Crystals Procurement Notes

Verify the specific suffix codes against official Suntsu documentation to confirm exact electrical parameters, particularly regarding load capacitance and temperature range variations. Ensure compatibility with existing PCB footprints due to the unique 2.0x1.6mm package dimensions. Cross-reference datasheet specifications for ESR limits to guarantee oscillator circuit reliability under operating conditions.

Crystals Selection Notes

Select this component when minimizing board space is critical while maintaining moderate timing precision. The 12pF load capacitance requires matching with the host microcontroller or oscillator circuit's input capacitance. Consider the -20°C to +70°C operating range suitability for consumer-grade environments rather than industrial or automotive applications requiring wider thermal coverage.

Crystals Part Context

This part belongs to the SXT214 series of ceramic surface-mount crystals from Suntsu Electronics. The series is characterized by its ultra-small 2.0x1.6mm footprint, catering to modern miniaturization trends in portable electronics. Variations within the series differ primarily in frequency, load capacitance, and tolerance specifications, allowing designers to tailor timing solutions to specific application requirements without changing the physical package.

Crystals Replacement Considerations

Direct substitutes must match the 2.0x1.6mm 4-SMD package, 25MHz frequency, 12pF load capacitance, and ±20ppm stability. Verify that alternative manufacturers offer comparable ESR values and AT-cut technology to ensure identical oscillation behavior and startup characteristics in the target circuit.
