DESCRIPTION

· The TMP61 is a silicon-based linear thermistor with a positive temperature coefficient (PTC).
· It offers linear resistance change across temperature with a nominal resistance of 10 kΩ at 25°C.
· The device operates over a wide temperature range from -40°C to +150°C.
· It features consistent sensitivity with a TCR of 6400 ppm/°C at 25°C and a typical TCR tolerance of 0.2% across the temperature range.
· The TMP61 has a fast thermal response time of 0.6 s and is designed for long-term reliability with a typical long-term sensor drift of 0.5%.
· It is available in 0402 X1SON, 0603 SOT-5X3, and 2-pin through-hole TO-92S packages.
