Jaycar 0.5mm Enamel Copper Wire Spool – 100g for Chokes, Coils & Power Applications

When your project needs to carry real current – a power choke, a toroidal transformer secondary, or a beefy crossover coil – you need wire with the cross-section to do it. This 0.5mm enamel copper wire is the next step up in gauge, and at 100g on the reel you've got enough for a proper multi-turn wind without running out halfway through. It comes on its own plastic reel so every layer sits clean and parallel. Whether you're in the workshop or setting up the school electronics bench, this is the spool that gets the job done without a mid-project trip to the store

• 0.5mm enamel-coated copper wire for higher-current chokes and coil winding
• 100g per spool – enough for multi-turn projects without running short
• Supplied on a dedicated plastic reel for clean, parallel layer winding
• Suitable for power chokes, transformer windings, and crossover coils
