Crystal Units
NX2520SG
â Features
Crystal Unit with built-in Thermistor construction.
â Minimize circuit design space by combining crystal unit into one component.
(Presently, Crystal unit and temperature sensor is mounted in one board separately.)
â 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.
â Single cavity housing which is ideal to module applications.
