Fixed Inductors

The AISM-1812-221K-T is a specific type of fixed inductor, which is a passive two-terminal electrical component that stores energy in a magnetic field when an electric current is flowing through it. Inductors are commonly found in power supplies, telecommunications, and industrial applications, among others. This particular fixed inductor features a Ferrite-Core material and standard tolerance, a maximum DC resistance of 0.003 ohms, and an inductance of 0.22 micro Henries.

Fixed inductors are able to serve many purposes, chiefly in the area of electrical and electronic components. In terms of electrical components, they are used to provide inductance and impedance to any system. This waveform shaping can be utilized to allow AC (alternating current) signals in the presence of DC (direct current). Additionally, fixed inductors can be used to keep a system’s noise level down, preventing the periodical over-voltage spikes that are typically caused by inductive loads. They are also used for filtering circuits, which serve to only allow certain frequencies to pass through and block others. Finally, as part of signal processing, fixed inductors can be used to separate two signals, helping to attenuate one of them completely.

When an electrical current is applied to the AISM-1812-221K-T, the inductance forms a resistive voltage drop across the inductor, expending stored energy from its magnetic field. However, due to the material of the inductor, the voltage cannot be greater than the initial voltage, resulting in the conversion of AC to DC while allowing two signals (one longer than another) of different frequencies to pass through. As a result, the alternating current of the longer frequency will be attenuated, while the lower frequency signal will move on.

The AISM-1812-221K-T are also very reliable and present superior power handling characteristics along with a low ESR rating. Thus, this specific fixed inductor is capable of withstanding harsh environments with temperatures ranging between -40 and 125 degrees Celsius. Furthermore, the inductor eliminates cross-talk from adjacent wires as well as over-voltage and current surges.

Given its ability to both store energy in a magnetic field and present excellent reliability, the AISM-1812-221K-T’s application field is quite expansive and includes consumer electronics, medical equipment, telecommunications, and many more. The working principle of this specific fixed inductor is based on its ability to form a resistive voltage drop across its body and expend stored energy from its own magnetic field in the presence of an electrical current.
