A great guide from AVX on output capacitor types and their specific uses based on ESR, ESL and temperature properties. Link here (PDF)

This document discusses the effect of capacitors on output power quality. It evaluates and provides a comparison of different capacitor technologies, their high reliability qualification availability from COTS+ to space level, and their impact on the output filtering capabilities in switching power supplies primarily used for mission critical applications.

  • Pekka Akselin: This is ridiculous!? :-) We are back at 256(!) byte EPROMs that needed multiple, a handful, of voltages to run! :-(
  • KH: Let's try a back-of-envelope calc balancing energies. From MCP1700 datasheet, there are graphs for a 200mA load step. Estimate the energy shortfall as 12uJ. Say...
  • Daniel: It's been a week and my comment is still awaiting moderation. Apparently the CIA doesn't want their involvement known?
  • KH: Agree, so okay, I guess he must have learned from somewhere. 100nF and 1000uF is so far apart, that was jarring; it's more magic incantation...
  • Max: I have a suspicion the hefty electrolytic cap might be some sort of cargo cult carry-over from other RF-based projects - for instance, I've seen...
