I'm hoping to use 0201 caps and resistors in a new design but so far have only found one company who makes such small devices (Murato). Can anyone direct me to any other supplier? Are there any particular problems associated with using such small

Steve: Try to find something that�s common to all your skewed parts. We haven�t had much trouble with it except for some MELF diodes a couple of years ago which didn�t look well aligned but made no trouble with specs. Better suited pad design solved
