Hi Folks,

Sorry for this off-topic post but I've run out of ideas.  Does anybody
know where I can get 10 to 20 pieces of a 12MHz SMD crystal with Cload
of less than 16pF, ESR less than 100 ohms and a frequency tolerance of
better than +/- 60 ppm?  Digi-key has one (#644-1018-1-ND) but it is a
bit big at 8 x 4mm.  Digi-key #644-1034-1-ND is a better size at 4.9 x
3.1mm but it's ESR is 120 ohms.

So, any ideas?

Thanks,

Richard Cooke

Yes - it looks like they carry Abracon and their Cload is 18pF which
is a bit too high.

I'd go direct to the manufacturers, they tend to have other stuff that
DK dosen't carry.
BTDT, and it had to be <0.8mm thick.

Tried Mouser?
