Crystals Procurement Notes

Verify the specific suffix codes against official Suntsu documentation to confirm exact electrical tolerances and temperature ratings. Ensure the procurement channel provides valid manufacturer traceability. Confirm that the 4-SMD package variant matches the required PCB land pattern specifications before finalizing orders.

Crystals Selection Notes

Select this component when a 12.288 MHz reference is required in a compact 2520 form factor. The 120 Ohm ESR value dictates specific circuit loading requirements. Verify that the -20°C to +70°C operating range aligns with the target application environment, as industrial variants may offer wider thermal coverage.

Crystals Part Context

This part belongs to the SXT224 series of ceramic surface-mount crystals from Suntsu Electronics. The series is characterized by its small 2520 package size and four-pad configuration, designed to minimize electromagnetic interference compared to two-pin alternatives while maintaining high frequency stability for digital clocking applications.

Crystals Replacement Considerations

Direct substitutes must match the 12.288 MHz frequency, 20pF load capacitance, and 4-SMD package dimensions. Cross-reference ESR values and temperature ranges to ensure functional compatibility within the existing circuit design constraints.
