Donau Elektronik 125-051 Cable flexible 1 x 0,25 mm² negro 50 m

For electronics enthusiasts, prototyping labs, and model builders, a reliable hook-up wire is essential. The Donau Elektronik 125-051 delivers a 50-meter spool of fine-stranded copper wire with a 0.25 mm² cross-section, insulated in black PVC. It handles low-voltage signal and control wiring with ease.

Key specifications

• Wire type: stranded (Litze), 7 x 0.2 mm construction
• Number of cores: 1
• Conductor cross-section: 0.25 mm² (AWG 24 equivalent)
• Insulation colour: black
• Length: 50 m on spool
• Conductor material: copper
• Insulation material: PVC
• Nominal voltage: 300 V
• Operating temperature: -20 to +80 °C
• Outer diameter: approx. 1.2 mm
• Conductor resistance: approx. 67.2 Ω/km
• RoHS compliant

Why choose it

Flexible stranding makes this wire easy to route in tight spaces, while the black PVC jacket resists abrasion and common chemicals. The 50-meter spool offers ample length for multiple projects, and the consistent 0.25 mm² cross-section ensures predictable current handling for low-power circuits.

Ideal use cases

• Prototyping on breadboards and perfboards
• Internal wiring of electronic devices
• Model building and hobby robotics
• Low-voltage signal connections
• Repair and modification of consumer electronics

Good to know

The wire is supplied on a convenient spool that prevents tangling during storage and use. It is RoHS compliant, making it suitable for projects requiring environmental compliance. For higher current applications, consider a larger cross-section.
