Crystals Procurement Notes

Verify the specific suffix DC27 against the manufacturer's official datasheet to confirm the exact electrical characteristics, including ESR and load capacitance values. Ensure the selected variant meets the required operating temperature range and frequency stability specifications for the target application environment before finalizing procurement.

Crystals Selection Notes

Select this component when a compact 2520 footprint is required alongside superior noise immunity provided by the four-pad configuration. The 22.1184 MHz frequency is suitable for standard serial communication interfaces. Confirm that the ±20 ppm tolerance aligns with the system clock requirements and that the industrial temperature rating covers the operational conditions.

Crystals Part Context

This part belongs to the SXT224 series of ceramic surface-mount crystals from Suntsu Electronics. The series utilizes AT-cut quartz technology for stable oscillation. The 2520 package size allows for high-density PCB layouts, making it appropriate for space-constrained consumer electronics and industrial control systems requiring reliable timing references.

Crystals Replacement Considerations

Direct substitutes include other 22.1184 MHz crystals in 2520-4 packages with matching 20 pF load capacitance and similar ESR limits. Verify pin compatibility and thermal performance when cross-referencing with alternative manufacturers' offerings.
