PROCESS RECOMMENDATIONS
TABLE 6.0
Solder Reflow
The component solder used internal to this device has a m elting 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
ORDERING INFORMATION

Ultrasonic cleaning is not recommended
BSOV3S3 - 12.80MHz
Notes:
1) Initial calibration @ 25°C, Vc=1.59 Vdc.
2) Frequency vs. temperature stability
3) At the time of shipment after48 hours of operation.

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
