Crystals Procurement Notes

Verify the exact part number against official Suntsu Electronics datasheets to ensure compatibility with specific circuit requirements. Confirm that the 4-SMD package dimensions match the target PCB footprint. Check for any specific handling instructions regarding electrostatic discharge sensitivity during storage and assembly. Ensure the supplier provides traceability documentation consistent with industry standards for electronic components.

Crystals Selection Notes

Select this component when a 20 MHz reference signal is required with moderate stability in space-constrained designs. The 16 pF load capacitance must align with the oscillator circuit's input specifications. Consider the 50 Ohm ESR value for impedance matching purposes. The wide temperature range makes it suitable for industrial or automotive environments where standard commercial grade parts may fail.

Crystals Part Context

This crystal belongs to the SXT series of surface-mount resonators from Suntsu Electronics. These components are engineered for high-frequency stability in digital systems. The specific model utilizes quartz technology to maintain accurate timing signals. It is distinct from other series like SXT224 which may offer different package sizes or electrical characteristics.

Crystals Replacement Considerations

Direct substitutes include other 20 MHz crystals with identical 16 pF load capacitance and 4-SMD packaging. Verify that alternative parts meet the same ±50 ppm tolerance and -40°C to +85°C temperature range. Cross-reference pinout configurations if using leaded alternatives, though direct surface-mount replacements are preferred for mechanical consistency.
