Crystals Procurement Notes

Verify that the supplier provides official datasheets confirming the 14.7456 MHz frequency and 19 pF load capacitance specifications. Ensure the component meets the required ±20 ppm stability tolerance for your application. Check for RoHS compliance if environmental regulations apply. Confirm the 4-SMD package dimensions match your PCB footprint exactly. Request batch testing reports if consistent ESR values are critical for your oscillator circuit design.

Crystals Selection Notes

Choose this component when space constraints require a small 2520 footprint but electromagnetic interference suppression is necessary. The four-pad design offers superior noise immunity compared to two-pin variants, making it suitable for sensitive RF sections. Select this model if your oscillator circuit is optimized for a 19 pF load and requires ±20 ppm stability. Consider the 120 Ohm ESR value when designing the drive level to prevent over-driving the crystal. This part is ideal for industrial or commercial applications where long-term frequency stability is paramount.

Crystals Part Context

This crystal belongs to the SXT224 series from Suntsu Electronics, Inc., which focuses on small-form-factor ceramic surface-mount crystals. The series is engineered for high-volume production and offers various frequency and tolerance options. The SXT224 series is commonly used in portable electronics and wireless devices where size and performance balance is critical. Other members of this family share similar physical dimensions but differ in frequency, stability, and temperature range specifications.

Crystals Replacement Considerations

Direct substitutes must match the 14.7456 MHz frequency, 19 pF load capacitance, and 4-SMD package. Verify that alternative components offer equal or better frequency stability and ESR ratings. Ensure the replacement supports the same operating temperature range. Cross-reference pinout configurations to guarantee compatibility with existing PCB footprints. Consult manufacturer cross-reference tools for verified equivalents.
