Capacitor Identification

The numbers seem to read
225
PC
330
4
What does it mean? Someone told me
"225 = 22 x 10^5 pF = 2.2 μF"
with 330 V being the potential rating
"PC" = polymer cap
Is this correct?

yes 2.2uF

it's an electrolytic

I think you will find its 33 D

33V and the D will be a tolerance

I can absolutely, utterly, beyond all shadow of a doubt, guarantee it isn't 330 V

I think maybe this is a Panasonic aluminum capacitor, the first number is lot ID. I think it might be 330 uF similar to these

Data sheet

Unfortunately I think I already ordered the wrong parts. The data sheet at least tells us what each row means but doesn't tell us how to interpret "R. Capacitance"

My attempts to actually measure the capacitance have failed (my meter showed 41 nF I believe).

Yup, good call, looks like I was mistaken :smile:
that top row is the lot #

but doesn't tell us how to interpret "R. Capacitance"

well that's easy .... it's a general electrolytic type, the capacitance is in uF .... you wont find that style in pF or nF

so 330uF

I just don't see how to relate the bottom line "4" to the voltage rating tho ??
