>Anyone know if any vendors make inexpensive ceramic resonators in the -40 to >+85 deg C operating temperature range (that are suitable for PICs)? > >Thanks, Murata seem to rate their CSA/CSB (and other) ceramic resonator series at -20C to +80C. +/- 0.5% initial tolerance. +/- 0.3% across temperature +/- 0.3% aging They have an informative 17 page PDF file available. www.murata.com/develop/inde.htm for starters. They are fairly helpful (I'm told" and may well be able to comment on the -40 to -20 C performance. regards Russell McMahon _____________________________ >From another world - www.easttimor.com What can one man* do?
