Crystals Procurement Notes

Verify the specific suffix S315-054 against official Siward documentation to confirm exact electrical parameters and packaging specifications. Ensure compatibility with reflow soldering profiles defined in the manufacturer datasheet. Cross-reference the 4-SMD footprint with board design files to prevent assembly errors.

Crystals Selection Notes

Select this component when a 40 MHz reference with ±8 ppm stability is required in a small form factor. Consider the 10 pF load capacitance requirement for oscillator circuit design. Evaluate the 40 Ohm ESR against the driving capability of the target microcontroller or oscillator IC.

Crystals Part Context

This part belongs to the XTL50 series of surface-mount crystals from Siward Crystal Technology Co., Ltd. The series offers various frequencies and packages optimized for consumer electronics and industrial control systems.
