Crystals Procurement Notes

Verify the exact operating temperature range and aging rate requirements against your specific application environment before ordering. Confirm that the 4-SMD no-lead footprint matches your PCB design constraints. Ensure that the ±50 ppm frequency tolerance meets the system timing budget. Request the latest datasheet from the manufacturer to confirm any recent revisions to the mechanical dimensions or material composition. Validate compatibility with your reflow soldering profile to prevent thermal damage during assembly.

Crystals Selection Notes

Select this component when a fixed frequency of 24.576 MHz is required without the need for external tuning capacitors beyond the specified load capacitance. Consider the 4-SMD no-lead package if space constraints are critical and automated placement equipment is available. Evaluate the ±50 ppm tolerance against the jitter sensitivity of your downstream logic. Compare the 50 Ohm ESR against the drive level limitations of your oscillator circuit to ensure long-term reliability and avoid over-driving the crystal element.
