Crystals Procurement Notes

Verify the specific package dimensions and lead configuration against the target PCB footprint prior to integration. Confirm that the operating temperature range meets the environmental requirements of the final application. Ensure compatibility with the host circuit's load capacitance specifications to maintain accurate frequency performance. Cross-reference the manufacturer datasheet for handling and soldering guidelines.

Crystals Selection Notes

Select this component when a 25 MHz fundamental frequency is required with moderate stability specifications. Consider the 4-SMD package size for space-constrained designs where through-hole mounting is not feasible. Evaluate the -20°C to +70°C temperature range against operational extremes. Compare ESR values with driver circuit capabilities to ensure reliable oscillation startup.
