These look like MELF resistors, presumably of a fusible/flameproof metal film type.  They're not the easiest to find (through-hole is much more popular for them, and MELF also expands to Many End up Lying on the Floor -- it's a cylindrical package if you haven't already noticed, so it likes to roll away when you're trying to handle it. ;).  I'd try the major catalog distributors in your area -- they'll at least know what a MELF package is.  Power ratings for these, by the way, are on the same order as their through hole counterparts -- namely 1-2W.
