[Boatanchors] Postage Stamp Mica Question

[J. Forster]

Hi,

I'm still working on the ART-4 transmitter and want to put values on the
schematic. The unit has about a half dozen 'postage stamp' mica caps.

They are all marked like 'Type 5' on thos page:

http://www.radioremembered.org/capcode.htm

and have 6 color dots.

Reading in the correct order, clockwise starting at the top left, the dots
are:

Black
Green
Brown
Black
Yellow
Red

See the issue? The value SEEMS to be 051 pF; 400 VDC, 2%

Question:  Was it ever convention to use a leading zero in color codes for
this type of cap? I've never seen it before.

Thanks,

-John
