Subject: RE: [motm] 510 Parts Question...

From: "Adam Schabtach" <adam@...>

To elaborate slightly on what Paul said:
 
1) cap colors are (almost always) irrelevant and change with the manufacturer and other random influences. I don't know of any instance in which the color of an electrolytic cap is meaningful. It's the capacitance and voltage ratings (and the physical shape) which are relevant. Other cap types seem to be differentiated by color but again this varies from one manufacturer to another and cannot be depended upon.
 
2) I think B.P. designates Bi-Polar, which is another way of saying non-polarized. I developed this theory last time I ordered non-polarized caps, but it's only a theory.

Of course they are correct.

Subject: [motm] 510 Parts Question...

I'm going through the parts received with the 510 kit and I noticed some discrepencies with the capacitors.
 
1) The 10mfd 50V (polar) electrolytic caps (C4, C8, C15, and C16) are supposed to be orange according to the installation instructions. Mine are black with a grey stripe on the negative side. Mine are labeled as 10uf50v B0613 PET VZ(M). Are these okay?
 
2) The 10mfd 50V non-polar electrolytic caps (C1, C3, C5, and C13) are supposed to say NP on them (I'm assuming to indicate that they are non-polar). Mine are blue'ish, do not have a stripe (however they do have a long lead and a short lead), are identified as 10uf50v B.P. 64IOT, and do not say NP. Are these correct?
 
Thanks,
Jim
