Crystals Procurement Notes

Verify the specific suffix DD16 against official Suntsu documentation to confirm the exact temperature range and tolerance specifications. Ensure the ordering part number matches the required 37.4 MHz frequency and 12 pF load capacitance. Confirm that the SMD2520-4P package dimensions align with the target PCB footprint. Request the latest datasheet to validate RoHS compliance and material declarations before finalizing procurement.

Crystals Selection Notes

Select this component when a 37.4 MHz reference is required with moderate stability. The ±20 ppm tolerance suits applications not demanding high-precision industrial grades. The SMD2520-4P package offers space efficiency for dense layouts. Consider the -10°C to +60°C range suitability for the intended operational environment. Compare ESR requirements with the oscillator circuit design to ensure proper startup conditions.

Crystals Part Context

This crystal belongs to Suntsu's SXT series of surface-mount resonators. Similar variants include the SXT22412DD38-37.400M, which shares the frequency but differs in temperature rating. Other models like SXT22412DD16-38.400M offer different frequencies within the same package family. These components are standardized for mass production in general-purpose electronic devices.

Crystals Replacement Considerations

Direct substitutes must match the 37.4 MHz frequency, 12 pF load capacitance, and 4-SMD no-lead package. Verify equivalent electrical parameters such as ESR and stability. Cross-reference with other manufacturers offering SMD2520-4P crystals. Ensure thermal characteristics meet the application requirements if operating outside the commercial range.
