Keeping PTC thermistors in SMD/SMT packages prevents them from being damaged. Packaged in the Cut Tape for safety, these PTC thermistors are designed to perform at high temperatures. Ensure that the PTC thermistors are set to -40°C as their minimum operating temperature. In order for this thermistor to work properly, the operating temperature must not exceed 85°C. PTC thermistors have terminations of 2. When operating, PTC thermistors could deliver a voltage of 60V. The DC circuit uses thermistors with a 60V voltage rating.
