I think, aluminium electrolytics are meant, as these have a lot of "wear" and can die. Hence, you can use tantal or niob electrolytics, which have a dry eletrolyt. Or you can use ceramics which are already available at 100uF. Attila Kinali -- Why does it take years to find the answers to the questions one should have asked long ago?

Like a CPLD/FPGA the PIC has the advantage of being fully synchronous and all on one die. /tvb [1] http://leapsecond.com/pic/ [2] https://www.tapr.org/kits_t2-mini.html

On mine the duty cycle is off by around 1.25% ------------------- > They all will eventually die as the las of the VFD displays wear out. At that point, hopefully we all will be running them via serial or GPIB and not even notice the issue.

On the LTC1000A, Linear notes that the unit has a different die, and they recommend running the LTZ1000A 10 degrees higher than the plain LTZ1000. Has anybody computed the values of the resistors to run the LTZ1000A at 50C ?

http://www.nytimes.com/interactive/science/a-century-of-cicadas.html A Century of Cicadas Periodical cicadas live underground for 17 or 13 years before emerging to sing, mate and die. This year’s cicadas are Brood II, one of 15 surviving regional broods.

You may not die from it buy it is crippling . He told me he got while fishing for stripers down by the shore . And he could no longer walk ...not sure if he was ever able to again since the person I knew who was in the same rehab was discharged before he was . .wasn't sure if everyone knew just how serious that virus is . He told me it attacks your brain .  

I hope the mouse didn’t die from any kind of poison.  The mouse could’ve gone out and bled to death and  then it would have been bad for the Blue jay. Susanne Shrader
