T5321 Series
T5421 Series
5x7 mm Surface Mount High Reliability
Tristate/Non-Tristate, 1MHz to 100MHz
Features
RoHS Status
Leadless chip carrier package is hermetically
sealed for superior aging and field performance
Crystal angle controlled to ±1 minute for excellent
temperature stability
168 hour Class B burn-in and extensive
environmental testing for best performance in
rugged field environments
Start-up time <10 ms, typical
Tristate option available
Calculated MTBF is 3.8 x 106 hours at 125°C
Application
Surface Mounted PCB projects requiring high
reliability HCMOS clock waveforms
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
5x7mm SMD package has a hermetic seal, thus ensuring the integrity of the part. 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.
