Consult factory for available frequencies and specs. Not all options available for all frequencies. A special part number may be assigned.
Frequency Stability is inclusive of frequency shifts due to calibration, temperature, supply voltage, shock, vibration and load
Due to part size and factory abilities, part marking may vary from lot to lot and may contain our part number or an internal code.
