PACKAGE CHARACTERISTICS
TABLE 5.0
Package
Surface Mount, Non-hermetic package consisting of an FR4 substrate with
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=1.48 Vdc.
2) Frequency vs. temperature stability, 0 to 70
C absolute.
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=1.48 Vdc.
5) Measured @ 25
C, within 5 minutes, the unit will be within +/-0.1ppm of its reference frequency,
measured after 30 minutes of continuo us operation at a stable 25
C
6) Referenced to Fo @ 25C, Positive Transfer Characteristic
