Crystals Procurement Notes

Verify the specific datasheet revision and electrical parameters against the manufacturer's official documentation before procurement. Ensure that the load capacitance requirements of the target circuit match the 12.5 pF specification to maintain frequency accuracy. Confirm package compatibility with automated assembly processes.

Crystals Selection Notes

Select this component when a precise 32.768 kHz reference is required for timekeeping functions. Consider the ±20 ppm tolerance and 50 kOhms ESR limits relative to the oscillator circuit design. Evaluate the 2-SMD footprint constraints for PCB layout optimization in space-sensitive designs.

Crystals Part Context

This part belongs to the family of quartz crystals produced by Shenzhen SCTF Electronics. It serves as a passive frequency control element distinct from active oscillators. The model designation indicates specific electrical and mechanical attributes defined by the manufacturer's internal coding system for quality assurance.

Crystals Replacement Considerations

Direct substitutes must match the 32.768 kHz frequency, 12.5 pF load capacitance, and 2-SMD package dimensions. Verify equivalent ESR and tolerance specifications to ensure circuit stability. Cross-reference with other manufacturers' 32.768 kHz SMD crystals if supply chain adjustments are necessary.
