Thank you for your inquiry and welcome to the community.

I couldn’t find any capacitors we carry that match that part marking format.

I’m pretty sure that is a 22uF capacitance. If you could provide diameter and height measurements that would help provide clues on what voltage it might be.

This part isn’t showing typical markings to indicate its rated voltage.

If you could figure out what the voltage is that the positive side of the capacitor sees, that would also help to narrow down the options. It should be rated for _at least_ 30%, and preferably 50% or more above that level.

Ok some additional info

Diameter - 4mm

Height - 5mm

I actually tore the faulty unit apart and there is a 7805 next to it, so I’m assuming this gets 5vdc. Slightly different marking on this cap

Hmmm, still can’t ID it, but it has to be at least 6V then. That’s likely what the lower “6” represents.

[Here’s a link](https://www.digikey.com/short/jbpp5hhv) to some parts that would physically fit, and which are at least 10V at 22uf.

Excellent, thank you so much for the help and quick replies!
