Crystals Procurement Notes

Verify the specific suffix codes on the official datasheet to confirm exact electrical parameters and packaging options. Ensure that the selected variant matches the required load capacitance and ESR specifications for the target circuit design. Cross-reference the manufacturer's latest documentation to confirm compliance with current RoHS standards and availability status before finalizing procurement plans.

Crystals Selection Notes

Select this component when a compact 3225 footprint is required for low-frequency timing applications. The 4 pF load capacitance necessitates careful consideration of stray capacitance in the circuit layout. Verify that the 70 Ohm ESR aligns with the oscillator circuit's drive level requirements to prevent over-driving or failure to start.
