Crystals Procurement Notes

Verify the specific suffix DC48 against official Suntsu Electronics documentation to confirm package dimensions and termination style. Ensure the operating environment remains within the specified commercial temperature range to maintain the stated ±20 ppm stability. Cross-reference the 18 pF load capacitance requirement with the target circuit design to prevent frequency deviation during operation.

Crystals Selection Notes

Select this component when a 12.288 MHz reference signal is required for digital systems. The 4-SMD no-lead package offers space efficiency compared to through-hole alternatives. Consider the ±20 ppm tolerance relative to system jitter requirements. Verify that the 100 Ohm ESR matches the oscillator circuit's drive level specifications to ensure reliable startup and sustained oscillation.

Crystals Part Context

This part belongs to the SXT32418 series of surface-mount crystals from Suntsu Electronics. The series provides various frequency options optimized for consumer electronics and industrial applications. The SXT32418DC48 variant specifically denotes the package type and terminal configuration, distinguishing it from other mechanical forms within the broader product line.

Crystals Replacement Considerations

Direct substitutes must match the 12.288 MHz frequency, 18 pF load capacitance, and 4-SMD no-lead package dimensions. Verify that alternative components meet or exceed the ±20 ppm stability and 100 Ohm ESR specifications. Check RoHS compliance status to ensure regulatory alignment.
