Crystals Procurement Notes

Verify the specific suffix FA16 against official Suntsu documentation to confirm exact electrical parameters such as ESR and tolerance. Ensure the 18pF load capacitance matches the target circuit design requirements. Confirm the 4-SMD package dimensions align with PCB footprint constraints before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 25 MHz fundamental frequency is required in a small form factor. The 18pF load capacitance must match the oscillator circuit's external capacitors. Consider the 120 Ohm ESR limit for drive level sensitivity. Verify temperature range specifications if operating outside standard commercial limits.

Crystals Part Context

This part belongs to the SXT214 series of ceramic surface-mount crystals from Suntsu Electronics. The series offers various frequencies and packages. The SXT21418FA16 variant specifically denotes the 25 MHz frequency point within this family, sharing common mechanical characteristics with other members like the SXT21418CB27.

Crystals Replacement Considerations

Direct substitutes include other 25 MHz crystals with identical 18pF load capacitance and 4-SMD 2.0x1.6mm footprints. Verify ESR compatibility to ensure oscillator startup reliability. Cross-reference frequency tolerance requirements to maintain system timing accuracy.
