Crystals Procurement Notes

Verify the specific operating temperature range and tolerance requirements against your application needs before procurement. Confirm that the SMD3225-4P package dimensions align with your PCB footprint constraints. Ensure that the 40 Ohm ESR value is compatible with your oscillator circuit design to guarantee reliable startup and sustained operation. Cross-reference the datasheet specifications with your system's electrical requirements to avoid performance issues.

Crystals Selection Notes

Select this component when a 44 MHz reference frequency with ±20 ppm accuracy is required in a small form factor. The 19 pF load capacitance makes it suitable for standard CMOS logic interfaces. Consider the 40 Ohm ESR when designing the load capacitors to ensure proper oscillation amplitude. The no-lead SMD package offers advantages in high-volume manufacturing and reduced board space compared to through-hole alternatives.

Crystals Part Context

This part belongs to Suntsu Electronics' SXT32419 series of surface-mount crystals. The series offers various frequencies and packages to meet diverse timing needs.
