CRYSTAL CONTROLLED OSCILLATORS
The Connor Winfield TFLD646E
is a Surface Mount Fixed
Frequency Temperature
Compensated Crystal Oscillator
(TCXO). Operating at 3.3Vdc, the
TFLD646E will maintain 4.6ppm
frequency tolerance for 20 years
over the Industrial Temperature
Range. The TFFD646E is offered
in a surface mount package for
automated assembly.

PROCESS RECOMMENDATIONS
TABLE 7.0
Solder Reflow
The component solder used internal to this device has a melting 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.
Note:
1) Inclusive of calibration, frequency vs. t emperature stability, supply voltage c hange, load
change, shock and vibration, 20 years ag ing.
