Crystals Procurement Notes

Verify the specific load capacitance requirement of 18 pF against the target circuit design to ensure frequency accuracy. Confirm that the operating environment remains within the -20°C to +70°C range. Check for RoHS compliance status if environmental regulations apply to the final product assembly.

Crystals Selection Notes

Select this component when a 20 MHz reference is required with moderate stability needs. Ensure the application circuit can accommodate the 18 pF load capacitance specification. Consider the physical dimensions of the 3.2 mm x 2.5 mm package for layout constraints compared to larger through-hole alternatives.

Crystals Part Context

This part belongs to the 7M series of quartz crystals manufactured by TXC Corporation. The series focuses on standard surface mount resonators designed for cost-effective timing solutions in consumer and industrial electronics. It serves as a passive frequency-determining element requiring external oscillator circuitry.

Crystals Replacement Considerations

Direct substitutes include other 20 MHz SMD crystals with matching 18 pF load capacitance and similar footprint dimensions. Verify ESR limits and temperature stability before swapping manufacturers.
