grounded metal cover.
PROCESS RECOMMENDATIONS
TABLE 6.0
Solder Reflow
The component solder used internal to this device has a mel ting point of
221
°C. The peak temperature inside the device should be less than or equal
to 220
°C for a maximum of 10 seconds
Wash
Ultrasonic cleaning is not recommended
Notes:
1) Initial calibration @ 25
°C, Vc=2.18 Vdc.
2) Frequency vs. temperature stability
3) At the time of shipment after48 hours of operation.
4) Inclusive of calibration, operating temperature range, supply voltage change, load change, shock
and vibration, 20 years aging, Vc=2.18 Vdc.
5) Measured @ 25
°C, within 5 minutes, the unit will be within +/-0.1ppm of its reference frequency,
measured after 30 minutes of continuous operation at a stable 25
°C
6) Referenced to Fo @ 25°C, Positive Transfer Characteristic
