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
Exceeding the absolute maximum ratings may cause permanent damage. Exposure to absolute-
maximum-rated conditions for extended periods may affect device reliability.
