Does "VELKOD" mean anything to anyone? 4

[jjengel]

Hi all. I've been working on translating some BOMs for PCBs that were originally designed in Germany and have a two Tantalum caps with footprints listed as "VELKOD". Does that mean anything to anyone? I've Google-language-tooled it as well as a general Google search and keep coming up blank. The actual footprint is 7343-31, so I'm not stuck...just curious about what that word may mean.

Anyone?

Thanks,

Jason

VELKOD makes no sense.
ELKO would be the abbreviation for electrolytic capacitor in German.
Are you certain the V and D belong there?

Benta,

I can't say that the V and D belong there, but I can say for certain that they are there. In three BOMs this appears a handful of times exactly as I've stated and once as VELKOB, all in the footprint column. Like I said, it's not causing me any problems, but was a big question mark that was bugging me. Especially why it would be in the footprint column and not in the description?

I've seen a lot of unique, non-standard, abbreviations and such when working with foreign documents, so I'm wondering if it's something like that.

I wonder if the "V" means "+" and the "D" means "-". Electrolytic capacitors would be polarized, and footprint should therefore include the polarization. Maybe?

Kudos to benta for pulling ELKO out of VELKOD.

I think VE1BILL got it. Each of the caps with VELKOD in the BOM have the positive side marked on the boards.

Thanks to benta and VE1BILL for their collective help!

I don't know for certain if these can be tied together, but I did run across the following:

On the second page of the above link, half way down the page, the author mentions substituting case B size capacitors with either size V or size D. Size D shares the same footprint size with the one that you indicated.

http://en.wikipedia.org/wiki/Surface-mount_technology

A bit over half way down the page on this link is a listing of Tantalum capacitor case sizes. Size V and D differ by only one dimension, and size D seems to be one size larger than size V.

Perhaps VELKOD is their way of saying it is a tantalum electrolytic capacitor, and that it will fit either size D or V footprints.
