Crystals Procurement Notes

Verify the specific load capacitance requirement against the target circuit design before procurement. Confirm that the 40 Ohm maximum series resistance aligns with the oscillator driver strength capabilities. Ensure the selected footprint matches the 4-SMD no-lead package dimensions specified in the official datasheet to prevent assembly errors.

Crystals Selection Notes

Select this component when a standard 25 MHz reference is required for space-constrained designs. The 20 pF load capacitance dictates the external capacitor values needed for accurate frequency tuning. Consider the -40°C to +85°C industrial temperature range suitability for the intended operational environment.

Crystals Part Context
