Unique-Bargains Enameled Copper Wire 0.25mm 49ft 130°C

Hobbyist winding wire

This 0.25 mm enameled copper wire suits hobbyists, students and small-shop technicians who wind their own coils, transformers or motor windings. The polyester insulation with polyamide overcoat prevents turn-to-turn shorts while remaining thin enough for tight windings. A 49 ft spool provides enough length for multiple experimental or repair jobs.

130 °C thermal headroom

The wire is rated for continuous operation at 130 °C, giving ample margin for typical low-voltage winding tasks that run well below that temperature. The 0.25 mm conductor diameter limits current-carrying capacity, so the wire reaches its thermal limit quickly in high-current or high-duty-cycle applications.

Solderable insulation frees flux time

The modified polyester insulation can be soldered through with a hot iron, removing the need for mechanical stripping and speeding up prototype assembly. The fine 0.25 mm diameter demands a steady hand and fine-tip iron; builders needing heavier gauge or higher current capacity will find this spool insufficient.
