## Summary description

Copper wire UN, diameter 0.3 mm, length 10 m, black insulation. Single conductor copper wire suitable for electronics, prototyping, wiring small devices, model making and craft work. Provides a thin, flexible conductor for low-current signal connections and repairs where precise routing and compact bends are required.

## Long description

Copper Wire UN 0.3 mm, 10 m, black is a thin insulated copper conductor designed for electronics, prototyping, model making and craft applications. With a 0.3 mm conductor diameter and 10 m length, this black-insulated single-core wire offers fine routing for low-current signal connections, small repairs and compact installations where space and flexibility are important.
Advantages
The wire combines high electrical conductivity of copper with a slim, flexible insulated jacket that supports precise bends and neat routing in confined spaces. Its insulation provides basic protection against short circuits and mechanical abrasion typical for light-duty electronic assemblies and hobby projects. The 10 m length supplies sufficient material for multiple small runs while keeping handling and storage simple.
Suitable for
Prototyping and breadboard wiring for low-current signal lines
Model making and scale electronics in hobby projects
Repairing small consumer devices and circuit boards
Craft projects requiring thin, flexible conductive leads
Key specifications
Conductor material: copper
Conductor diameter: 0.3 mm
Insulation: single-core insulated jacket (black)
Length: 10 m
Intended use: low-current signal and small power connections
How to use
Strip the insulation carefully to expose the copper conductor, using an appropriate stripping tool or sharp blade with fine control. Route and secure the wire to avoid sharp bends and stress points; solder joints should be made with moderate heat to avoid damage to the thin conductor. For temporary connections, use fine alligator clips or breadboard posts; for permanent installations, secure with adhesive or cable ties and insulate exposed joints with heat-shrink tubing or insulating tape.
Usage recommendations
Use this 0.3 mm copper wire for low-current signal lines and delicate wiring where flexibility and small bending radius are required. Avoid using it for high-current applications. When soldering, apply minimal heat exposure time and ensure good mechanical support at joints to prevent conductor breakage.
