Description
These high reliability oscillators provide HCMOS
clock waveforms for applications subjected to the
most stringent environmental conditions. They are
mechanically robust and weigh less than 0.2 grams.
This 5X7 mm SMD package has a hermetic seal,
thus ensuring the integrity of each oscillator. Each
oscillator is burned-in at 125°C for 168 hours,
temperature cycled and centrifuged then fully
tested in accordance with Table 1. Reliability tests
are performed per Table 2. The calculated MTBF is
3.8X10
6
at 125°C.
Typical Applications
Surface Mounted PCB projects requiring high reliability
