I believe this is a 0.01 uF (10,000 pF) 0.1uF (100,000 pF) 50V +80%/-20% ceramic capacitor?
Just looking to double check the specs to make sure I have this right.
Hmm 10 x 10^4 = 10x10000 = 100,000 pf or 0.1uF. 50volt? tolerance is +80/-20%
here is one chart: https://circuitspedia.com/how-to-read-ceramic … alue-104-chart/
Hate posting a reply and then have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. Stuff: https://archive.org/details/@horun
104 -> 10 x 10E4 pF = 100 nF
H5Z ->
H - the manufacturer code (I think), not sure who uses that.
5 is 50V tolerance
Z would be the precision you listed.
Thanks for correcting the capacitance. For some reason my brain always reads "104" as 10^4. I keep forgetting it's 10 x 10^4. 😓
Even if you cant read markings/part is gone its usually easy to figure out what it was doing. This one is decoupling U16, IC right in front of it, using very old and bad method of routing caps to power planes instead of directly to IC pins. Decoupling caps were predominantly 100nF back in the day as a rule of thumb.
Nowadays decoupling caps are put almost right on vias.
