Following on from what DaveM has said, here is the datasheet for the
Vishay Sprague 53D series:
http://www.vishay.com/docs/42037/53d.pdf

"Vishay Sprague 53D series is a general purpose capacitor with a
rugged construction and the largest CV ratings in axial leaded
capacitors. These axial leaded aluminum capacitors feature a rated
capacitance range of 15 �F to 220,000 �F, and an operating temperature
range from - 40 �C to 85 �C."

Rated voltage range, UR 6.3 WVDC to 450 WVDC

Unfortunately the datasheet doesn't show a 60,000uF cap. The largest
is 11,000uF. Furthermore, the capacitor markings only appear to make
sense for the first line.

Judging by your dimensions, if by "wide" you mean "long", and by
"thick" you mean "in diameter", then a 60,000uF cap in the 53D series
would be much longer than 2", I would think.

For example, a 3800uF 50V cap is 2.14" long and 1.01" in diameter.
What voltage could you expect of a 60,000uF cap of the same size?

Franc, Sprague didn't use the three digit code to identify yhre
capacitance. It identified the part numer in the series. Someone on the
antiquie radio nesgroups or forums may have an old catalog. I can't
find mine right now. I can barely see at all, and am not epxpected to
recover, for several months.

Totally valid arguments and I agree with you after being reminded that the OP
had given the dimensions of the cap as 2x1 inches. I overlooked that aspect
after my first read of his post.

The lack of any numbers after the first line (53D603) threw me at first, but I
remembered that Sprague used to make the 53D line. I just figured that the OP
had an old unit and used a capacitor value that had been obsoleted.

Cheers!!

A picture might help.

If it is Sprague, their 'trademark' is a '2' with a circle around it.
Called the 'circle duce', it stands for 'second to none'.

I used to design and build monolithic capacitors and resistors for Sprague
in the late 60's and early 70's.

As far as I know, we never made anything over a few dozen uF at our plant
in Wichita Falls, tx.

I forgot to mention that the customer had brought in two of these units,
one being a bit newer than the other. The other unit happened to be in
working order, so I opened it up and found a similar design with another
strangely-marked cap. But since it was working, all I had to do was measure
the operating voltage and capacitance. The voltage across it was about
320VDC, and the capacitance was just 1.18uF. This cap, unlike the one in the
other unit, appeared to be a non-polarized metal-film type. So I installed a
2.2uF, 400V metal-film cap (the closest thing I could find) in the other
unit and it appears to work. Both units create a good thick spark of about
1/8". So I guess the problem is solved. BTW these units are not terribly
old, both have mfr'd dates in the early 90's.
Thanks anyway for your help.
