Air Coil Inductor BC

Ferrtx Air Core Inductor coils are designed for applications where linear inductance, low distortion, and stable high-frequency performance are required.
By eliminating magnetic core materials, air core inductors avoid saturation effects and core losses, making them ideal for precision signal and power circuits.

This page focuses on the BC series, which has been separated from the previous mixed product range to provide clearer technical positioning and improved application matching.

What Is an Air Core Inductor Coil

An air core inductor coil uses air as the magnetic medium instead of ferrite or iron powder cores.
This structure ensures excellent linearity and predictable inductance behavior, especially at high frequencies or under dynamic signal conditions.

Ferrtx air core designs are part of our Air Coil Inductors category, optimized for RF, audio, and crossover circuit applications.

air coil inductor formula and Design Considerations

The inductance of an air core inductor is typically determined by the coil geometry, number of turns, and coil diameter.
The air coil inductor formula highlights how physical dimensions directly affect inductance value, making mechanical precision critical in production.

Key design factors include:

• Coil diameter and length

• Number of turns

• Wire diameter and spacing

• Self-resonant frequency

Ferrtx applies controlled winding techniques to ensure consistent inductance and tight tolerances across production batches.

Air Core Inductor Crossover Coil Applications

An air core inductor crossover coil is widely used in audio crossover networks, where signal purity is essential.
Because there is no magnetic core to introduce hysteresis or saturation, air core coils deliver clean signal transmission with minimal distortion.

Typical applications include:

• Audio speaker crossover networks

• Hi-fi and professional audio systems

• Signal conditioning circuits

For RF signal processing, air core inductors also complement RF Inductor solutions where low loss and high Q factor are required.
