#104770 - I have never used any such amd never had Responding to: ???'s previous message |
only a parallel resistor can stop self resonations.I am not concerned into high current needs ,so i'll try to use series resistor since then.
I have never used any such amd never had a problem. I think ferrites and tantalums are lousy -- or is that lossy? -- enough that there should not be a problem. Anyhow, if needed a series resistor will improve the filtering, a parallel will reduce it. on another note, it puzzles me that there is Vcc (unregulated) and +5V which would be "my" Vcc. on a third note I would never put the filters before the regulator, only after, Erik |
