Crystals Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature range (-40°C to +85°C) compared to commercial variants. Confirm that the 20pF load capacitance matches the target circuit design requirements. Ensure the 4-SMD package dimensions align with the PCB layout constraints. Check RoHS compliance status for regulatory adherence. Validate ESR specifications against oscillator amplifier capabilities.

Crystals Selection Notes

Select this component when an industrial temperature range is required for 25 MHz timing applications. The 4-SMD form factor suits space-constrained surface-mount assemblies. Consider the 60 Ohm ESR value for oscillator circuit stability analysis. Verify compatibility with host device input capacitance to maintain the specified ±30ppm tolerance. Evaluate lead-free manufacturing processes for environmental compliance.
