Hello,
I'm having difficulty sourcing barrel connector sockets rated at >5A, which is bizarre as numerous reputable suppliers sell 12V/10A desktop PSUs that terminate in a 5.5mm OD / 2.5mm ID barrel plug. Yet, no matter how much searching I do I can only seem to turn up 2.5A rated sockets and, at a push, 5A rated.
Grateful for any suggestions or insights anyone can offer here...
Cheers,
Andrew
Hi Andrew.
Can you provide a few component examples that didn't quite work in terms of ratings?
cheers, saar.

Hi Andrew,
I had a quick search and agree that 5A is about the maximum specified rating.

It will probably be a result of contact area - especially the outer contact that wipes the barrel, contact material and flammability rating of any plastic parts.
I guess these were designed for low power and low manufacturing cost - and anything that uses 12V at >5A is barely considered low power these days.

Yes, those barrel connectors with yellow insulator usually have two wipers to touch the centre pin (whereas the default is that it touches the inside of the barrel along one side) and the socket for these found on laptops also has several wipers around the outside. I've seen plenty of laptop PSU sockets for sale as replacements on e-bay and one of those is probably best.
