Interchangeable and Point Matched

Interchangeable and Point Matched Icon_RedArrow_Down

Features:

mini_rtd

Interchangeable thermistors have tight tolerances guaranteed to track a specific resistance temperature (R/T) curve over a temperature range. Point Matched thermistors are tested at a given temperature and guaranteed to be within a specified percentage of the nominal resistance at that temperature.
