3 Description

The TMP61-Q1 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 and a 2-pin,

through-hole, mini-sized transistor-outline TO-92S

package.
