Does anyone know the date codes that Mallory uses on their electrolytic
caps a 1900ufd at 450v? Here's a couple of lines..

If I'd have to guess, Hank, I would say that cap was made in the 12th
week of 1981. That's according to the last 4 digits.

I have three screw terminal Mallory caps with the following markings:

30000MFD 15VDC
POS + 85C
MAX SURGE 20VDC

21000MFD 16 VDC
POS + 85C
MAX SURGE 20 VDC

They all date from around the early 80s.

Here they are pictured among Sprague caps of the same vintage:

I'd say that 8112 is a YYWW date code.

It is a YYMM date code. I have several pieces of vintage medical electronics
equip, and the date codes on the Mallory caps all match closely the date
codes on other parts.

This one is from Feb 1982 - and it's Kosher too. ;-)

Remember Sprague's motto?
Don't be vague, ask for Sprague.

a little levity . . . very little . . .

Then how do you account for the "32" in "235-8532K"?

Here are two more caps, with date codes of 7945 and 8102:

It IS YYWW (that is year and week)
so....235-8532 means 1985, 32nd week. That is why the K is there...

I agree that it is YYWW, but I don't understand what you are saying the reason
is that the "K" is there? Why is the "K" there?
