Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required load capacitance and tolerance specifications. Confirm that the 4-SMD No Lead package matches the target PCB footprint design. Check for any recent updates to the product status or recommended replacement components within the KX-2 series documentation before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 48 MHz reference signal is required in ultra-compact wearable or wireless form factors. Ensure the circuit design accommodates the 9 pF load capacitance and 40 Ohm ESR characteristics. Evaluate the ±10 ppm frequency stability against system timing requirements. Consider the ceramic SMD package constraints for thermal management and mechanical stress during assembly.

Crystals Part Context

This part belongs to the Geyer Electronic America KX-2 series, which specializes in super ultra-miniature quartz crystals. The series targets applications where physical size is a critical constraint, such as hearing aids and earbuds. Geyer Electronic positions itself as an independent manufacturer with long-term delivery guarantees, serving global markets from headquarters in Germany and regional offices.

Crystals Replacement Considerations

Consult the official Geyer Electronic datasheet for direct cross-reference part numbers within the KX-2 series. Verify if alternative frequencies or tolerance levels are available in the same package family. Do not assume functional interchangeability with other manufacturers' 48 MHz crystals without verifying pinout, load capacitance, and ESR specifications.
