Ron Yeah mostly chip resistors have numbers using standard conventions, except Rohm/Eurohm who can have a really funky system, don't expect 102 to be 1K from some of these guys. But MLC caps 1206 (3.2 x 1.6mm) and below are rarely marked, but depends on manufacturer, 0805 (2.0 x 1.25mm) have never had markings as far as I recall. These I would view as big passive parts, excluding chip electrolytic/tantalums. Was that your definition of small?, normally we use 0603 (1.6 x 0.8mm) or 0402 (1 x 0.5mm) every day. No metric comments please ;-), its an affliction but I am used to it.
