Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to ensure compatibility with required tolerance and packaging specifications. Confirm that the 12.5 pF load capacitance aligns with the target circuit design before procurement. Request RoHS compliance documentation to verify environmental standards adherence. Ensure storage conditions meet moisture sensitivity level requirements prior to soldering.

Crystals Selection Notes

Select this component when a precise 32.768 kHz reference is required for timekeeping or low-frequency synchronization. The ±20 ppm tolerance suits general-purpose applications where high stability is not critical. Consider the 70 kOhm ESR value for oscillator circuit matching. Evaluate the 3.2x1.5mm footprint against available board space constraints during the initial design phase.
