Crystals Procurement Notes

Verify current availability status as the component may be subject to discontinuation or limited supply. Confirm that the 18 pF load capacitance matches the target circuit design requirements. Ensure the ±30 ppm tolerance aligns with system clock accuracy needs. Check RoHS exemption documentation if required for specific certification standards. Validate package dimensions against PCB footprint constraints.

Crystals Selection Notes

Select this component when a 12 MHz reference signal is required for compact electronic designs. The 3225 package size suits space-constrained layouts. The -40°C to +85°C temperature range covers most industrial and commercial environments. Consider the 80 Ohm ESR value for oscillator circuit stability. The glass seal offers reliability benefits for harsh conditions where standard crystals might fail.
