Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure the load capacitance and tolerance match the circuit design requirements. Confirm that the TA temperature range (-40°C to +85°C) aligns with the operational environment. Check for RoHS compliance status if required by project specifications.

Crystals Selection Notes

Select this component when a hermetically sealed package is necessary for long-term stability in varying environments. Ensure the system oscillator circuit can accommodate the 9 pF load capacitance. Consider the ±100 ppm tolerance limit for wide-temperature accuracy requirements compared to tighter tolerance options.

Crystals Part Context

This part belongs to the CM8V-T1A series of ultra-miniature tuning fork crystals. The series is characterized by its small footprint and robust construction, designed specifically for applications where size and reliability are critical constraints.

Crystals Replacement Considerations

Direct substitutes include other CM8V-T1A variants with different load capacitances or tolerances, such as those with 7pF or 12.5pF loads, provided the electrical parameters fit the application.
