The TMP61-Q1 series of small silicon linear thermistors aredesigned for temperature measurement, protection, compensation, and control systems. Compared totraditional NTC thermistors, the TMP61-Q1 device offers enhancedlinearity and consistent sensitivity across the full temperature range. The TMP61-Q1 offers robust performance due to device immunity to environmentalvariation and built-in fail-safe behaviors at high temperatures. This device is currently availablein a 2-pin, surface-mount, 0402 footprint-compatible X1SON package.
