I'm attempting to fix some old tube radios for a friend.

I ordered some caps, but the numbers don't jive.
For example, 5 of them are .05 MFD, 200v;
But I received (5) .047's, at 600v. (I get that one)

Another one was a .03 MFD, @ 400 VDC, but I think I received a 333K @ 600V. (does that sound right?)

Some of the new caps don't show the uF value, but rather show only the volts and the ohms value, such as 333K, 154K, 102K, 103K, etc.

So I'm looking for a way to cross reference these numbers to see which ones replace which.

The guy that sold me the caps told me he gave me what I asked for.
In fairness, he gave me an explaination of sorts, but I would much prefer to see a table.

Thanks,
Gary

 

Hello,

The 333 wil mean 33 X 10³ = 33000 pF = 33 nF = 0.033 μF.
The K stands for the tollerance of ±10%.

Besides the somewhat understandable confusion, could you measure them to convince yourself?

Just check if you DMM can do that. If so, no table needed.

 

Perhaps this might be of some help.

 

You guys are awesome.
Thanks,
Gary
