• Digital signal processing circuits requiring precise timing

Procurement Notes

Verify the part number suffix HE-T against official QST documentation to confirm the specific package variant and tape-and-reel packaging details. Ensure that the required load capacitance matches the circuit design specifications. Confirm RoHS compliance status through the manufacturer's current certification documents before integration into regulated products.

Selection Notes

Select this component when a 24.576 MHz reference is required for digital systems. The ±30 ppm stability suits general-purpose timing applications. Consider the 12 pF load capacitance requirement for circuit matching. The 4-SMD no lead package is suitable for automated surface mount assembly processes.

Part Context

This part belongs to the QT325G series of quartz crystals from QST Products. The series offers various frequencies in a standardized 3.2x2.5 mm footprint. The MAHE-T suffix indicates specific electrical parameters and packaging options within the product line.

Replacement Considerations

Direct substitutes must match the 24.576 MHz frequency, 12 pF load capacitance, and 4-SMD no lead package. Verify ESR limits and temperature stability requirements. Cross-reference with other manufacturers offering similar SMD crystal packages.
