Does anyone know a good source for relatively small peltier thermoelectric units, something in the order of 15x15 to 25x25 mm?
I want some affordable ones that are consistent with eachother for LPM purposes, preferably widely available to make a project that can be reproduced by others.
Most i find are actually larger than required, which in this case is not a good thing since thermal mass should be as low as it can be within reason. I'm not looking for specialized units, just small versions of the regularly available ones for chip cooling etc.
If someone sells them i'll be happy to hear it, but links to useful items on ebay or ali are also very welcome.
