, and voltage regulators. These applications require an induction current with low resistance and excellent stability over time, making the S4924-392H ideal.

The S4924-392H fixed inductor is a cylindrical component consisting of a coil of insulated copper wire wound around a core material. The core material is made of metal with a high magnetic permeability such as permalloy, which directs and enhances the magnetic field through the coil winding. The wire is enamel-coated copper, which resists oxidation and provides a more reliable connection. The S4924-392H also includes a terminal or lug for making connections.

The key characteristics of the S4924-392H fixed inductor include nominal inductance, saturation current, and DC resistance. For example, the S4924-392H has a nominal inductance of 392 H (H = henry, the SI unit of inductance), a saturation current of 2.8 A, and a DC resistance of 0.07 Ohm.

The working principle of a fixed inductor is based on Faraday’s Law of Induction. When current flows through the coil of the fixed inductor, it generates a magnetic field that induces an electromotive force (EMF) in the coil. This EMF opposes the flow of current, thus creating a resistance. When the amount of current flowing increases, the EMF increases as well, resulting in a higher level of resistance. This helps to regulate the flow of current and can be used to achieve low ripple and high efficiency in power supplies.

The S4924-392H fixed inductor is widely used in numerous electronics applications such as power supplies, motor drives, RF circuits, filters, transformers, and voltage regulators. It is designed for use in a range of power levels, from low (up to 1.5A) to high (up to 2.8A). The fixed inductor is rated up to 500VAC and has a temperature range of -40 to +85C. It is constructed with a UL-approved thermoplastic casing for protection against the elements.

In conclusion, the S4924-392H fixed inductor is a reliable and effective component for applications requiring inductance and stability. It is designed to operate in a wide variety of environments, and its key parameters, including nominal inductance, saturation current, and DC resistance, make it an ideal choice for switching power supplies, motor drives, RF circuits, filters, transformers, and voltage regulators.
