1840-28K

Fixed inductors are electrical components that store energy in a magnetic field. They are found in many electrical and electronic circuits, and their basic design and working principle can be traced back to the 1800s. The most common fixed inductors are the 18407L and 28K types, and their application and working principles will be discussed in more detail below.

1840-28K Application Field

The 1840-28K is a inductor that is primarily used in power regulation and switching circuits. It is often used in a wide range of voltage-controlled resistors, oscillator circuits, phase-locked loops (PLLs), rectifiers, light-emitting diodes (LEDs), field-effect transistors (FETs), and other circuits that require regulation and switching. It can also be used in analog and digital signal filtering, medical imaging, and other high-tech applications.

1840-28K Working Principle

The working principle of the 1840-28K is based on its core material, which is usually ferrite. This material can be magnetized due to its magnetic flux permeability and can retain a certain amount of energy in its magnetic field. When a current is passed through the inductor, the ferrite core will act as a magnet and store energy in its magnetic field. When an external current or voltage is applied to the inductor’s winding, the magnetic field created by the core will induce a voltage in the winding of the inductor.

This induced voltage will cause the current to flow in the direction of the external current or voltage, and the resistance of the inductor will decrease as the current increases. This change in resistance can be used to regulate or switch power and is the primary reason why the 1840-28K is so commonly used in power regulation and switching circuits.

In conclusion, fixed inductors such as the 1840-28K are essential components of many electrical and electronic circuits. They are primarily used in voltage-controlled resistors, oscillator and PLL circuits, rectifiers, and field-effect transistors. Their working principle is based on the core material, which is usually ferrite, and they act as magnets that store energy in their magnetic field. This energy is then used to regulate or switch power when an external voltage or current is applied.
