xEy is some kind of semi-standard notation for resistor values
in the first three decades, when people do not want to write R
(as it might be confused with the part number) or a dot (which
might get lost when printing). But I don't know where this notation
came from, or what the E stands for. I can only say I have seen it
quite a few times already.
