I can't tell its value, the markings are 224 E5Z
on one side and 038
ASF on the other side.
.. can anyone tell me what value/spec the capacitor has?
Err, was that maybe "Z5E"? I have found this page:

very helpful in deciphering capacitor markings.

That address doesn?t work for me. Z5E sounds like a ceramic capacitor. The usual
interpretation of 3-digit codes is exactly like the 3 colored stripes: read it as
scientific notation. So 224 would be 22e4, or 220k. Capacitors are marked in pF so that
would be an 0.22 uF capacitor. Very plausible for a ceramic bypass capacitor, which is
what Z5E is if I remember right. For a tantalum capacitor, that would be surprisingly
low.

They definitely made 0.22uF tantalum parts. I have some in my parts bins.
They aren't very common though (but neither are 0.22uF electrolytics). A
photo of the original part would definitely help determine if it is a
tantalum or some sort of ceramic. The only thing I'm really finding with a
search for E5Z is a 100V rated monolithic epoxy dipped ceramic capacitor.

Z5E is standard tolerance / tempco / dielectric data for ceramic caps. No
way is that a tantalum, it's almost certainly a ceramic - and 0.22uF is
correct.
