Crystals Procurement Notes

Verify that the specific suffix matches the required load capacitance and tolerance specifications for your circuit design. Confirm the package dimensions align with your PCB land pattern requirements. Ensure the supplier provides valid RoHS compliance documentation. Check for AEC-Q200 qualification if the application involves automotive standards. Validate the manufacturing date code against project timelines.

Crystals Selection Notes

Select this component when a small form factor is critical alongside strict frequency stability requirements. The 26 MHz output suits applications needing precise timing without the complexity of active oscillators. Consider the 12 pF load capacitance compatibility with your oscillator circuit. Evaluate the ESR value against your driver circuit capabilities. The glass seal technology offers superior moisture resistance compared to standard epoxy packages.

Crystals Part Context

This part belongs to the TXC 7R series of miniature quartz crystals. The series is characterized by its glass-sealed hermetic structure, which distinguishes it from standard epoxy-sealed counterparts. These components are engineered for high-reliability applications where environmental exposure could compromise standard crystal performance. The 26 MHz frequency is a common choice for microcontroller clocks and communication interfaces.

Crystals Replacement Considerations

The 7R-26.000MEEC-T is listed as a similar alternative within the same manufacturer portfolio. Verify if the MEEC variant meets the specific load capacitance and tolerance needs of the current design. Cross-reference the pinout and mechanical dimensions to ensure physical compatibility on the existing PCB layout.
