Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to ensure compatibility with required tolerance and packaging specifications. Confirm that the 4-SMD no-lead package matches the target PCB footprint. Cross-reference the 16pF load capacitance requirement with the circuit design to prevent frequency deviation. Ensure the supplier is an authorized dealer to guarantee genuine components and traceability.

Crystals Selection Notes

Select this component when a compact 8 MHz reference is needed for portable audio or wireless devices. The choice depends on the strict adherence to the 16pF load capacitance and the availability of a no-lead SMD package. Evaluate the ±50 ppm tolerance against the system's clock accuracy requirements. Consider the physical dimensions relative to other available crystals in the KX-2 series for optimal board layout efficiency.

Crystals Part Context

This part belongs to the KX-2 series from Geyer Electronic, characterized by super ultra-miniature footprints.
