Fixed inductors, also known as coils, are electrical components that are made up of a source of current, which is then wound around a ferromagnetic core. The PM518S-330-RC is a type of fixed inductor, which typically finds application in high frequency power management, allowing for optimised power conditioning when employed in an AC-DC converter or DC-DC converter circuit.

This model of inductor utilises a ferrite-core magnet such as a spool, ‘E’ core, iron powder, or other such material, and is constructed with a winded copper wire. Its features include a rated inductance of 0.18µH, a resistance of 3.3mΩ, and an operating temperature range of -55°C to +105°C. The PM518S-330-RC has also has a maximum DC current of 1.8A and, when compared to the standard range of products available, can demonstrate significantly lower losses at high frequencies.

The working principle of this particular fixed inductor is based on the idea that when an electric current flows through a wire winding placed around a ferrite-core, it produces a magnetic field around the core of the wire. This magnetic field produces a counter-electromagnetic field due to the magnetomotive force, and these two fields interact with each other to produce an electric current, allowing for the necessary power.

One of the primary uses of fixed inductors such as the PM518S-330-RC is for high power conversion of alternating and direct currents in switched-mode power supplies (SMPS). These power supplies are needed when power is required to be converted from one form to another, most commonly from AC to DC or DC to AC. SMPS can also be used to increase or decrease a voltage or to draw current from a given source with as little energy loss as possible and are commonly found in laptops, computers, and many other electronic devices.

As previously discussed, the PM518S-330-RC offers a range of features, including high frequency performance at low losses, making it particularly suitable for use in SMPS. Additionally, its high-temperature performance and its low winding resistance provides consumers with reliable, economical operation and improved power conversion efficiency. Furthermore, because of its form, size, and compatibility with electronic components, the PM518S-330-RC remains popular for its convenience and durability.

Fixed inductors such as the PM518S-330-RC have a variety of applications in industrial, responsible for regulating the flow of power from a high-current power source to a low-voltage consuming component. For example, it can be used to regulate the electric motor of industrial machinery or devices, powering light circuits, providing release valves for pressure relief, and even forming the basis for electric heating systems. Furthermore, it is often used in construction, allowing for automated control systems for an entire building.

The PM518S-330-RC is a small package fixed inductor, and its many features include excellent high-frequency performance, high temperature performance, low winding resistance, and low energy costs. With its compact size and convenience, it can be a great addition to many applications. Ultimately, the PM518S-330-RC fixed inductor remains a popular and reliable choice for those looking to optimise power conversion and reduce energy loss.
