Crystals Procurement Notes

Verify the specific package dimensions and pin configuration against the official datasheet before PCB layout finalization. Confirm that the load capacitance requirements of the target circuit match the 8 pF specification to ensure accurate frequency performance. Check for any specific handling instructions regarding electrostatic discharge protection during assembly.

Crystals Selection Notes

Select this component when a 40 MHz reference clock is required for applications needing ±30 ppm stability. Ensure the design accommodates the 4-SMD no-lead form factor. Consider the 100 Ohm ESR value for oscillator circuit compatibility. Verify that the -40°C to +85°C temperature range meets the environmental constraints of the end application.

Crystals Part Context

This part belongs to the SXT1148BB27 series of surface-mount crystals from Suntsu Electronics. The series offers various frequency options while maintaining consistent electrical characteristics such as load capacitance and stability. It serves as a critical timing element in compact electronic designs requiring reliable frequency generation.

Crystals Replacement Considerations

Direct substitutes must match the 40 MHz frequency, 8 pF load capacitance, 100 Ohm ESR, and 4-SMD no-lead package. Verify that alternative components offer identical ±30 ppm stability and operate within the same -40°C to +85°C temperature range to maintain system timing integrity.
