Self-Supporting Coils

Precision wound self-supporting coils, also known as air-core coils, maintain their shape without a bobbin or core material. Sizes range from 0.015 inches to 4 feet in diameter. Wire sizes range from #4 AWG to #56 AWG.

Advantages of Self-Supporting Coils

Save space in compact designs

Improve performance in high-frequency applications

Provide durability in demanding environments

Miniature Self-Supporting Coils

With technology evolving at lightning speed, precision in electronic manufacturing is not optional: it is a necessity. As products continue to shrink while demanding greater performance, components must be optimized for miniaturization without sacrificing reliability. Able Coil delivers custom miniature coils that meet tight tolerances — down to the size of a ballpoint pen tip — manufactured with ultra-fine wire as small as #56 AWG.
