Crystal Units
NX2016SF
■ Features
Crystal Unit with built-in Thermistor construction.
● Minimize circuit design space by combining crystal unit into one component.
(Presently, Crystal unit and temperature sensor is mounted in one board separately.)
● 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.
● Single cavity housing which is ideal to module applications.
● External configuration size is 2.0x1.6mm typ., H0.65 mm max.
● A surface-mount crystal oscillator. (Reflow soldering is possible.)
● Lead-free. Meets the requirements for re-flow profiling using lead-free solder.
