!!!!!!!!!!!!!
Are they? Their order is a bit strange if so.
On the other hand, take the - to be a 1, and the other symbol to be a 4
with a bit missing,
This is how right-pondians write the numeral "1". They also cross their
"7"s. ;-)

It has no polarity markings. One terminal is common with the metal case. Is
this always an indication of the (-) terminal?
The base has molded terminal locations numbered 1-4, two of which are empty:

Markings on the side are:
B41111-B7108-T
1000uF 40V-
GERMANY
GPF DIN 41332 06.78
I find a few references to a Siemens part that is similar:
http://www.screenghost.com/shop/show.asp?ID=74#
but no datasheet can I find. Can someone more resourceful than I find one?
I cut open one of these caps. It is paper & foil (or so it seems) spiral wrap
construction. Can polarity be determined by internal construction? Is the
center terminal always one pole (ie, always +)?
Thanks.

How is it wired in the circuit? When in doubt, this is what I look at.
You can also substitute it with an AC rated cap and just measure the
voltage across it to find out which way around it should be. |

** Bullshit.

** Yep.

empty:

** Are you totally blind ????
The usual cause applies ?????
FYI:
The markings are clearly 1, 2 and 3 with the fourth a NEGATIVE sign
!!!!!!!!!!!!!
Is not the negative sign *right next* to the pin linked to the case ?????
.... Phil
For modern capacitors, yes, *BUT* there were some chassis-mounted[/quote]
caps with POSITIVE (outside) cans/cases. |

To me they look like "1" (not a "-"), "2", "3", and a really weird "4".

But with your help along with the one pin (yes, it's the (-) one) in common
with the case pretty much confirms polarity.
Thanks!
Nighty-night! Lights out!
Ahh but it's german. They make the 1 with that little hat.
[/quote]
[quote]And then
when they make a 7 they always add a cross through the middle... so as
not to confuse it with the one.
The Germans (and those in many other Continental European countries)[/quote]
certainly do that when WRITING the number 7. However, I can't recall
ever seeing it on a PRINTED 7. This is (of course) because they start
writing a 1 (one) with a long slanted up-stroke, followed by a vertical
down-stroke. As such, it's not unlike an 'artistically' written 7. The
addition of a horizontal stroke through the vertical down-stroke of the
7 prevents it from being confused with a 1. With a printed 7, the top
stroke is definitely horizontal, and there is no confusion.
Most non-Europeans write a 1 (one) as a single vertical down-stroke, so
there is no possibility of confusion between a 1 and a 7. However, if
you decide to embellish a 1 with the short slanted up-stroke at the top
and the foot at the bottom, you have to be careful that it cannot be
confused with a 2.
