Mechanical (obsolete version):
The cover is no longer being supplied over this part. This part is made with a hermetically sealed
PE99xxDV series oscillator. This part is now exposed.
The cover has been deleted, the cover was causing problems with the newer high temperature RoHS lead
free processes. The cover purpose was only cosmetic.
All parts with 2008 date codes will be made in the new fashion.
There is no change in electrical properties.
Pletronics does recommend that all designs should transition to the PE99xxDV ceramic part.

The package is not hermetically sealed.
The sides are intentionally left open to permit cleaning material to freely flow in the package, thus
minimizing the accumulation of contaminants during cleaning processes.
The internal part of the package must be thoroughly dry before operating.
