Crystals Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature grade compliance against the manufacturer's official datasheet. Confirm that the 4-SMD footprint matches the PCB land pattern dimensions exactly. Ensure circuit loading capacitors align with the 13pF specification to maintain frequency accuracy within the stated tolerance limits during final assembly validation.

Crystals Selection Notes

Select this component when a 32.768 MHz fundamental frequency is required in a compact SMD form factor. The industrial temperature rating supports operation in wider thermal environments compared to commercial grades. Consider the 60 Ohm ESR value for oscillator circuit compatibility and startup reliability. Verify that the 13pF load capacitance requirement matches the host system's oscillator design constraints.
