Crystals Procurement Notes

Verify the specific package variant and tolerance requirements against the target circuit design before procurement. Ensure that the supply chain source provides original manufacturer documentation to confirm RoHS compliance and material authenticity. Cross-reference the part number with official Meritek catalogs to avoid counterfeit components or incorrect frequency tolerances during the sourcing process.

Crystals Selection Notes

Select this component when a precise 32.768 kHz frequency is required for timekeeping functions. Consider the 12.5 pF load capacitance requirement to ensure oscillator circuit stability. Evaluate the 70 kOhm resistance limit against the oscillator's drive level specifications to prevent overdriving the crystal. Confirm that the SMD4115-2P footprint matches the PCB layout constraints.

Crystals Part Context

This crystal belongs to Meritek’s standard line of surface-mount resonators designed for cost-effective mass production. It serves as a critical timing element in digital systems where accurate second-based counting is necessary. The two-terminal design simplifies board space utilization compared to traditional three-pin packages while maintaining reliable oscillation characteristics for general-purpose embedded applications.

Crystals Replacement Considerations
