2.1 Absolute Maximum Ratings
CAUTION: The absolute maximum ratings are stress ratings only. Stresses greater than those listed below can cause permanent damage to the device. Functional operation of the HS410x at absolute maximum ratings is not implied. Exposure to absolute maximum rating conditions might affect device reliability. Parameter Conditions Minimum Maximum Unit Storage Temperature Range Recommended 0 to 60°C -40 125 °C
2.2 Recommended Operating Conditions
Important note: The HS410x series sensors are optimized to perform best in the more common temperature and humidity ranges of 10°C to 50°C and 20% RH to 80% RH, respectively. If operated outside of these conditions for extended periods, especially at high humidity levels, the sensors may exhibit an offset. In most cases, this offset is temporary and will gradually disappear once the sensor is returned to normal temperature and humidity conditions. The amount of the shift and the duration of the offset vary depending on the duration of exposure and the severity of the relative humidity and temperature conditions.[1] The time needed for the offset to disappear can also be decreased by using the procedures described in sections 9 and 10.

This section discusses soldering considerations for the HS410x. clean’ solder paste to avoid the need to wash the PCB. involved in the soldering process to avoid irreversibly damaging the sensor element. The recommended soldering profile for a lead-free (RoHS-compliant) process is shown below. Figure 15. Recommended Soldering Profile component with a higher thermal mass means the temperature at the small sensor will be higher than expected. For manual soldering, the contact time must be limited to 5 seconds with a maximum iron temperature of 350°C. strongly recommended that a “no-clean” solder paste is used to avoid the need to wash the PCB. in the relative humidity readings, which will slowly disappear as the sensor get exposed to ambient conditions. ■ A relative humidity of 75% RH at room temperature for at least 12 hours. ■ A relative humidity of 40% to 50% RH at room temperature for 3 to 5 days.
