ilmanydininduktorit

Ilmanydininduktorit, also known as air-core inductors, are a type of inductor that lacks a ferromagnetic core. Instead, the coil of wire is wound around a hollow form or simply self-supporting. This design choice significantly impacts the inductor's characteristics.

The absence of a magnetic core means that air-core inductors have a lower inductance value compared to inductors of similar physical size with iron or ferrite cores. However, they also exhibit lower core losses, particularly at high frequencies, which makes them suitable for applications where efficiency is paramount. Another key advantage is the absence of magnetic saturation. Unlike iron-core inductors, air-core inductors do not experience a reduction in inductance as the current increases, ensuring more predictable performance.

Air-core inductors are often employed in radio frequency (RF) circuits, filters, oscillators, and tuning circuits. Their non-linear behavior is minimal, and they possess a higher self-resonant frequency due to the absence of a high-permeability core. The construction can range from simple hand-wound coils to more complex, precisely wound structures for demanding applications. The inductance of an air-core inductor is primarily determined by the number of turns, the diameter of the coil, and its length.
