FSP 5VSB Question

Re: FSP 5VSB Question

999999999, as an observer of this debate I can say that your explanations have been arbitrary so far while PCBONEZ has put some science behind his...

Also, I see no reason for your bigoted attack on religion and what role it has to play in this thread.

^ Nonsense. If you don't understand something I suppose it does seem arbitrary but to suggest that science implies lowering ESR increases heat is madness.

I'm not attacking religion but "something" has to account for such a backwards view when it is most certainly NOT science. I get it though, you were predisposed to believe whatever PCBONEZ wrote was correct and will defend that even in spite of a clear equation and quotes by experts.

No, you're just being close-minded...

What do you think would be more wise of me as a not-so-technically inclined individual... I see one scientist offering a theory (albeit unpopular) but offering his reasoning behind his theory, and I have one who says "believe what I say because everyone else says it, and look, here's my proof of them saying it", who would I be inclined to believe?

The problem is that you underestimate the critical-thinking ability of human beings and expect them to believe what they're told. And, you have not succeeded in making a good argument for your point, which leads me to believe that you are wrong.

By the way, deeply RELIGIOUS Jews get awarded Nobel Prizes in Israel in the field of science... What do you have to say to that?

Re: FSP 5VSB Question

^ let's stick to science instead of drifting further off topic? I'm not interested in "what you believe" nor do facts depend on whether you accept them. Science does not depend on the beliefs of individuals. Earlier I posted a clear scenario, a reproducible test which anyone can do to establish on their own whether lower ESR increases self heating. Science requires this reproducibility. Take a switching power supply circuit, like the VRM section of a motherboard, and swap a cap with one same physical size but having half the ESR. Put enough of a load on it to cause temperature rise. Measure temperature before and after.

The cap with half the ESR stays cooler which supports what I wrote, not having twice the thermal rise over ambient temperature which would support what PCBONEZ wrote. Note that you can't just swap a single capacitor and leave the others unchanged in the same subsection of the circuit as you then have another variable involved with the mismatch in ESR among the sample group since the circuit I described typically places more than one capacitor in parallel electrically. You can remove that variable by simply using a different switching power supply like a wall wart, AC-DC power brick, etc. which has only one capacitor instead of multiple in parallel, though I mentioned a motherboard because it is easier to increase load on one using software to increase CPU utilization.

Science requires following a scientific method, not automatically supporting whatever a particular source has to say or write which is trust, not science. Do the test. The capacitor industry has for decades. [unsubscribed from topic, bye]

But this is not a VRM! This is the puny pi filter of the 5VSB circuit of a PSU which consists only of one filter input and output cap...
