Fixed Inductors play an important role in electronics applications that involve electrical current flowing through them. They rely on the principle of magnetic induction to produce a current or voltage in response to an applied current. A very common type of Fixed Inductors typically used is the 2890-28G Inductor, which is often found in commercial products such as TV sets, stereos, audio receivers and more. These Inductors are especially suitable for low frequency, high current applications.

The 2890-28G Inductor is composed of a copper wire that is wound around a core such as ferrite or iron. This coil is called a fixed inductance because its inductance does not vary with changes in the applied current. A low-value resistor is also usually added in parallel with the inductor to further enhance its stability. A high-value capacitor is then added, usually in parallel with the resistor, to smooth out any voltage fluctuations.

The working principle of the 2890-28G Inductor is based on the core material it is wound around. When a current passes through the inductor, a magnetic field is generated. This magnetic field will cause the core material to resonate, creating a “ringing” effect. During this process, the magnetic field will cause a voltage to be induced in the core, which in turn induces a current in the inductor. As the current passes through the coil, the inductance increases at a fixed rate.

The 2890-28G Inductor can be used in a wide range of applications, such as power supplies, AC/DC converters, inverters, voltage regulators, stepper motors, and applications using digital signal processors, among many others. It can be used to regulate voltage for safety purposes in sensitive equipment, or to switch power from a voltage source to ensure a smooth, reliable, and efficient current flow.

The size and type of the core material, as well as the number of turns in the coil and the size of the resistor, will determine the inductance values of the 2890-28G Inductor. The larger the number of turns, the higher the inductance value and the greater the current flow. On the other hand, the higher the value of the resistor, the lower the inductance value and the lower the current flow.

In summary, the 2890-28G Inductor plays an important role in a variety of applications, especially those that require a low frequency, high current. It is composed of a coil wound around a core material, with a resistor and a capacitor connected in parallel to help manage voltage fluctuations. Its inductance values are determined by the type of the core material, the number of turns in the coil, and the size of the resistor. Its working principle is based on the principle of magnetic induction, whereby a current creates a magnetic field that induces a voltage in the core material, which in turn induces a current in the inductor.
