Crystals Procurement Notes

Verify the exact datasheet version from Suntsu Electronics to confirm current specifications, as parameters may vary between production batches. Ensure compatibility with your PCB footprint design, specifically the 4-SMD no-lead package dimensions. Cross-reference the frequency tolerance and load capacitance values against your circuit schematic requirements before finalizing procurement decisions.

Crystals Selection Notes

Select this component when a 12 MHz reference is required with ±20ppm initial accuracy. Consider the 100 Ohm ESR value for drive level sensitivity in your oscillator circuit design. The 19pF load capacitance must match the external capacitors used in the application to ensure correct frequency operation. Evaluate thermal constraints if operating near the upper temperature limits.

Crystals Part Context

This part belongs to the SXT32419 series of surface-mount crystals from Suntsu Electronics. The series offers various frequencies and package options for different timing needs. The DB17 suffix typically indicates specific dimensional and electrical characteristics within this product line, distinguishing it from other variants like CB17 or DD38 which may have different stability or temperature ranges.

Crystals Replacement Considerations

Direct substitutes include other 12 MHz crystals with identical 4-SMD no-lead footprints, 19pF load capacitance, and similar ESR values. Verify that any replacement maintains the ±20ppm tolerance requirement. Check manufacturer-specific mounting recommendations to ensure mechanical reliability during reflow soldering processes.
