Crystals Procurement Notes

Verify that the specific part number matches the required 8 MHz frequency and 18pF load capacitance specifications. Confirm that the HC-49/US surface mount footprint aligns with the PCB design constraints. Ensure the operating temperature range meets the environmental requirements of the final application. Check for compliance with RoHS3 regulations if required by the project standards.

Crystals Selection Notes

Select this component when a surface-mount solution is preferred over through-hole crystals for space-constrained designs. The 70 Ohm ESR value must be compatible with the oscillator circuit's drive level requirements. Consider the ±15ppm tolerance for applications demanding high frequency accuracy. The fundamental mode operation simplifies circuit design compared to overtone crystals.
