SMD PTCs as Thermal Switches

The TPM series of SMD PTC thermistors are frequently used as thermal switches in electronic circuits. Their small size (0402, 0603 or 0805) and steep RT curve (at the trip point) makes these solid-state temperature switches ideal for small spaces and they are also very simple to incorporate.
