But if you 'touch' the sides of the Polyfuse
in any way, it takes heat out causing dissipation
requirements for transition to 'tripped' to go
up. Cool them off very much and they self-destruct
never transition and will self destruct.
You can't glue them down for vibration resistance.
I poked around on Digikey and found this new kid on
the PolySwitch block . . .

Seems to fit into the standard Mini-ATC fuse holder.
Only found the one size. Will carry 8A at 25C but
takes as much as 8 seconds at at 40A . . . REALLY
slow even for a 10A thermal breaker.
I've used these things in surface mount versions
to protect ECB traces at sub-amp trips . . . but I
don't see that they're yet ready for prime time in
power distribution.
