Crystals Procurement Notes

Verify the specific lot code and date code upon receipt to ensure compliance with project timelines. Confirm that the delivered components match the exact part number designation, including suffix variations, as these may indicate differences in packaging or initial calibration tolerances. Request the manufacturer's certificate of conformity to validate material composition and RoHS compliance status before integration into production lines.

Crystals Selection Notes

Select this component when a compact 2520 footprint is required alongside superior electromagnetic interference suppression. The four-pad architecture facilitates direct connection to ground planes, reducing radiated emissions in sensitive RF environments. Ensure the circuit design accommodates the 80 Ohm ESR specification to guarantee reliable startup across the intended operating temperature range without excessive drive level requirements.

Crystals Part Context

This part belongs to the SXT224 series of industrial-grade ceramic surface-mount crystals. The series offers various frequency options and tolerance grades tailored for wireless and portable electronics. The 2520 package size balances board space efficiency with electrical performance, making it suitable for applications where larger packages are impractical but reliability remains critical.

Crystals Replacement Considerations

Direct substitutes include other 20 MHz crystals in the 2520 SMD package with matching 8pF load capacitance and similar ESR values. Verify pin compatibility and thermal characteristics when cross-referencing with alternative manufacturers' offerings to maintain signal integrity.
