Jaycar 0.25mm Enamel Copper Wire Spool – 30 B&S Gauge for Chokes & Crossover Coils

You're winding a choke or building a crossover coil and the wire gauge has to be exact. Too thick, your inductance is off. Too thin, it won't hold current. This 0.25mm enamel-coated copper wire (30 B&S) comes on its own plastic reel so you can wind neat, tight layers without tangling a loose strand. At 25g on the reel, it's a practical quantity for a single project or a small batch of classroom components. Grab it, wind what you need, and the rest stays clean in the drawer for next time
