Crystal Units
NX2016SF
For Automotive
Features
■
Crystal Unit with built-in Thermistor construction for automotive.
● Placing temperature sensor(Thermistor) close to Crystal blank in one airtight
housing can detect more precise crystal blank temperature. Improvement on
frequency temperature compensation compared to present Crystal unit.
● It is ideal for applications such as vehicle communication equipment and car
navigation systems.
● Meets the requirements for re-flow profiling using lead-free solder.
● Conforms to AEC-Q200.
