As there is no magnetic core, they do not suffer from operating losses due to the hysteresis, eddy current, or distortion common in magnetic cores. These inductors have low nominal values of inductance but offer a high-quality factor. These are solenoidal coils that use a non-magnetic core and can have a single loop of wire to large coils depending upon the range of frequency they are designed for. Some other widely used inductor types are presented here.Īir Coils – Air coils are the simplest inductors. We have already discussed some of the inductor types, such as solenoidal coils, toroids, pot cores, and transmission line inductors. So, choosing an inductor is quite simple compared to resistors or capacitors (which have a lot of options for any given application). Manufacturers supply inductors for application-specific categories including RF chokes, power, high current, and high-frequency. These specifications are useful in determining the efficiency of an inductor in a circuit. In the previous tutorial, we learned about the different properties and characteristics of Inductors.
