Air Core Inductors:

499 Products Found
We offer a range of Air Core Inductors with choices of inductance, RMS current, and inductance tolerance.An Air Core Inductor does not depend upon a ferromagnetic material to achieve its specified inductance. Instead, it comprises windings coiled onto an insulator such as Bakelite, glass, or PTFE, with only air inside the coil.One of the biggest advantages of an air core inductor is the minimal signal loss that occurs at higher magnetic field strengths. With ferromagnetic cores such as iron, the core can become magnetically saturated when the magnetic field is too strong. This leads to a loss in inductance, but an air core inductor has no such problem. An air core inductor can carry electromagnetic frequencies up to 1 GHz, but ferromagnetic core inductors tend to experience loss when the frequency exceeds 100 MHz.Air core inductors are also free of the 'iron losses' which affect ferromagnetic cores. As frequency is increased this advantage becomes progressively more important. You obtain better Q-factor, greater efficiency, greater power handling, and less distortion.

Applications for Air Core Inductors

Sometimes non-linearity in the magnetization curve can be tolerated; for example, in switching converters. However, air core inductors are essential in circuits such as audio cross over networks in hi-fi speaker systems that must avoid distortion.Most radio transmitters rely on air coils to prevent the production of harmonics. As well as their use in constructing RF tuning coils, Air Core Inductors are also found in filter circuits, snubber circuits, and high-frequency applications including TV and radio receivers.
