Crystals Procurement Notes

Verify the specific suffix AG5 against official Epson documentation to confirm the 7.0 pF load capacitance and ±30 ppm tolerance parameters. Ensure the procurement channel provides valid RoHS3 compliance certificates. Cross-reference the part number with the manufacturer's current datasheet to confirm availability status, as this item may not be normally stocked. Confirm that the soldering profile matches the specifications for SMD crystals to prevent mechanical stress damage during assembly.

Crystals Selection Notes

Select this component when a 32.768 kHz reference is required with a ±30 ppm tolerance specification. The 7.0 pF load capacitance must match the oscillator circuit design requirements. Consider the 65 kOhm ESR value for drive level compatibility, typically limited to 1 uW. The operating temperature range of -40°C to +85°C suits standard commercial applications. Compare dimensions against PCB footprint constraints to ensure the 6.7x1.5 mm package fits the layout.
