Fake ELNA electrolytic smd capacitor
The RVT on the caps does not mean it is RVT series capacitor. It is some sort of code which tells something about the caps to the manufacturer, like factory, year, lot, etc.
So you don't have fake Elna RVT capacitors.
If you bought a &quot;pack of capacitors&quot; with only info about capacitance and voltage rating, then you have a pack of random capacitors with no info to determine the manufacturer or any specific information about them.
