I need a component to heat a box up to 80°C. Any recommendations?
I don't have a specific part to recommend. However, I'd look at something qualified for automotive or industrial as they are specified to operate up to 105°C or 125°C. Consumer parts are only good to 85°C, so you may find they burn out. Best thing is to try a few and see what works. Also be aware of thermal runaway - if I remember correctly, as the device heats up, its resistance drop, causing more current to flow, which causes the resistance to drop further, resulting in more current flow...
Good luck!
