Ptc thermal fuse

WebA fuse is, of course, a last resort in case of a malfunction, so pick one that will blow at a temperature higher than your max anticipated operating temperature. The heater/PTC element is getting hotter than the temperature set-point of the system (26-28 deg C), so you wouldn't pick a thermal fuse that blows at like 40C. WebFor instance, these EPCOS switching PTCs are designed for 30,000 cycles. At a higher price point, clamped PTC ceramics have free contact motion when heating up, permitting between a quarter million and a million switching cycles. In contrast, these Bourne SMD PTCs are rated at a mere 100 cycles.
