Crystals Procurement Notes

Verify the specific package dimensions and lead configuration against schematic requirements before integration. Confirm that the 65 kOhm ESR aligns with the oscillator circuit design to ensure proper startup and sustained oscillation. Ensure the ±20 ppm tolerance meets the system's timing accuracy specifications for the intended operational environment.

Crystals Selection Notes

Select this component when a standard 32.768 kHz frequency is required for timebase generation. The flat lead SMD package facilitates automated assembly processes. Consider the ±3 ppm/year aging rate for applications demanding long-term timekeeping accuracy without frequent calibration. Verify compatibility with the host microcontroller's internal or external oscillator circuitry.

Crystals Part Context

This part belongs to the family of precision crystals manufactured by YIC. These components are engineered to provide reliable frequency references for digital systems. The 32.768 kHz output is a standard choice for dividing down to one second intervals in binary counters. The specific model designation indicates the frequency, load capacitance, and package variant.

Crystals Replacement Considerations

Direct substitutes include other 32.768 kHz crystals with identical 12.5 pF load capacitance and compatible ESR values. Variants such as the 32.768K12.5PI/MC306 offer different package dimensions but similar electrical characteristics. Ensure any replacement maintains the same frequency tolerance and physical footprint constraints.
