Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct frequency and tolerance specifications. Confirm that the 4-SMD no-lead package matches your PCB footprint requirements. Cross-reference the datasheet for reflow soldering profiles to prevent thermal damage during assembly. Ensure compatibility with your system's load capacitance requirements.

Crystals Selection Notes

Select this component when a 25 MHz fundamental-mode crystal is required in a small form factor. The 18 pF load capacitance must match the oscillator circuit design. Consider the ±30 ppm tolerance for applications with moderate stability needs. Verify the 120 Ohm ESR aligns with the driving circuit capabilities to ensure reliable oscillation start-up.
