Enamelled Copper Wire 0.25mm 33swg 548g Spool
Multicomp Pro 0.25mm enamelled copper wire (33swg). Self-fluxing, PU-coated, for prototype coils. Conforms to BS4520. 548g spool.
The Multicomp Pro Enamelled Copper Wire is a high-quality, polyurethane-coated, self-fluxing wire specifically designed for creating prototype coils. Its construction makes it an essential component for hobbyists, engineers, and technicians working on electrical projects, transformers, solenoids, and inductors.
This wire features a transparent polyurethane (PU) jacket that provides excellent insulation and durability. The self-fluxing property simplifies the soldering process, as the coating burns away cleanly when heat is applied, leaving a ready-to-solder copper surface. It is manufactured to conform to the rigorous BS4520 Grade 2 (BS6811 Section 1, Pt.3) standard, ensuring consistent quality and performance for professional and educational applications.
