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 TFLD646E is offered
in a surface mount package for
automated assembly.
