Crystals Procurement Notes

Verify the specific datasheet version and RoHS compliance status before finalizing procurement decisions. Confirm that the 4-SMD package dimensions align with your PCB layout requirements. Ensure that the ±10 ppm frequency tolerance meets the system's timing accuracy specifications. Check for any export restrictions or additional documentation requirements associated with this component class.

Crystals Selection Notes

Select this component when a small form factor is critical for wearable or portable electronics. The 16 MHz frequency is suitable for standard clocking needs in low-power devices. Consider the 7 pF load capacitance to ensure proper circuit oscillation. Evaluate the 200 Ohm ESR against the oscillator circuit design constraints to guarantee reliable startup and operation.

Crystals Part Context

This part belongs to the KX-2 series of quartz crystals from Geyer Electronic America, Inc. The series is characterized by its super ultra-miniature footprint, targeting markets requiring high-density packaging. It serves as a frequency reference solution within the broader portfolio of frequency control products offered by the manufacturer.

Crystals Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching the 16 MHz frequency, 7 pF load capacitance, 200 Ohm ESR, and 4-SMD package dimensions with alternative manufacturers' offerings.
