I have this capacitors and I tried learning how to read them but I am still unsure. I believe these are 330uf 16v capacitors but I dont know what the 282 means. Or if I am even correct.
What do these markings mean?
I would agree its a 330uF 16V capacitor. The 282 appears to be a production or lot code.
The information is found in datasheets, so you would need to determine the manufacturer and series to be sure.
Just as an example. Here is a snippet I took out of a datasheet for a capacitor with similar markings. The brand in this example is Cornell Dubilier.
