Max. Min. Max. Ambient Temperature -20 ºC +70 ºC -30 ºC +80ºC Humidity (without condensation) Note 4, 5 Note 4,6 Note 4: Background color changes slightly depending on ambient temperature. This phenomenon is reversible. Note 5: Ta ≤ 70ºC: 75 RH max; Ta > 70ºC: absolute humidity must be lower than the humidity of 75% RH at 70ºC. Note 6: Ta at -30ºC will be <48 hrs, at 80ºC will be < 120 hrs when humidity is higher than 75%. AND491GST3-3V-W-LED Intelligent Character Display
