If they're just resistors, Resqueline's advice is the best idea.
I'll mention that when I get stuck for SMD markings, some guy in France spends a lot
of time finding manufacturer's markings/identification.
I Google: matthieu benoit, and whatever cross reference I'm looking for, to see if he posted
it online.
Last list I checked had a complete listing for Philips SMD marking codes.
Might help, might not, but something to check.
