Hi Tom, Not sure if Pb-free is the only change. We received feedback from someone that is evaluating the Fury GPSDO to replace the EOL Thunderbolt GPSDO in their application. They looked at the T-Bolt, T-Bolt-E, Mini-T, and Fury (the single oven, AT-cut, low-cost version - the double-oven Fury option would have performed better). Here are some abbreviated comments: With the announcement of the end of life for the Thunderbolt we have evaluated the Thunderbolt E, the Mini-T and now the Jackson Labs Technologies Fury as candidate replacements. Unfortunately none of them look to be suitable although there is an indication that the Fury is not far off... It appears that when both the Fury and the Thunderbolt E are at their best they are on a par with the Thunderbolt... They compared Phase Noise performance as well as stability. If the Thunderbolt-E is really just a Pb free version, then it may be unit-to-unit tolerance that is making the E perform worse than the original reference unit. Or Trimble may have resorted to a lesser OCXO to save cost and meet RoHS requirements. BTW, I wonder how the RoHS high-temp soldering requirements affect OCXO's, since the soldering temp now has to be significantly higher (to the point where non RoHS connectors can actually melt for example). In my opinion this can have significant negative impact on the Crystal etc, besides all the long-term reliability issues with Tin Whiskers.. bye, Said In a message dated 5/18/2008 20:46:33 Pacific Daylight Time, [EMAIL PROTECTED] writes:

It seems the newest ones (E suffix) are ROHS compliant. Other than the lead, I can't see a difference; does anyone know for sure? /tvb _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. **************Wondering what's for Dinner Tonight?
