I would like to know which standard that is, that you are referring to. Most
reels of components that I have seen, the polarity is on the left at zero
rotation.  On a related topic, IC's in sticks have pin 1 to the upper left,
and IC's on reels have pin 1 lower left, everything I have seen is always on
the left, or have I lost my mind? (don't have any reels here)

Onward thru the fog,    Jack

components?

        Hi Paul,

        According to the Jedec standard:
        The component should be drawn parallel to the X axis
        The polarisation marking and Pin 1 to the right.

        Cheers,

        Barry Olney
