NX1210AC
For Mobile Communications
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 conguration size is 1.2x1.0mm typ., H0.55 mm max.
● A surface-mount crystal oscillator. (Reow soldering is possible.)
● Lead-free. Meets the requirements for re-ow proling using lead-free solder.
