Fixed Inductors

Fixed inductors are components that store energy in a magnetic field when electric current passes through a conductor. They are used in a wide range of electronic applications like filters, power supplies and oscillators. The PT750R-1700 is an example of a fixed inductor that is used in a variety of applications.

PT750R-1700 Application Field

The PT750R-1700 is a small size, snap-on style, variable inductor which is ideal for signal filtering and signal conditioning. It is versatile enough to be used in a wide range of radio, audio, and video applications. The PT750R-1700 can also be used to create circuits with high power audio amplification.

The PT750R-1700 is suitable to use in the input stages of radio receivers because of its low profile and low noise characteristics. This inductor can also be used in the output stages of oscillators for temperature stability and high selectivity. It is also excellent for coupling amplifiers, signal generators, and power supplies.

The PT750R-1700 also works well with digital switched capacitor filters due to its low profile and low parasitic capacitance. It can be used to construct the filter circuits needed to reduce distortion and interference in digital audio applications. It also works well with LCD driver ICs and stepper motor circuits.

Working Principle

The PT750R-1700 is an adjustable inductor which works on the principle of a double ferrite core. When a current is passed through the winding, its flux is concentrated in the core area of the coil. This results in a higher inductance than when compared to a single core counterpart.

The inductance of the winding is adjusted by varying the number of windings around the core. As the number of windings is increased, the inductance increases. This is important because inductance is an important parameter in the design of inductor based circuits.

The core is usually composed of a ferrite material, which has an excellent permeability, hence providing a much higher inductance than that of an iron core. The use of ferrite also reduces the core loss, resulting in an inductor with high performance and stable operation.

Once the core is constructed, it is wound with wire, forming a coil. The size of the coil is then adjusted by alternating the number of turns of the wire. This in turn affects the inductance of the coil. The frequency response of the PT750R-1700 is also affected by changing the number of turns.

Once the power is applied to the inductor, the current is alternated. The magnetic field created by the current produces a force that opposes the current. This forces the magnetic field to lag behind the current, creating an inductive reactance in the circuit.

The PT750R-1700 is an example of a fixed inductor which is used in a variety of applications. With its low profile and low noise characteristics, it is perfect for use in radio, audio, and video applications. By varying the number of windings around the core, the inductance of the winding can be adjusted to create the desired circuit design.
