There is a package of a Bulk in which NTC thermistors can be found. We have included it in the Ring Lug package for your convenience. As a result, NTC thermistors must have a resistance tolerance of ±5% in order to function correctly. NTC thermistors should be set to -40°C~150°C temperature in order to provide reliable performance. In the NTC thermometers, 20mW is the maximum power setting.
