Crystals Procurement Notes

Verify the specific ordering suffix against official ECS documentation to ensure correct packaging and variant selection. Confirm that the required load capacitance matches the target circuit design. Check for updated datasheets regarding moisture sensitivity levels and reflow soldering profiles before integration into production lines.

Crystals Selection Notes

Select this component when a small form factor is critical alongside moderate frequency stability requirements. The 8 pF load capacitance must align with the oscillator circuit's input capacitance. Consider the 80 Ohm ESR limit to ensure reliable oscillation startup in the host application environment.

Crystals Part Context

This part belongs to the ECX-1637 series of tight-tolerance super miniature crystals. The series is characterized by its reduced physical size compared to standard packages while maintaining electrical performance suitable for consumer electronics and portable devices requiring precise timing references.

Crystals Replacement Considerations

Cross-reference with other 24 MHz SMD crystals featuring 8 pF load capacitance and similar dimensions. Ensure substitute parts match the 80 Ohm ESR maximum and ±10 ppm stability specifications to maintain circuit compatibility.
