QT161S-32.000MEEV-T

Overview

The QT161S-32.000MEEV-T is a surface-mount quartz crystal manufactured by TXC Corporation, distributed by QST. It operates at a nominal frequency of 32 MHz with a fundamental oscillation mode. The component features an 8 pF load capacitance and maintains a frequency tolerance and stability of ±10 ppm at 25°C, extending to ±10 ppm across the -20°C to +70°C operating temperature range. It utilizes a 4-SMD, no-lead package with dimensions of 1.6 mm x 1.2 mm and a maximum height of 0.40 mm. The unit exhibits an equivalent series resistance (ESR) of 80 Ohms and supports RoHS3 compliance.

Feature Summary

• Seam-sealed ceramic construction for environmental protection
• High accuracy frequency stability across industrial temperature ranges
• Compact surface-mount footprint suitable for space-constrained designs

Applications

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

Procurement Notes

Verify the manufacturer designation on official documentation, as this part is produced by TXC Corporation and distributed under the QST catalog. Confirm that the specific ordering suffix matches the required load capacitance and tolerance specifications. Ensure compliance with RoHS3 standards and check moisture sensitivity level requirements for proper handling during assembly processes.

Selection Notes

Select this component when a 32 MHz fundamental mode crystal is required with strict ±10 ppm stability constraints in industrial environments. The 8 pF load capacitance must match the oscillator circuit design. Consider the 4-SMD no-lead package dimensions for PCB layout compatibility. Verify that the 80 Ohm ESR value aligns with the driving circuit capabilities to ensure reliable startup and operation.

Part Context

This component belongs to the QT161S series of high-accuracy MHz quartz crystals from TXC Corporation. These parts are designed for applications requiring precise timing in compact form factors. The series offers various frequency options within the same physical package, allowing for standardized board layouts across different product variants while maintaining consistent electrical performance characteristics.

Replacement Considerations

Direct substitutes include the 8Q-32.000MEEV-T from TXC Corporation, which shares identical electrical parameters and package dimensions. Other compatible alternatives may include crystals from Abracon LLC with matching 32 MHz frequency, 8 pF load capacitance, and similar SMD packaging constraints.
