STD-CTZ-1-19.2M

Crystal Units NX2016SF For Mobile Communications ■ 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.
