Ilmainduktorit
An air-core inductor, here represented by the Estonian term ilmainduktorit, is an inductor that lacks a magnetic core. It consists of a coil of conductor wound on a non-magnetic former, with air as the magnetic medium. The absence of a ferromagnetic core eliminates core losses and saturation effects, making these inductors favorable at high frequencies.
Inductance is determined mainly by the coil geometry: the number of turns, the cross-sectional area, and the
Applications include RF filters, tuning circuits, impedance matching networks, and laboratory test setups. They are preferred
Variants exist, including air-core solenoids, and air-core coils with various geometries. The performance of ilmainduktorit depends
