• Communication equipment oscillators

Crystals Procurement Notes

Verify the specific lot date code and packaging quantity against current distributor listings, as supply chain conditions may vary. Confirm that the 4-SMD footprint matches your PCB layout requirements precisely. Ensure that the ±30 ppm tolerance meets your system's frequency accuracy needs before finalizing procurement orders.

Crystals Selection Notes

Select this component when a standard 8 MHz fundamental frequency is required in a compact surface-mount form factor. The 100 Ohm ESR suggests suitability for standard oscillator circuits without excessive loading. Consider the -20°C to +70°C temperature range to ensure adequate performance for commercial or industrial environments where extreme cold or heat is not expected.

Crystals Part Context

This part belongs to Geyer Electronic's line of quartz crystals and resonators. The manufacturer specializes in frequency control products including oscillators and filters. The 12.89007 designation identifies a specific SMD variant within their broader catalog of ceramic and quartz components used for precise timing applications.

Crystals Replacement Considerations

Direct substitutes must match the 8 MHz frequency, 16 pF load capacitance, and 4-SMD package dimensions. Verify that alternative manufacturers offer comparable ±30 ppm tolerance and similar ESR values to maintain circuit stability.
