Procurement Notes

Verify the specific package variant and manufacturing date code against the official datasheet before integration. Confirm that the supply chain documentation aligns with RoHS3 compliance requirements. Ensure storage conditions maintain moisture sensitivity level 1 integrity until soldering. Cross-reference the manufacturer part number with authorized distributor lists to avoid counterfeit components during procurement.

Selection Notes

Select this component when a fundamental mode crystal is required for 18.432 MHz applications with moderate stability needs. The 50 Ohm ESR and 8pF load capacitance must match the oscillator circuit design specifications. Consider the 2-SMD footprint constraints for PCB layout compatibility. Evaluate the -10°C to 70°C operating range against the environmental conditions of the target application.

Part Context

This component belongs to the NX8045GB series from NDK, designed for general-purpose timing applications. It represents a standard surface-mount solution within the manufacturer's portfolio of quartz crystals. The part is distinct from higher-stability or lower-ESR variants available in other series, offering a balance of performance and form factor for common embedded systems.
