TE Circuit Protections designs Polymeric Positive Temperature Coefficient Devices. PolySwitch PPTC devices are designed to protect electronic systems and gadgets which are prone to both system ...

We investigated the effects of cooling rate after polymer melting on the room temperature resistivity (ρ L) and on the positive temperature coefficient (PTC) effect of resistivity of high-density ...

Said to be ideal for low-voltage DC and AC applications, and especially high-current apps, these positive temperature coefficient (PTC) thermistors boast of a compact design, flexible construction, ...

[abizar] lucked into some aluminum blocks, one of which had test-tube-sized holes in it–just the thing to turn into a dry bath for his biology projects. He stuck a 100W positive temperature ...
