DC barrel connector pigtails for LED

These ten 30 cm pigtails terminate in a 5.5 mm by 2.1 mm female barrel plug. Pure copper conductors rated at 10 A suit DC power feeds to LED strips, CCTV cameras or small monitors. The 18 AWG wire uses a 12 by 0.12 mm strand layout for flexibility in tight cable runs. Each pigtail is ready to solder or crimp to an existing supply lead.

10 A current rating on 18 AWG copper

The single figure that decides fit is the 10 A rating carried by 18 AWG conductors. If the load draws more than 10 A the wire will overheat; if the device needs a different barrel diameter the plug will not mate. The 5.5 mm outer and 2.1 mm inner dimensions must match the jack on the target equipment exactly. No other specification in the data changes compatibility.

Steady 10 A load with minimal voltage drop

Under sustained load the pure copper core holds its rated 10 A without the temperature rise seen in thinner aluminium alternatives. The 4.5 mm outer jacket protects the 12 by 0.12 mm strands from abrasion during long-term installation. Voltage drop over the 30 cm length stays low enough for stable LED brightness and monitor operation. The pigtail is not designed for repeated flexing or high-cycle connector mating.

Questions about this item

What does the 10 A rating mean when I plug this pigtail into my device?

The 10 A rating is the maximum continuous current the pure copper cores can carry without overheating, so the connected power supply and load must each stay at or below 10 A.

How does the 5.5 mm × 2.1 mm barrel size limit what I can connect?

The 5.5 mm outer diameter and 2.1 mm centre pin only mate with matching DC jacks; any plug with a different pin or barrel dimension will not seat securely.

What clearance do I need for the 4.5 mm cable and 30 cm length when routing it inside an enclosure?

Allow at least a 5 mm wide channel for the 4.5 mm jacket and plan for 30 cm of free run from the jack to the connection point.
