Crystals Procurement Notes

Verify the specific part number against official Suntsu Electronics documentation to confirm electrical parameters such as ESR and load capacitance. Ensure the ordering suffix matches the required frequency tolerance and stability specifications. Confirm that the 4-SMD package type aligns with the assembly process capabilities. Cross-reference the temperature range requirements with the application environment to ensure compliance with the -30°C to +85°C operational limits.

Crystals Selection Notes

Select this component when space constraints require a 1.6mm x 1.2mm footprint. Consider the 150 Ohm ESR limit for circuit matching compatibility. Verify that the ±25 ppm tolerance meets the system timing accuracy requirements. Ensure the 9 pF load capacitance matches the host controller's internal or external capacitor configuration. Confirm the industrial temperature rating suits the deployment environment.

Crystals Part Context

This component belongs to the SXT114 series of ultra-small crystals designed for portable and wearable electronics. The series offers various frequency options within the 24 MHz to 54 MHz range. Different suffixes indicate variations in tolerance, stability, and temperature ranges. The 4-pad design provides improved electromagnetic interference immunity compared to 2-pad alternatives.

Crystals Replacement Considerations

Substitutes must match the 1.6mm x 1.2mm 4-SMD package and 24 MHz frequency. Verify equivalent ESR and load capacitance values to prevent start-up issues. Check if alternative parts offer compatible temperature ranges and stability specifications.
