Crystals Procurement Notes

Verify the specific manufacturer datasheet to confirm exact electrical parameters and mechanical dimensions before integration. Ensure compatibility with reflow soldering profiles suitable for ceramic SMD crystals. Confirm that the 18 pF load capacitance matches the circuit design requirements to maintain accurate frequency performance.

Crystals Selection Notes

Select this component when a cost-effective ceramic alternative to quartz is required for non-critical timing applications. The 40 Ohm ESR and 18 pF load capacitance define the oscillator circuit requirements. Consider the ±30 ppm tolerance against system jitter specifications. Verify package availability for automated assembly processes.

Crystals Part Context

This part belongs to Geyer Electronic's line of ceramic resonators and crystals. Ceramic components typically offer lower cost and higher shock resistance compared to quartz but may exhibit wider frequency drift over temperature. They are commonly used in consumer electronics where tight frequency accuracy is not paramount.

Crystals Replacement Considerations

Direct substitutes must match the 12.88498 MHz frequency, 4-pad SMD footprint, and 18 pF load capacitance. Verify ESR limits and tolerance grades. Cross-reference with other manufacturers' ceramic SMD crystals offering similar dimensional constraints and electrical characteristics.
