Crystals Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the target circuit design before procurement. Confirm that the 200 Ohm ESR aligns with the oscillator circuit's drive level limitations to prevent over-driving the crystal. Ensure the HC-49/US footprint matches the PCB layout specifications. Cross-reference the RoHS compliance status with current environmental regulations applicable to the final assembly region.

Crystals Selection Notes

Select this component when a standard surface mount footprint compatible with HC-49/US dimensions is required for space-constrained designs. Choose this part if the application demands a fundamental frequency near 3.6864 MHz with moderate stability requirements. Consider the ±30 ppm initial tolerance and ±50 ppm stability limits against the system's total allowable frequency error budget. Evaluate the 1000 µW drive level capability to ensure compatibility with low-power oscillator topologies.
