Donau Elektronik 210-10 Litz Wire 2 x 0,04 mm² sarkans/melns 10 m

7 x 0,1 mm tinned copper conductors in each 0,04 mm² core — that's what makes this Donau Elektronik litz wire bend and flex where ordinary hook-up wire kinks and breaks. The red/black PVC jacket keeps polarity obvious, so you spend less time tracing wires and more time finishing the job.

Why it works for tight builds

Each core is built from seven thin strands (7 x 0,1 mm), which gives the cable excellent flexibility — it threads through narrow enclosures, hinges, and model fuselages without fatiguing. Tinned copper resists corrosion and solders cleanly even after storage. The PVC insulation handles abrasion and provides good dielectric strength, while the two colour-coded cores let you identify signal and return lines at a glance. Rated for 30 V and operating temperatures from -20 to +80 °C, it covers most low-voltage work.

Who it suits

• Model builders and RC hobbyists routing wire through moving parts
• Electronics prototypers who need thin, flexible signal runs
• Makers wiring sensors, switches, and low-voltage LED strips
• Teachers and students working on educational circuits

How to use it

Strip the PVC carefully — the strands are thin, so use a proper stripper or gentle heat rather than a knife. Twist and tin the exposed strands before soldering to keep them together and ensure a solid joint. For connections that will move, add a short length of heat-shrink tubing over the solder point for strain relief. The 10 m spool gives you plenty of length for multiple projects; keep it wound and stored dry to protect the insulation.

Tip: Because the conductors are tinned, you can solder directly without extra flux in most cases. If you need to extend a run, stagger the joints between the red and black cores so the finished cable stays slim and won't snag.
