QT161S-32.000MDDQ-T

Overview

The QT161S-32.000MDDQ-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 10 pF and an equivalent series resistance (ESR) of 80 Ohms. The component features a compact SMD package measuring 1.6 x 1.2 x 0.35 mm. Frequency stability is rated at ±20 ppm across both the 25°C reference temperature and the extended operating range of -20°C to +70°C.

Feature Summary

• Compact 4-SMD, no-lead surface mount package design
• High frequency stability within specified industrial temperature ranges
• Optimized electrical characteristics for standard oscillator circuits

Applications

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

Procurement Notes

Verify the specific manufacturer designation, as this part number is associated with QST in distributor catalogs but may appear under TXC branding in other contexts. Confirm the exact package dimensions and tolerance specifications against the official datasheet prior to integration. Ensure compatibility with the target PCB footprint and soldering profile requirements.

Selection Notes

Select this component when a 32 MHz reference is required for space-constrained designs. The 10 pF load capacitance and 80 Ohm ESR must match the oscillator circuit design parameters. Consider the ±20 ppm stability requirement relative to system timing accuracy needs and the -20°C to +70°C operating range suitability for the intended environment.

Part Context

This crystal belongs to the QT161S series of low-profile quartz resonators. The series offers various frequency options and stability grades tailored for consumer electronics and portable devices. The specific suffix indicates the frequency, tolerance, and packaging configuration unique to this variant.
