Fixed inductors are electronic components that store energy in a magnetic field when electrical current is applied to them. Specifically, a PM105S-471M fixed inductor is a reliable, low-cost inductor for use in DC/DC converters, uninterruptible power supplies (UPSs), motor controls, audio electronics and other switching power technologies where small size and low cost is paramount to success.

In operation, a fixed inductor produces a magnetic field in its core when a current is passed through its winding. The magnetic field relatively intensifies as the current increases and, after reaching a certain level, causes the inductor to saturate. Part of the field stored in the inductor core is directed back into the winding, thereby forming a self-resonant circuit. This resonance creates a “back-EMF” that opposes the applied input voltage, which limits the amount of current allowed to pass through the inductor. The amount of current limited by the inductor is determined by its inductance value.

The PM105S-471M fixed inductor is ideal for use in a wide variety of AC and DC switching power supply applications. Its small size makes it perfect for circuit board applications, while its low cost makes it an attractive option for those looking to keep their budget low without sacrificing performance. Additionally, this inductor features a high degree of repeatability, thanks to its reliable construction that includes bonded ferrite cores and insulated copper windings.

The building blocks of the PM105S-471M fixed inductor are a metal core and an insulated, copper wire winding. The core is made of a ferrite material that provides a relatively low reluctance path for the magnetic flux. The windings are carefully wound on the cylindrical core and covered with a specially formulated insulation sleeve. This sleeve is non-conductive and protects the windings from any possible shorting or damage. The tightly wound windings help ensure that the inductor’s inductance remains stable with a high degree of repeatability across a wide range of temperatures and loading conditions.

While the purpose of the PM105S-471M fixed inductor is to provide a stable energy source in circuits, its construction and operation offer numerous other benefits. For instance, its high current carrying capacity allows it to handle high voltages and increase the efficiency of power supplies. Its compact size makes it an ideal choice for applications where space is limited, and its low weight and cost add to its appeal.

The PM105S-471M fixed inductor is a reliable, low-cost device that can be used in a wide variety of switching power supply applications. Its high inductance and current carrying capacity make it suitable for a range of AC and DC power supply systems, and its compact size and low weight make it perfect for circuit board-based designs. The insulated copper windings ensure that the inductance remains stable in varying loading conditions, and the ferrite cores help boost its current carrying capacity. All these features combine to make the PM105S-471M fixed inductor an ideal choice for commercial and industrial applications.
