Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required frequency tolerance and load capacitance specifications. Confirm that the 4-SMD No Lead package matches the target PCB footprint. Cross-reference the part number with authorized distributors to validate authenticity and avoid counterfeit components. Check for any recent updates to the KX-2 series documentation regarding environmental compliance or RoHS status before finalizing procurement orders.

Crystals Selection Notes

Select this component when a precise 19.3536 MHz reference is required for miniaturized audio or wireless devices. Ensure the system design accommodates the 12pF load capacitance requirement. Evaluate the ±50ppm stability against the application's timing accuracy needs. Consider the surface-mount form factor for high-volume production lines requiring automated placement.

Crystals Part Context

This part belongs to the KX-2 series from Geyer Electronic America, Inc., which specializes in super ultra-miniature quartz crystals.
