Crystals Procurement Notes

Verify the specific suffix codes against official Suntsu documentation to confirm exact tolerance and temperature specifications. Ensure compatibility with PCB footprint requirements for the 4-SMD no-lead package. Cross-reference datasheet revisions to validate current manufacturing status and compliance certifications before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 48 MHz reference is required with ±20ppm initial accuracy. Consider the -10°C to +60°C operating range for industrial applications. Evaluate the 8pF load capacitance requirement against circuit design constraints. Compare ESR values with driver capabilities to ensure reliable oscillation start-up conditions.

Crystals Part Context

This part belongs to the SXT1148 series of surface-mount crystals. Variants in this family differ primarily in frequency, tolerance, and temperature ranges. The DC48 suffix indicates specific electrical characteristics distinct from other series members like the CC07 or EC48 variants.

Crystals Replacement Considerations

Direct substitutes must match the 48 MHz frequency, 8pF load capacitance, and 4-SMD package dimensions. Verify that alternative components meet the same ±20ppm tolerance and 100 Ohm ESR specifications. Check thermal performance alignment with the -10°C to +60°C operational window.
