Crystals Procurement Notes

Verify that the specific part number matches the required frequency tolerance and temperature range specifications for your application. Confirm that the 20pF load capacitance aligns with your circuit design requirements. Ensure compatibility with standard SMT assembly processes given the 3225 footprint dimensions. Cross-reference the datasheet for any specific handling or storage recommendations provided by the manufacturer.

Crystals Selection Notes

Select this component when a compact 3225 form factor is necessary alongside robust EMI shielding capabilities offered by the four-pad layout. Consider this model for designs operating between -30°C and +85°C where ±50 ppm stability is sufficient. Evaluate the 70 Ohm ESR against your oscillator circuit's drive level constraints to ensure optimal performance and longevity without over-driving the crystal element.

Crystals Part Context

This component belongs to the SXT324 series, which represents Suntsu Electronics' line of industrial-grade surface-mount crystals. The series is characterized by its small 3225 footprint and four-terminal configuration, distinguishing it from traditional two-pad variants. This specific model targets applications requiring reliable timing sources in space-constrained consumer and industrial electronics.

Crystals Replacement Considerations

Direct substitutes must match the 19.6608 MHz frequency, 20pF load capacitance, 3225-4P package, and -30 to +85°C operating range. Verify equivalent ESR values and frequency tolerance ratings to maintain circuit stability. Consult manufacturer cross-reference lists for verified compatible alternatives.
