Help identifying a blown cap

[walkabout]

I'm new to the forum and not much of an electrical whiz. I run a small WISP in Utah and I use Mikrotik/Routerboards all over my network. They are great devices with horrible capacitors in them. I have had this problem when the boards are powered with a wall wart as well as POE, indoors and outdoors. I've tried contacting Mikrotik regarding the capacitor problem but have not gotten far. I'm hoping to find some answers here. I have pictures of the capacitor and one of the offending boards. I am looking for two answers.

1. why do these caps keep failing?
2. What cap would be a better choice for replacing the blown ones.

Welcome to Badcaps!
Quick answers (I'm suppose to be working...)

1 - Su'scon are absolute crap caps.
2 - Panasonic FM series.

And don't forget to crack open the wall warts too.

Re: Help identifying a blown cap

The Su'scon is a 560uF 6.3v capacitor. You can replace with 560uF 6.3-16v capacitors (capacitors with bigger voltage rating can be used with no problems at all)

Replace with Panasonic FM or Panasonic FR series capacitors.

FR series handle heat a bit better but even FM would be much better than what's used now. As mockingbird says, double check the wall warts as well.

Thank you for your quick replies. I can't check the wall warts. They're at the metal recyclers.

What are you going to use instead?

If I use it for a point to point I'll inject power.
