• Communication equipment frequency references

Crystals Procurement Notes

Verify the specific suffix DC484 against official Suntsu documentation to confirm exact electrical parameters and package dimensions. Ensure compatibility with existing PCB footprints designed for HC-49/US style surface mount components. Cross-reference datasheet revisions to validate current manufacturing status and compliance certifications before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 12 MHz reference signal is required within an industrial temperature environment. The ±20 ppm tolerance suits applications needing precise synchronization without the cost of higher-grade oscillators. Consider the 18 pF load capacitance requirement to ensure circuit resonance matches the crystal specifications for optimal performance.

Crystals Part Context

This part belongs to the SXTHM series of surface-mount crystals from Suntsu Electronics. The series offers various frequencies and packages tailored for compact electronic designs. The SXTHM218DC484 variant specifically targets applications demanding reliability in harsh thermal conditions while maintaining a small profile suitable for modern printed circuit board layouts.

Crystals Replacement Considerations

Direct substitutes include other 12 MHz surface-mount crystals with identical 18 pF load capacitance and HC-49/US footprint. Verify that alternative parts meet the same ±25 ppm stability and -40°C to +85°C temperature range requirements to maintain system timing integrity.
