Default how to read tantalum caps

I'm getting ready to order more parts for my orion 2150gx and i'm not sure what the value is on the tantalum caps in this amp.I can see they are 25 volt but the value is listed as what looks like 2u2 . I'm not sure if these are 2.2 microfarad or 22 or maybe I'm way off.If somebody could shed some light it would be greatly appreciated.

I'd guess the position of the "u" is the decimal point (2.2uF). Do you know what mfg's cap they are? We could find a datasheet to confirm, or could you measure one of them?

i don't see anything on the caps that would indicate the manufacturer of them.

2u2 is 2.2uF.

"That is just the European notation. They replace the decimal point with the multiplier letter.This prevents the possible loss of the decimal point in transcribing data. For instance, 4.7K = 4K7, 1.2K = 1K2, 1M = 1M and so on.

It's handy, and less error prone."

2.2uF, not 2.2F

They use the unit symbol in place of the decimal. It saves space and is easier to see.
