QT161S-32.000MAHV-T

Overview

The QT161S-32.000MAHV-T is a quartz crystal resonator manufactured by QST, designed for surface-mount applications. It operates at a fundamental frequency of 32 MHz with a load capacitance of 8 pF and an equivalent series resistance of 80 Ohms. The component utilizes a 4-SMD, no-lead package with dimensions of 1.6 x 1.2 x 0.35 mm. Frequency stability is rated at ±30 ppm at 25°C and ±30 ppm over the operating temperature range of -40°C to +85°C.

Feature Summary

• Seam seal construction for enhanced environmental protection
• Compact 4-SMD no-lead surface mount design
• High frequency stability across wide industrial temperature ranges

Applications

• Microcontroller clock sources
• Communication module timing circuits
• Industrial control system oscillators

Procurement Notes

Verify the manufacturer designation on the datasheet, as the model prefix may appear under QST or TXC Corporation depending on the specific production batch. Confirm that the suffix HV corresponds to the required ±30 ppm stability specification for both room temperature and the extended -40°C to +85°C range. Ensure the 8 pF load capacitance matches the oscillator circuit requirements before integration.

Selection Notes

Select this component when a small footprint is critical for high-frequency signal generation. The 32 MHz output suits digital logic timing needs. Verify that the 80 Ohm ESR is compatible with the driving circuit's power constraints. The wide temperature stability makes it suitable for harsh environments where standard commercial-grade crystals might fail.

Part Context

This part belongs to the QT161S family of seam-seal crystals. Variants in this series differ primarily in frequency, load capacitance, and temperature stability codes. The QT161S form factor provides a robust alternative to larger through-hole crystals while maintaining precise timing accuracy for modern compact electronic designs.

Replacement Considerations

Direct substitutes include other 32 MHz crystals with identical 1.6x1.2mm dimensions and 8pF load capacitance. Ensure replacement parts maintain the ±30 ppm stability at -40°C to +85°C. Cross-reference pinout compatibility for 4-SMD no-lead packages to guarantee correct soldering alignment.
