VC-820_12 Datasheet, PDF (6/7 Pages) Vectron International, Inc – CMOS Crystal Oscillator

Stresses in excess of the absolute maximum ratings can permanently damage the device. Functional operation is not
implied at these or any other conditions in excess of conditions represented in the operational sections of this datasheet.
Exposure to absolute maximum ratings for extended periods may adversely affect device reliability. Permanent damage is
also possible if E/D is applied before V .

The VC-820 is qualified to meet the
JEDEC standard for Pb-Free assembly.
The temperatures and time intervals
listed are based on the Pb-Free small
body requirements. The VC-820 device
is hermetically sealed so an aqueous
wash is not an issue.
