Crystals Procurement Notes

Verify the specific suffix 'MDBQ' against the official TXC datasheet to confirm the exact tolerance, stability, and packaging configuration. Ensure the ordering quantity matches the manufacturer's reel specifications. Confirm RoHS compliance status directly from the product documentation prior to procurement to meet regulatory requirements.

Crystals Selection Notes

Select this component when a 28.224 MHz reference is required for automotive or wide-temperature environments. The 10 pF load capacitance must match the oscillator circuit design. Consider the 80 Ohm ESR limit for driver compatibility. The AEC-Q200 certification makes it suitable for applications demanding high reliability under thermal stress.

Crystals Part Context

This part belongs to the AX series of glass sealing crystals from TXC Corporation. These components are engineered for general-purpose timing applications where size and stability are balanced. The series supports various frequencies and packages, with the MDBQ variant specifically addressing automotive-grade stability requirements.

Crystals Replacement Considerations

Direct substitutes include other AEC-Q200 qualified 28.224 MHz crystals with identical 10 pF load capacitance and similar dimensional constraints. Verify that alternative parts maintain the same 50 ppm total stability and 80 Ohm ESR limits to ensure circuit performance equivalence.
