Description

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