Fixed inductors generally refer to electrical components which are made with coils of conductive wires and have terminals where the currents can enter or exit. Often referred to as chokes, inductors are used to impede the flow of current in the desired direction and allow it to flow freely in the other direction. The particular inductor we will be discussing is the PT750-2050-VM, an air core inductor made from copper and steel which is primarily used in power supply and RF circuit applications.

The PT750-2050-VM inductor is a general-purpose inductor with a value of 750uh@20ma, a saturation current of up to 20amps and an inductance tolerance of ±5%. It has a shielded core housing with a mounting height of 0.590 inches and a width of 0.385 inches. This product is housed in a UL94V-0 flame retardant black plastic case, with an operating temperature range of -40-85°C. The PT750-2050-VM is rated for 0-350Vdc. The PT750-2050-VM is a reliable choice for power supply choke applications, as it has low inductance variation over its operating temperature range and high ripple current capability. In addition, it has an improved thermal design for excellent heat dissipation.

The working principle of the PT750-2050-VM air core inductor involves using an electromagnet to induce a magnetic field around the coil whenever an electric current passes through it. The magnetic field created by the current will oppose any further increase of the electric current, thus restricting it, and the inductor will store energy in its magnetic field. The amount of opposition to the flow of current is referred to as inductance, which is measured in units of henries.

In the system of an electronic device, these inductors are used mostly in series with a capacitor, or in parallel with a resistor to filter the current. In power supply applications, they can be utilized in filter circuits to reduce the ripple and noise in the output waveform. In radio frequency (RF) circuit applications, they are used mainly to tune a circuit to a specific frequency, to suppress undesired frequencies, and increase circuit efficiency through impedance matching.

In conclusion, the PT750-2050-VM air core inductor is a reliable electronic component for use in power supply and RF circuit applications. Its working principle involves using an electromagnet to induce a magnetic field around the coil, which in turn restricts the current flow and stores energy in its magnetic field. As such, it can be used in filter circuits and in various radio frequency applications. The advantages of this inductor include its high ripple current capability, low inductance variation over its operating temperature range, and improved thermal design for effective heat dissipation.
