Crystals Procurement Notes

Verify the specific load capacitance requirement against the target oscillator circuit design, as this component specifies 6 pF. Confirm that the 50 kOhm ESR aligns with the host controller's drive level specifications to prevent overdriving or failure to start. Ensure the surface-mount footprint matches the mechanical dimensions provided in the official datasheet.

Crystals Selection Notes

Select this component when a standard 32.768 kHz reference is required for battery-backed systems. The ±20 ppm tolerance suits general-purpose timing where high precision is not critical. Consider the 6 pF load capacitance compatibility with the MCU's internal capacitors before finalizing the design.
