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. ■ Specifications Model Item Nominal Frequency NX2016SF 19.2 to 52 MHz Overtone Order Fundamental Frequency Tolerance (25 ± 3°C ) ±10 × 10−6 Frequency versus Temperature Characteristics (with reference to +32 °C) ±12 × 10−6 Operating Temperature Range −30 to +85 °C Storage Temperature Range −40 to +85 °C Equivalent Series Resistance Refer to *1 Level of Drive 10 μW Load Capacitance 7 pF Specifications Number STD-CTZ-1 NTC Thermistor for Temperature Sensor Dimensions 0.6 × 0.3 × 0.15 mm Resistance [R25] 100k Ω ± 1 % B-Constant [B25-50] 4250K ± 1 % ■ Dimensions mm 2.0±0.1 #4 #3 Terminal land connections *1 Equivalent Series Resistance Nominal frequency (MHz) Equivalent Series Resistance max.
