Procurement Notes

Verify the specific suffix MEIE-T against official QST documentation to confirm the ±10ppm stability rating and 12pF load capacitance specifications. Ensure the requested part matches the required temperature range and mounting type before procurement, as suffix variations define critical electrical parameters.

Selection Notes

Select this component when a 26MHz fundamental frequency is required in a small footprint. Consider the ±10ppm stability requirement relative to system tolerance needs. Verify compatibility with the target circuit's load capacitance requirements and ensure the operating temperature range meets environmental constraints.

Part Context

This part belongs to the QT325S series of surface-mount crystals from QST Products. The series provides various frequency options in a standardized 3.2x2.5x0.7mm package. Different suffixes indicate variations in stability, temperature range, and load capacitance, allowing designers to select components tailored to specific timing precision requirements.

Replacement Considerations

Cross-reference other QST QT325S variants with matching 26MHz frequency and compatible load capacitance. Verify that alternative suppliers offer equivalent fundamental mode crystals with similar physical dimensions and stability ratings to ensure functional interchangeability.
