Has anyone used/measured these? I bought a 140C one from digikey,
(The /F20A... is the part number.)
Sticking this on a hot plate in open air ~180C.. well the solder on heater resisors melted first. I stuck thermometers on the top... ~155 C... (I realized driving home that the plastic thermostat was in between the hot plate and the brass 4-40 bolt going to the thermometer on top... to-220 pac tip32. So now I'm heating the thermo stat from top and bottom. Maybe in an oil bath this would switch at 140 C... but it could be better....
Is there a thermostat with a better thermal tab?
