Crystals Procurement Notes

Verify the specific part number SXT32419CA16-40.000M against official Suntsu Electronics documentation to confirm electrical parameters such as 40 MHz frequency, 19 pF load capacitance, and 40 Ohm ESR. Ensure compliance with RoHS standards if required by your design specifications. Cross-reference datasheets for exact mechanical dimensions and soldering recommendations.

Crystals Selection Notes

Select this component when a 40 MHz reference signal with ±25 ppm tolerance is required. The 19 pF load capacitance must match the oscillator circuit design. The 4-SMD no-lead package suits high-density PCB layouts. Consider thermal stability and aging characteristics if long-term frequency accuracy is critical for the application environment.

Crystals Part Context

This crystal belongs to the SXT32419CA16 series from Suntsu Electronics, which offers various frequencies within the same physical footprint. Similar models include SXT32419CA16-38.400M and SXT32419CA16-48.000M, sharing identical packaging and general electrical characteristics but differing in operating frequency. This series supports standardized surface-mount assembly processes.

Crystals Replacement Considerations

Direct substitutes may include other 40 MHz crystals with 19 pF load capacitance and compatible ESR values in a 4-SMD no-lead package. Verify pin compatibility and electrical specs before substitution.
