Description
Overview
Red enameled magnet wire in 100g spools for winding coils, chokes and machine windings. It is QA-1-155 grade copper in twenty diameters from 0.05mm to 1.2mm, covering fine instrument coils through to motor work.
Specifications
- Material: copper with red enamel coating
- Grade: QA-1-155
- Weight: 100g per spool
- Diameters: 0.05 to 1.2mm in twenty steps, one size per spool
- Use: coil winding, inductance, electric machine windings
Purpose
Winding needs one known wire size in a workable quantity, since the diameter sets how many turns fit a bobbin. Buying by weight in a single size avoids running short mid-coil.
Applications
- Inductor and choke winding
- Transformer and solenoid coils
- Motor and generator rewinds
- Pickup and sensor coils
- Relay and electromagnet coils
How to Use
- Pick the diameter from your turn count and bobbin window, not the spool size.
- Wind under light, even tension and keep the layers flat.
- Strip the enamel only at the ends, leaving the winding film intact.
- Meter for continuity and for shorts between turns before installing.
- Caution: the film is thin, so avoid sharp bends and abrasion at the coil edges.
