Procurement Notes

Verify the complete part number including suffixes against official QST documentation to ensure correct frequency, tolerance, and package configuration. Confirm RoHS compliance status and specific load capacitance requirements match the target circuit design before procurement. Cross-reference datasheet specifications for ESR and drive level limits.

Selection Notes

Select this component when a 26 MHz fundamental mode crystal with ±30 ppm stability is required. Ensure the application circuit provides the specified 12 pF load capacitance. Verify that the 60 Ohm maximum ESR aligns with the oscillator circuit's driving capability. Confirm the 4-SMD footprint matches the PCB layout constraints.

Part Context

This part belongs to the QT325G series of SMD crystals from QST. The series offers various frequencies and tolerances in standardized small footprints. The MAHE suffix typically denotes specific stability and package variations within the product line. This model represents a standard industrial-grade option for general-purpose timing needs.

Replacement Considerations

Direct substitutes must match the 26 MHz frequency, 12 pF load capacitance, 60 Ohm ESR, and 4-SMD 3.2x2.5mm package. Verify pin compatibility and mounting orientation. Check if alternative manufacturers offer identical electrical parameters and thermal ratings for seamless integration.
