Crystals Procurement Notes

Verify that the specific part number matches the required load capacitance and temperature range for your circuit design. Confirm RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure compatibility with your reflow soldering profile given the ceramic package construction. Cross-reference the datasheet for any specific handling instructions related to the four-pad layout to prevent solder bridging during assembly.

Crystals Selection Notes

Select this component when a compact 3225 footprint is required alongside improved noise immunity provided by the four-terminal configuration. The ±25ppm stability suits general industrial timing needs where extreme precision is not critical. Consider the -20°C to +70°C range against your environmental operating conditions. This model is suitable for designs prioritizing board density without sacrificing signal integrity through dedicated ground pads.

Crystals Part Context

This crystal belongs to the SXT324 series, which defines a family of 3.2mm x 2.5mm industrial-grade surface-mount crystals. The series is characterized by its four-pad architecture, distinguishing it from traditional two-pad variants.
