Product Description

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

Characteristics:

Humidity measuring range: 1- 99%RH
Supply voltage: 10V
Nominal capacitance: 177-183PF, (typical 180PF)
Averaged sensitivity from 33% to 75%, 0.31PF/% RH
Time constant (33 to 80%RH, still air at 63% T: 3s, (maximum 5s)

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
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
