0.05 MHz THROUGH 10 MHz, HERMETIC SEAL, SQUARE WAVE, CMOS

This specification is approved for use by all Departments
and Agencies of the Department of Defense.

The requirements for acquiring the product described herein
shall consist of this specification sheet and MIL-PRF-55310

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.
