Crystals Procurement Notes

Verify the specific suffix and package variant against the official Suntsu Electronics datasheet to ensure compatibility with your PCB layout. Confirm that the ±30 ppm tolerance meets your system's jitter requirements. Check for RoHS compliance status if required by your manufacturing standards. Ensure storage conditions align with moisture sensitivity levels specified in the product documentation before assembly.

Crystals Selection Notes

Choose this component when a small form factor is critical alongside moderate frequency stability. The 12pF load capacitance must match the oscillator circuit design. Consider the 100 Ohm ESR limit for drive level constraints. This part suits applications requiring reliable performance in varying thermal environments without needing high-end automotive or military grade specifications.

Crystals Part Context

This crystal belongs to the SXT214 series from Suntsu Electronics, which focuses on cost-effective ceramic resonators for general-purpose electronics. The series offers various frequencies and packages, balancing size and performance. The SXT21412BA16-40.000M specifically targets the 40 MHz niche, providing a standardized solution for embedded systems requiring accurate timekeeping or data synchronization.

Crystals Replacement Considerations

Direct substitutes include other 40 MHz crystals with identical 2.00x1.60mm footprints and 12pF load capacitance.
