Supercapacitor with more user-friendly voltage

These look interesting...

These would work for 3.3v supplies...clocks, usb chip, SATA chip...lots of possibilities

think i got some if them not tested yet
There lithium i believe with a min voltage requirement
Kinda like capatteries

Dang, I'm always in your wake ;-)

Quality safety instructions, heh...

Yeah, 2.2v...slightly apprehensive to connect them to anything! Might try it on the USB card...limited downside potential ;-)

Does anybody know a typical application of these boys?

Well, I'll probably run some tests before I actually connect it to something that matters but my hope is that Nigel's USB card recipe (elsewhere on here) needs a battery supply of 3.3v. I was thinking about sticking one in parallel with the power supply at the card end.

...or any of the 3.3v oscillators that I've replaced on the motherboards, SATA cards, perhaps even the clock board on Ian Canada's FIFO circuit.

Basically my thinking is that they'll act as an output capacitor that is very localised to the load.

Anyone else got any thoughts?

Yea worth a try
I never found much or any difference with the the lenght of wire between the batteries and the device

In fact i often find caps a bottleneck

Trying on an oscillator sounds like a good test
