TABLE 7.0
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 t han or
equal to 220°C for a maximum of 10 seconds
Ultrasonic cleaning is not recommended.
Note:
1) Inclusive of calibration, frequency vs. temperature stability, supply voltage change, load change,
shock and vibration, 20 years aging.
