The Connor-Winfield TFLD546 is
a Surface Mount Temperature
Compensated Crystal Oscillator
(TCXO). Operating at 3.3Vdc,
the TFLD546 will maintain
±4.6ppm frequency tolerance
over 20 years. The TFLD546 is
offered in a surface mount
package for automated

PROCESS RECOMMENDATIONS
Solder Reflow
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 than or
equal to 220°C for a maximum of 10 seconds
Wash
Ultrasonic cleaning is not recommended.
