Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the ESR value of 100 Ohms matches circuit requirements. Ensure the ±30 ppm stability rating meets system timing accuracy needs. Check manufacturer documentation for RoHS compliance status prior to final procurement decisions.

Selection Notes

Select this component for applications requiring precise 13.56 MHz timing in compact spaces. The 3.2x2.5 mm footprint suits dense PCB layouts. Consider the 100 Ohm ESR for oscillator circuit compatibility. Evaluate the -40°C to +85°C operating range against environmental conditions.

Part Context

This part belongs to the QT325G series of SMD crystals from QST. The series offers various frequency options within the same physical package. The MAHE suffix denotes specific electrical characteristics including load capacitance and stability grades. This model represents a standard industrial-grade option.

Replacement Considerations

Direct substitutes must match the 13.56 MHz frequency, 12 pF load capacitance, and 3.2x2.5 mm package. Verify ESR compatibility with existing oscillator designs. Cross-reference stability ratings across the full temperature range before substitution.
