Crystals Procurement Notes

Verify the specific tolerance variant required, as the part number may correspond to either ±30 ppm or ±50 ppm specifications depending on the manufacturing batch or suffix configuration. Confirm the load capacitance matches the target circuit design requirements. Ensure the HC49S footprint aligns with the PCB layout constraints. Check RoHS compliance status if environmental regulations apply to the final assembly. Validate the operating temperature range against the intended application environment.

Crystals Selection Notes

Select this component when a stable, low-cost surface mount crystal is needed for fundamental frequency generation. The HC49S package offers a balance between size and performance for general-purpose timing. Consider the ±30 ppm option for higher precision needs or ±50 ppm for cost-sensitive designs. Ensure the 20 pF load capacitance is compatible with the oscillator circuit's input capacitance. Evaluate thermal stability requirements before choosing this specific temperature grade.

Crystals Part Context
