Enamelled Copper Wire - 0.5mm (Sold Per Meter)

High-Purity Electrolytic Tough Pitch (ETP) Copper Core

Engineered for high-performance electrical engineering, custom inductive component design, and precision coil winding, this 0.5mm nominal diameter enameled copper wire features a 99.9 percent pure Electrolytic Tough Pitch (ETP) solid copper conductor core. Delivering exceptionally low DC electrical resistance of approximately 0.088 Ohms per meter at 20 degrees Celsius, this wire maximizes current carrying capacity while minimizing I2R resistive heating losses. The high-purity copper processing eliminates internal voids and micro-structural impurities, ensuring consistent conductivity, superior ductility, and high mechanical tensile strength under rapid spooling and high-tension automated winding operations.

Solderable Polyurethane (UEW) Dielectric Insulation

The conductor is coated with a precision-extruded, uniform layer of Class 155 polyurethane enamel dielectric insulation. This modified polymer film delivers exceptional breakdown voltage protection exceeding 1500V RMS, preventing turn-to-turn short circuits and insulation degradation in high-density, multi-layer magnetic coils. Engineered with thermally strippable properties, the enamel coating sublimates cleanly at soldering iron temperatures between 360 degrees Celsius and 400 degrees Celsius. This self-soldering feature eliminates the need for mechanical wire stripping, chemical solvents, or abrasive scraping, guaranteeing fast, reliable, and oxidation-free solder connections at termination pads, headers, and terminal posts.

Optimized for Precision Magnetic Component Fabrication

With an ideal balance of cross-sectional area and bend radius flexibility, this 0.5mm magnet wire is tailored for fabricating custom toroidal inductors, switch-mode power supply (SMPS) transformers, RF chokes, solenoids, and magnetic levitation coils. Its tight outer diameter tolerance ensures a high copper fill factor inside ferrite cores and bobbin windows, maximizing magnetic flux density and overall coupling efficiency. The smooth, low-friction enamel surface prevents snagging and micro-abrasions during complex hand winding or bobbin layering.

Advanced Electronic Prototyping and Board-Level Repair

Beyond inductive components, this magnet wire serves as an indispensable tool on the electronics rework bench. The ultra-thin yet resilient dielectric film provides high spatial isolation, making it ideal for fine-pitch PCB jumper modifications, high-density trace repair under BGA components, custom sensor array fabrication, and prototyping experimental electromagnetic actuators. It is equally suited for academic physics laboratories, robotic motor stator rewinding, guitar pickup manufacturing, and high-frequency audio crossover networks.
