Crystals Procurement Notes

Verify the specific ordering suffix to ensure compatibility with target circuit load capacitance requirements. Confirm that the moisture barrier bag packaging is intact prior to soldering to prevent humidity-induced performance degradation. Cross-reference the manufacturer's latest datasheet for reflow soldering profile recommendations to maintain component integrity during assembly.

Crystals Selection Notes

Select this component when a 39 MHz fundamental frequency is required for wireless SoC integration. Ensure the application circuit matches the 10 pF load capacitance specification to achieve the stated ±10 ppm accuracy. Consider the 2.0 x 1.6 mm footprint constraints against available board space and thermal management needs for the final design.

Crystals Part Context

This part belongs to Siward's series of miniature surface-mount crystals intended for high-frequency applications.
