MLX90247 Datasheet, PDF (4/11 Pages) List of Unclassifed Manufacturers – Discrete Infrared Thermopile Detectors

3. Glossary of Terms
IR : Infrared. Every object emits infrared
radiation in relation to its temperature. This
effect can be used to measure the temperature
without the need for physical contact.
NTC : See Thermistor
PTC : See Thermistor
Thermistor : Temperature dependant resistor.
Basically there are 2 types. The types that
increase their resistance with rising temperature
are PTC ( positive thermal coefficient ) types.
The ones that decrease their resistance with
rising temperature we call NTC ( negative
thermal coefficient ) types.
4. Absolute Maximum Ratings
Operating Temperature Range
Operating Temperature Range
Soldering Temperature
-20 ~ 85 °C
-40 ~ 150 °C
< 220 °C
T < 5 sec.
Exceeding the absolute maximum ratings may cause permanent damage. Exposure to absolute-
maximum-rated conditions for extended periods may affect device reliability.
