IST SMD 0805 + 1206 Platinum Nickel Thin-Film Chip Sensor Datasheet
The SMD 0805 + 1206 thin‑film chip sensor from IST is a platinum or nickel temperature sensor designed for high‑volume, automated production lines. It combines the accuracy and stability of Pt/Ni elements with cost‑effective, lead‑free construction suitable for pick‑and‑place assembly.
Key data include temperature ranges of –50 °C to +150 °C (1‑P, 2‑P) and –50 °C to +250 °C (3‑P, 4‑P), TCR values of 3850 ppm/K (Pt) and 6180 ppm/K (Ni), and compact package dimensions of 2.0 × 1.2 mm (0805) and 3.2 × 1.6 mm (1206). The sheet also lists soldering limits, contact options, response times, self‑heating, and long‑term drift specifications.
