Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's official naming convention to ensure correct tolerance and temperature range. Confirm that the required load capacitance matches the circuit design requirements, as standard values may vary. Check for any special handling instructions regarding moisture sensitivity level before soldering, although some variants are MSL 1 compliant. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Crystals Selection Notes

Select this component when space constraints require a sub-0402 footprint with enhanced grounding via four pads. Consider the ±25 ppm tolerance for applications where moderate precision is sufficient without active temperature compensation. Evaluate the 150 Ohm ESR against the oscillator circuit's drive level requirements to prevent over-driving the crystal. Compare alternative frequencies within the 24-54 MHz range if different clock speeds are needed for the target application.

Crystals Part Context

This part belongs to the SXT114 series of ultra-small quartz crystals from Suntsu Electronics. The series is characterized by its 1.6x1.2mm 4-pad form factor, which offers improved interference rejection compared to traditional 2-pad designs. The series supports various frequency tolerances and temperature ranges, catering to both consumer and industrial electronics markets requiring compact timing solutions.

Crystals Replacement Considerations

Direct substitutes include other 1.6x1.2mm 4-pad crystals with identical 25 MHz frequency, 7pF load capacitance, and ±25ppm tolerance. Verify mechanical compatibility and electrical parameters such as ESR and drive level before substitution.
