Crystals Procurement Notes

Verify the specific suffix METC-T against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure the ordering quantity aligns with the supplier's minimum packaging requirements. Cross-reference the load capacitance value with the target circuit design to guarantee accurate frequency performance. Confirm that the operating temperature range meets the environmental requirements of the intended application before finalizing procurement.

Crystals Selection Notes

Select this component when a small form factor and high stability are required for 37.4 MHz applications. The 9 pF load capacitance must match the system's input capacitance to maintain accuracy. Consider the ±10 ppm tolerance for timing-sensitive designs. Evaluate the 80 Ohm ESR against the driving circuit capabilities to ensure proper oscillation startup. Compare thermal performance against the -40°C to +85°C range if extreme environmental conditions are expected.

Crystals Part Context

This part belongs to the 8Q series of quartz crystals from TXC Corporation, which focuses on miniature surface-mount devices. The series is characterized by low profile dimensions and stable frequency characteristics. The 8Q-37.400METC-T specifically addresses the need for compact timing solutions in modern electronics where board space is limited but precision is critical.

Crystals Replacement Considerations

Direct substitutes include other 37.4 MHz crystals with identical 1.6x1.2mm packages and ±10 ppm stability. Verify that alternative parts support the same 9 pF load capacitance and 80 Ohm ESR. Check for compatible operating temperature ranges and supply voltage requirements to ensure functional equivalence without circuit modification.
