Crystals Procurement Notes

Verify the specific suffix FA27 against official Suntsu documentation to confirm package dimensions and pin configuration. Ensure the required frequency tolerance of ±10 ppm aligns with system design constraints. Cross-reference the operating temperature range of -30°C to +85°C with environmental specifications. Confirm that the 18 pF load capacitance matches the host circuit's requirements before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 12.288 MHz reference is required with moderate stability. The 120 Ohm ESR limit suits standard parallel resonant circuits. Consider the 4-SMD package size for board space optimization. Verify compatibility with reflow soldering profiles specified in the datasheet. Ensure the host oscillator circuit can drive the specified load capacitance effectively.

Crystals Part Context

This part belongs to the SXT22418 series of surface-mount crystals from Suntsu Electronics. The series offers various frequencies and tolerances. The FA27 suffix typically denotes specific packaging or tolerance grades within the product line. These components are commonly used in consumer electronics and industrial control systems where reliable timing is essential.

Crystals Replacement Considerations

Direct substitutes must match the 12.288 MHz frequency, 18 pF load capacitance, and 4-SMD package. Check if alternative manufacturers offer comparable ±10 ppm tolerance and similar ESR values. Verify thermal performance meets the -30°C to +85°C requirement. Ensure mechanical dimensions are compatible with existing footprints.
