Procurement Notes

Verify the specific load capacitance requirement of 6pF against the target circuit design to ensure frequency accuracy. Confirm that the operating environment remains within the specified -20°C to +70°C range. Check for compatibility with standard reflow soldering profiles as indicated by the manufacturer's lead-free specifications. Ensure the ESR value aligns with the oscillator circuit's drive level limitations.

Selection Notes

Select this component when a 25 MHz fundamental frequency is required with a 6pF load capacitance specification. Consider the 80 Ohm ESR limit for oscillator circuit stability. Evaluate the 4-SMD package size against available board space constraints. Verify that the ±30 ppm frequency tolerance meets the system's timing precision requirements compared to higher-grade alternatives.
