TI's humidity sensors are shipped in sealed anti-static tape and reel cavities. The sensors can be stored in a humidity and temperature-controlled environment after being removed from the tape and reel cavity prior to assembly. Storage temperature and humidity limitations are defined by the moisture sensitivity level (MSL) of the sensor. Refer to the application note MSL Ratings and Reflow Profiles for more details.
Do not store the humidity sensors within anti-static polyethylene bags or packing materials (pink foam/wrap), as these materials emit gases that can affect the sensor. TI recommends metallized, anti-static sealable bags for storage. Do not use adhesives or tape inside the storage container as outgassing can degrade the polymer as well.
