Yep, that was me looking for the same part. Does yours look like this?
According to Onecall Farnell 'a blue band at position 5 indicates 20%
tolerance' which would make it a tolerance multiplier of 2.
However the only ones they sell are 5% tolerance, ie brown-black-gold-gold
not brown-black-gold-silver + blue, but the technical chap I spoke to seemed
certain these would be ok. I bought 5 just in case.
Onecall are education-only suppliers but the same part numbers work with
Farnell/Element14. Part# is 1692450.
