Effective January 1, 2008

The SM11xxB series is discontinued.

This has been discontinued because:

•

the difficulty of the older design to assemble well in the newer RoHS compliant high

temperature reflow processes.

the cover assembly was not meeting some of the cleaning and assembly needs of the newer

processes.

the components needed to make these parts are no longer available.

This requirement is best met by using an SM77xxD 5x7mm SMD oscillator.
