Crystals Procurement Notes

Verify the specific suffix against the manufacturer's official datasheet to confirm exact electrical tolerances and aging rates. Ensure the ordering code matches the required load capacitance and frequency stability specifications for the target application. Cross-reference the package dimensions with PCB footprint libraries to guarantee mechanical compatibility during procurement.

Crystals Selection Notes

Select this component when a 12 MHz reference is required in a compact surface-mount form factor. Consider the 80 ohm ESR and 18 pF load capacitance requirements for circuit matching. Evaluate the ±10 ppm initial tolerance against system timing accuracy needs. Confirm that the -40°C to +85°C operating range aligns with the environmental conditions of the end product.

Crystals Part Context
