Donau Elektronik koperlakdraad LD10-1, buitendiameter 0,10 mm, 100 m rol

Winding a small transformer or repairing a miniature relay coil? This 100-metre roll of Donau Elektronik enamelled copper wire LD10-1 gives you a precise 0.10 mm outer diameter including the insulating lacquer, so you can count on consistent turn spacing and tight winding. The solderable insulation strips cleanly at the point of contact, making termination fast and reliable.

Key specifications

• Outer diameter (including insulation lacquer): 0.10 mm
• Length: 100 m
• Conductor material: copper, enamelled
• Insulation: solderable polyurethane lacquer
• Model: LD10-1
• Brand: Donau Elektronik

Why choose it

The thin 0.10 mm profile suits fine-winding jobs where space is tight and precision matters. The lacquer coating offers reliable electrical isolation while remaining easy to remove with a soldering iron, reducing the risk of nicked conductors. A 100-metre spool covers multiple prototypes or repair tasks without frequent reordering.

Ideal use cases

• Rewinding small motors, relays, and solenoids
• Building custom inductors and transformers for hobby electronics
• Repairing headphones, loudspeaker voice coils, and sensors
• Prototyping RF coils and antenna matching networks
• Educational lab work and STEM projects

Good to know

Store the wire in a dry, cool place to preserve the lacquer's flexibility and adhesion. When soldering, set the iron temperature between 370 °C and 400 °C for fast, clean insulation removal without damaging the copper. Always verify the final outer diameter with a micrometer if your application has tight tolerance requirements.
