HTS2030SMD Datasheet, PDF (1/4 Pages) List of Unclassifed Manufacturers – Temperature and Relative Humidity Sensor

TECHNICAL ₁ DATA
TEMPERATURE AND RELATIVE HUMIDITY SENSOR HTS2030SMD
Meets RoHS regulations
Based on a unique capacitive cell for humidity measurement and a Negative
Temperature Coefficient (NTC) thermistor for temperature measurement, this dual purpose
relative humidity / temperature miniaturized sensor is designed for high volume, cost
sensitive applications with tight space constraints. It is useful in all applications where
dew point, absolute humidity measurements or humidity compensation are required.
MAIN FEATURES
● Miniature Surface mount SMD package.
● Lead free components.
● Full interchangeability with no calibration required in standard conditions.
● Instantaneous desaturation after long periods in saturation phase.
● Compatible with automatized assembly processes, including Pb free
wave soldering and reflow processes (1)
● High reliability and long term stability.
● Patented solid polymer structure.
● Suitable for linear voltage or frequency output circuitry.
● Fast response time and very low temperature coefficient.
● Part may be washed with distilled water.
● Individual marking for compliance to stringent traceability requirements.
