A capacitor in a power supply exploded. It is 2200uf 25v. I attached a photo of the other side. Is this just a "standard" capacitor?

Thanks

Looks like a fairly ordinary aluminium electrolytic capacitor to me.

I assumed CR is a brand but I have not been able find what CR stands for so I could determine what the other info meant

I found a reference to a "CD11" series capacitor from a few sources, all mainland China stuff. There's a "Ningbo Zhengming Electronic Co., Ltd.", for example, that claims to "manufactures aluminum electrolyze capacitor of the brand of "Cirony", "CR", including CD11 model series..."

Do a search of "capacitor cd11" and you'll find that they're "consumer" grade parts, +/-20%. The markings on yours suggest -40 to +85oC. I think any decent 2200/25 electrolytic would be fine there. You might upgrade to a 105oC part if the one that popped is near parts that get hot...

Thanks, that is what I thought. I just like a second opinion.
