I recently learnt about the existence of PTC fuses, and I'd like to use one for an USB power supply I'm building. I guess there are PTC fuses on the PC side, but you never know.
I went happily to buy some at my local electronic supply store, but unfortunately they said they don't have resettable fuses (weird, they've got almost anything.) Since I'm spanish I didn't ask for PTC fuses, but asked for resettable fuses and explained how they worked, in case they're called something else here at Spain. They didn't have the fuses or knew where I could find them.
I've read PTC fuses are essentially thermistors, is it possible that they know them as thermistor or some other name, instead of resettable fuse?
