It is common to find NTC thermistors packaged in the form of a Bulk. In order to make it more convenient, it has been included in the package Bead. NTC thermistors require a resistance tolerance of ±20% for them to function. Ensure that the temperature of NTC thermistors is set to -40°C~250°C in order to ensure reliable performance. NTC thermistors are designed to operate reliably at temperatures below 250°C. In order to preserve reliability, NTC thermistors should not be operated at temperatures below -40°C.
