Crystals Procurement Notes

Verify the specific suffix 'B' against the official Meritek datasheet to confirm exact mechanical dimensions and electrical tolerances. Ensure the supplier provides traceability documentation matching the manufacturer's part number. Confirm RoHS compliance status through the provided certificate of conformity. Cross-reference the package type to ensure compatibility with the intended PCB footprint and assembly process requirements.

Crystals Selection Notes

Select this component when a low-frequency, high-stability reference is required for timekeeping functions. The 32.768 kHz frequency allows for efficient binary division in digital counters. Consider the 12.5 pF load capacitance requirement when designing the oscillator circuit to ensure accurate frequency output. Evaluate the 50 kOhm maximum resistance limit against the oscillator amplifier capabilities to guarantee reliable startup and sustained oscillation.
