QT216S-32.000MEIQ-T

Overview

The QT216S-32.000MEIQ-T is a surface-mount quartz crystal oscillator manufactured by QST, designed for precise frequency generation in electronic circuits. It operates at a nominal frequency of 32 MHz and utilizes a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 x 0.5 mm. The component features a load capacitance of 10 pF and offers a frequency tolerance of ±10 ppm at 25°C. It maintains a frequency stability of ±20 ppm across the extended industrial temperature range of -40°C to +85°C, ensuring reliable performance in demanding environments.

Feature Summary

• Compact 2.0x1.6mm surface-mount package suitable for space-constrained designs
• High frequency stability of ±20ppm over the full industrial temperature range
• Seam-seal construction providing robust environmental protection
• Optimized for moderate-precision timing applications

Applications

• Embedded communication systems requiring stable clock signals
• Motor control cabinets and industrial automation equipment
• Avionics and navigation systems in aerospace applications
• Radar and defense communication hardware

Procurement Notes

Verify the complete part number including suffixes such as 'T' for tape-and-reel packaging when ordering. Confirm that the specific frequency tolerance and stability requirements align with your system design before procurement. Ensure compatibility with standard SMD reflow soldering profiles. Check for any specific handling instructions regarding electrostatic discharge sensitivity during storage and assembly processes.

Selection Notes

Select this component when a 32 MHz reference signal is required with strict stability constraints in harsh thermal conditions. The ±20ppm stability over -40°C to +85°C makes it superior to commercial-grade alternatives for industrial use. Consider the small footprint if board real estate is limited. Evaluate the 10pF load capacitance against your microcontroller or oscillator circuit specifications to ensure proper oscillation.

Part Context

This part belongs to the QT216S series of seam-seal quartz crystals from QST. The series includes various frequencies such as 16 MHz, 24 MHz, and 96 MHz, all sharing similar physical dimensions and mounting characteristics. The MEIQ suffix typically denotes specific tolerance and stability grades within the product line, distinguishing it from other variants with different performance metrics or packaging options.

Replacement Considerations

Direct substitutes include the QT216S-32.000METQ-T and QT216S-24.000MEIQ-T from TXC Corporation, which share identical mechanical dimensions and similar electrical characteristics. Verify that replacement parts maintain the same ±10ppm/±20ppm stability profile and 10pF load capacitance to ensure circuit compatibility without redesign.
