• Surface-mount design facilitates efficient PCB integration

Crystals Applications

• Precision timing circuits requiring strict frequency accuracy
• Microcontroller clock sources demanding reliable oscillation
• Communication modules utilizing standard baud rates

Crystals Procurement Notes

Verify the specific suffix configuration against the manufacturer's official documentation to ensure compatibility with required tolerance and stability specifications. Confirm that the 4-SMD footprint matches the target PCB layout dimensions. Check RoHS compliance status if environmental regulations apply to the final product assembly. Ensure storage conditions maintain component integrity prior to soldering.

Crystals Selection Notes

Select this component when a 20 MHz fundamental frequency with ±15 ppm tolerance is required. The 18 pF load capacitance must match the oscillator circuit design parameters. Consider the 80 Ohm ESR value for drive level sensitivity. The surface-mount package requires appropriate reflow soldering profiles suitable for lead-free assemblies.

Crystals Part Context

This part belongs to the SXT22418 series of surface-mount crystals from Suntsu Electronics. The series offers various frequencies and tolerances within a standardized 4-SMD form factor. These components are engineered for general-purpose timing applications where space constraints and automated placement efficiency are prioritized over through-hole alternatives.

Crystals Replacement Considerations

Direct substitutes include other 20 MHz crystals with identical 18 pF load capacitance and comparable ESR values. Verify pinout compatibility for the 4-SMD no-lead package. Cross-reference frequency stability requirements to ensure equivalent performance in the target application environment.
