Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct frequency tolerance and packaging specifications. Confirm that the requested variant matches the required load capacitance and ESR parameters for the target circuit design before finalizing procurement orders.

Crystals Selection Notes

Select this component when a standard 32.768 kHz reference is required for timekeeping functions. Ensure the application circuit supports the specified 12.5 pF load capacitance and can drive the high impedance of the 70 kOhm ESR characteristic effectively for reliable oscillation start-up.

Crystals Part Context

This part belongs to Meritek's line of passive timing components, specifically focusing on quartz crystals for precision frequency control. The MXT series typically addresses the demand for compact, reliable oscillators used in digital systems where accurate time division and synchronization are critical operational requirements.

Crystals Replacement Considerations

Cross-reference with other Meritek models such as MXTVBFI32K768 or MXT1BFI32K768 if different package styles or specific environmental ratings are required. Verify pin compatibility and electrical equivalence before substituting.
