Air Coils Inductors, Spring Coils (TCAC)
Direct manufactures all types of air coil inductors. Air Core Coils' another name is Spring Coils. Direct's Air Core Coil (TCAC) Series has advantages of free from iron losses, non-linearity, single layer coils structure, low self-capacitance, and self-resonant frequency.
TCAC's inductance is unaffected by the current it carries. This contrasts with the situation with coils using ferromagnetic cores whose inductance tends to reach a peak at moderate field strengths before dropping towards zero as saturation approaches.
Sometimes non-linearity in the magnetization curve can be tolerated; for example in switching converters. In circuits such as audio cross over networks in Hi-Fi speaker systems you must avoid distortion; then you need an air core coil.
Most radio transmitters rely on air coils to prevent the production of harmonics.
Direct's (TCAC) Series is custom coil windings. Please call Direct Sales for your requirements to have high quality work at a reasonable tooling cost and low cost volume production.
