Crystals Procurement Notes

Verify the specific ordering suffix against the official Abracon datasheet to ensure correct tolerance and package specifications. Confirm RoHS compliance status and environmental declarations prior to procurement. Check for any process change notifications or end-of-life notices that may affect long-term supply chain stability. Ensure the selected variant matches the required load capacitance and ESR values for the target circuit design.

Crystals Selection Notes

Select this component when a precise 18.432 MHz reference is required for microcontroller or embedded system interfaces. Consider the ±30 ppm stability and -20°C to +70°C operating range for industrial or consumer electronics. Verify that the 20 pF load capacitance aligns with the host circuit's requirements. The low-profile form factor makes it suitable for applications where vertical board space is limited compared to traditional through-hole crystals.
