Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure compatibility with required tolerance and packaging specifications. Confirm that the requested quantity aligns with current production lead times, as supply chain fluctuations may impact delivery schedules. Ensure all technical parameters match the design requirements before finalizing purchase orders.

Crystals Selection Notes

Select this component when a stable 13.56 MHz reference is required for RFID or wireless protocols. The 16 pF load capacitance must match the oscillator circuit design to maintain accuracy. Consider the 60 Ohm ESR for drive level sensitivity. The wide temperature range makes it suitable for harsh industrial settings where standard commercial grade crystals might fail.

Crystals Part Context

This crystal belongs to Geyer Electronic America's KX-9A series of surface-mount resonators. These components are engineered for compact electronic designs requiring reliable frequency generation. The series offers various frequency options within a standardized footprint, facilitating easy integration into modern PCB layouts without significant redesign efforts.

Crystals Replacement Considerations

Direct substitutes must match the 13.56 MHz frequency, 16 pF load capacitance, and 4-SMD no-lead package dimensions. Verify equivalent ESR values and frequency stability ratings to ensure circuit performance remains unchanged during replacement.
