Crystals Procurement Notes

Verify the specific frequency variant required from the 12.89041 to 29.4912 MHz range, as the part number may represent a series or family identifier rather than a single fixed frequency point. Confirm package compatibility with automated pick-and-place equipment due to the no-lead SMD form factor. Ensure that the 16pF load capacitance aligns with the host circuit design requirements before finalizing procurement orders.

Crystals Selection Notes

Select this component when miniaturization is critical for wearable or portable electronics such as hearing aids and earbuds. The choice depends on the need for a quartz crystal with a low profile and leadless termination style. Evaluate the 50 Ohm ESR against the oscillator circuit's drive level constraints to ensure stable operation without overdriving the resonator element.

Crystals Part Context

This component belongs to the KX-2 series produced by Geyer Electronic America, Inc., which specializes in super ultra-miniature quartz crystals. The series targets the medical and consumer audio markets where size reduction is paramount. It complements the manufacturer's broader portfolio of oscillators and ceramic resonators by providing discrete frequency reference solutions.

Crystals Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the exact operating frequency, load capacitance, and physical dimensions of the original component to ensure functional equivalence in the target application.
