Crystals Procurement Notes

Verify the specific suffix 'I' against official CTS documentation to confirm it denotes the intended frequency tolerance and stability class, as suffix variations may indicate different electrical specifications or packaging options. Confirm that the 18 pF load capacitance matches the target circuit design requirements before finalizing procurement orders to ensure system-level frequency accuracy.

Crystals Selection Notes

Select this component when a fundamental resonance crystal is required for 32.768 MHz applications with strict size constraints. The 4-SMD footprint allows for automated assembly processes. Ensure the application circuit can accommodate the specified 60 Ohm ESR limit. Consider the -40°C to +85°C operating range suitability for the intended environmental conditions compared to commercial grade alternatives.
