QT161S-32.000MAHQ-T

Overview

The QT161S-32.000MAHQ-T is a 32 MHz quartz crystal resonator manufactured by QST. It features a frequency tolerance of ±30 ppm at 25°C and ±30 ppm across the operating temperature range of -40°C to +85°C. The component utilizes a 10 pF load capacitance and exhibits an equivalent series resistance (ESR) of 80 Ohms. It is housed in a compact 4-SMD, no lead package with dimensions of 1.6 mm x 1.2 mm.

Feature Summary

• Provides stable 32 MHz oscillation for timing circuits
• Designed for surface-mount assembly processes
• Operates reliably within industrial temperature ranges

Applications

• Microcontroller clock sources
• Communication module timing references
• Digital signal processing systems

Procurement Notes

Verify the specific suffix HQ against official QST documentation to confirm exact stability and packaging specifications. Ensure compatibility with reflow soldering profiles defined in the datasheet. Confirm that the 10 pF load capacitance matches the oscillator circuit design requirements before integration into the final product assembly.

Selection Notes

Select this component when a 32 MHz reference with ±30 ppm stability is required for space-constrained designs. The 1.6x1.2 mm footprint suits high-density PCB layouts. Consider the 80 Ohm ESR value for oscillator driver strength calculations. This part is suitable for applications requiring consistent performance across standard industrial temperature conditions.

Part Context

This crystal belongs to the QT161S series from QST, which offers various frequency options in a standardized small outline package. The series supports general-purpose timing needs in consumer and industrial electronics. The MAHQ variant specifically denotes the 32 MHz frequency point with associated stability and packaging characteristics defined by the manufacturer.

Replacement Considerations

Direct substitutes include other 32 MHz crystals with identical 1.6x1.2 mm SMD footprints and 10 pF load capacitance. Verify that alternative parts meet the same ±30 ppm stability and 80 Ohm ESR specifications. Check for compatible operating temperature ranges and mounting reliability standards before substitution.
