Applications of Litz Wire (With or Without Serving)
To complete the picture, here are the core applications of litz wire itself, which may use other insulations (like silk, cotton, or just heavy enamel) if a nylon serving isn't present:
Any high-frequency inductor where efficiency is paramount.
RF coils in amateur radio and broadcast equipment.
Ferrite rod antennas in AM radios.
Pickup coils in metal detectors.
Magnetic resonance imaging (MRI) gradient and shim coils.
Applications of Nylon Serving on Other Wires
Nylon serving isn't exclusive to litz wire. It's widely used on:
Magnet wire in general transformer and motor windings for added durability.
Hook-up wire in electronics for abrasion resistance.
