Default Component Identification

HI All,

Just wondering what you guys make of this. Hard to see in the pic but it reads Uf in the oval. So I thought 4700 uf but seems an odd value. There is also another cap exactly the same with 2220 as the number.

Thanks all

It physically is too small to be 4,700uF, also for that value it would be an electrolytic capacitor which it does not look like.

If it is a capacitor then maybe 4,700pF, the uF in the oval marking maybe a brand marking identification.

What piece of equipment is it from ?

Hi Ed, disc ceramic may only be 50V as writing not clear, bur 4700pF and 2200pF value

Look like two 4n7 or 4700p ceramic caps. Comparing them with the size of the resistors next to them I'd say they were low voltage. The circuit they are in should tell you more as will a quick voltage test.

Yep, 4n7 (4700pF) ceramic. Low voltage type and probably faultless.
