NOTES:
1. Dimensions are in inches.
2. Metric equivalents are given for general information only.
3. Standard marking, except omit Part or Identifying Number (PIN) this location.
4. Unless otherwise specified, tolerances are ±.005 (0.13 mm) for three place decimals and ±.02 (0.5 mm) for two
place decimals.
5. Case to be connected to base pin 4 to permit shielding of the oscillator.
6. All pins with NC function may be connected internally and are not to be used as external tie points or
connections.
7. Pin numbers shown on package are for reference only and need not appear on part.

1/ For the purpose of transitioning this device to
MIL-PRF-55310,
‘Frequency stability versus temperature’ has been
renamed ‘Frequency-temperature tolerance’. The verification requirements of ‘initial frequency-temperature
accuracy (one-half temperature cycle)’ shall apply except that frequency measurements shall be referenced to
the frequency measured at +23C
1C
(f
ref
) instead of to the nominal frequency (f
nom
).
