Crystals Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to confirm exact electrical parameters, including load capacitance, frequency tolerance, and operating temperature range. Ensure the selected variant matches the required ESR limits for your oscillator circuit design to guarantee reliable startup performance.

Crystals Selection Notes

Select this component when space constraints require a 2520 package but superior noise immunity is needed over standard two-pin crystals. The four-pad design aids in reducing radiated emissions, making it ideal for RF-sensitive environments like Bluetooth or Zigbee applications where signal integrity is critical.

Crystals Part Context

This part belongs to the SXT224 series, a line of industrial-grade 4-pad ceramic SMD crystals designed for small form-factor electronics. The series emphasizes robustness against electromagnetic interference through its grounded shield structure, catering to modern consumer and industrial devices that demand precise timing in minimal board space.

Crystals Replacement Considerations

Direct substitutes must match the 2520 4-pad package, 20MHz frequency, 8pF load capacitance, and ±50ppm tolerance. Verify ESR compatibility and operating temperature range (-10°C to +60°C or 0°C to +70°C variants exist) before cross-referencing with other manufacturers' offerings.
