QT161S-32.000MAHE-T

Overview

The QT161S-32.000MAHE-T is a fundamental mode quartz crystal resonator manufactured by QST, designed for surface-mount applications. It operates at a nominal frequency of 32 MHz with a load capacitance of 12 pF and an equivalent series resistance of 80 Ohms. The component exhibits a frequency stability of ±30 ppm at 25°C and ±30 ppm across the temperature range of -40°C to +85°C. The package dimensions are 1.60 mm x 1.20 mm x 0.35 mm in a 4-SMD, No Lead configuration.

Feature Summary

• Fundamental oscillation mode operation
• Surface-mount 4-SMD no lead package
• High frequency stability across industrial temperature ranges

Applications

• Microcontroller clock sources
• Communication module timing
• Digital signal processing circuits

Procurement Notes

Verify the specific suffix MAHE-T against official QST documentation to confirm the 12 pF load capacitance and ±30 ppm stability specifications. Ensure the ordering part number matches the required temperature range and package type. Cross-reference datasheets from authorized distributors to confirm active status and environmental compliance details before procurement.

Selection Notes

Select this component when a 32 MHz reference is required for space-constrained designs due to its compact 1.6x1.2 mm footprint. The 12 pF load capacitance suits circuits designed for standard capacitive loads. Consider the ±30 ppm tolerance for applications requiring moderate precision rather than high-stability oscillators.

Part Context

This part belongs to the QT161S series of quartz crystals from QST. The series offers various frequency options and stability grades within a standardized small outline package. The MAHE-T suffix denotes specific electrical characteristics including load capacitance and stability limits distinct from other variants like HV or EE.

Replacement Considerations

Direct substitutes must match the 32 MHz frequency, 12 pF load capacitance, and 4-SMD no lead package. Verify that alternative manufacturers provide equivalent ±30 ppm stability and similar ESR values to ensure circuit compatibility without redesign.
