Crystals Procurement Notes

Verify the specific suffix EA17 against official Suntsu documentation to confirm temperature range and tolerance specifications. Ensure compatibility with standard reflow soldering profiles for SOJ packages. Cross-reference the 18pF load capacitance requirement with circuit design parameters to prevent frequency deviation during operation.

Crystals Selection Notes

Select this component when a 7.3728 MHz fundamental frequency is required with ±15 ppm accuracy. The 18pF load capacitance must match the external circuit design. Consider the 4-SOJ package dimensions for PCB layout constraints. Verify that the operating temperature range meets the application's environmental requirements before finalizing the selection.

Crystals Part Context

This part belongs to the SXT144 series of surface-mount crystals from Suntsu Electronics. The series offers various frequency options and package configurations.
