Platinum temperature sensors are IST's flagship products, featuring the highest performance and the widest application range.
The document describes IST's high‑purity platinum and nickel thin‑film temperature sensors designed for SMD 0805 and 1206 packages. It outlines the sensor construction, typical features such as short response time, small dimensions, and long‑term stability, and explains the manufacturing process that enables mass‑production with high accuracy.
Technical data include nominal resistances, temperature ranges, temperature coefficients, response times in water and air, self‑heating characteristics, and detailed mechanical dimensions. Ordering information, tolerance classes, and recommended measurement currents are also provided for designers and engineers.
| Nominal resistance | 100 Ω, 500 Ω or 1000 Ω |
|---|---|
| Temperature range | -50°C to +150°C (1P, 2P); -50°C to +250°C (3P, 4P) |
| Platinum TCR | 3850 ppm/K |
| Long‑term stability drift (Pt) | 0.04% after 1000 h at 130°C |
| Response time in water (1206) | 0.25 s (T0.63) |
| Package dimensions (0805) | 2.0 × 1.2 mm |
| Recommended measurement current (100 Ω) | typ. 1 mA max. |
The recommended measurement current for a 100 Ω sensor is typically 1 mA maximum.
In water, the 1206 sensor reaches 63 % of the temperature change in about 0.25 seconds.
The platinum sensor has a temperature coefficient of 3850 ppm/K.
