low ESR 100uF tantalums can be pretty expensive, and when i saw that in the hardware guide, i blew it off and just used some 100uF lead electrolytic. I couldn’t find the tantalums over a few uF locally anyway. I even got a 2200uF lead electrolytic monster just to be sure.
The telit had problems during start up with both types. Didn’t work with that type of cap. period. Looks like you threw 7000uF at it. I dont really have room for that.
I broke down, ordered some 100uF low ESR tantalums online, put it in the circuit – unit works perfectly and has never had any power problems. :roll:
I put 100uF low ESR tantalums in all my designs.
