QT216S-32.000METQ-T

Overview

The QT216S-32.000METQ-T is a surface-mount quartz crystal manufactured by QST Products, LLC. It operates at a fundamental frequency of 32 MHz with a load capacitance of 10 pF. The component provides high frequency stability of ±10 ppm at both 25°C and across the extended industrial temperature range of -30°C to +85°C. Housed in a compact 4-SMD no-lead package measuring 2.0 x 1.6 x 0.5 mm, it utilizes seam seal technology for reliable performance in precision timing applications.

Feature Summary

• Seam seal construction ensures robust environmental protection and long-term reliability
• High frequency stability maintained at ±10 ppm across the full operating temperature range
• Compact surface-mount design facilitates automated assembly and space-constrained layouts

Applications

• Precision clock generation for microcontrollers and digital signal processors
• Timing references for communication interfaces such as UART and SPI
• Frequency standards for portable consumer electronics and IoT devices

Procurement Notes

Verify the manufacturer designation carefully, as this specific part number is associated with TXC Corporation in some catalogs despite the brand query. Confirm the package dimensions and pin configuration against your PCB footprint requirements. Ensure the load capacitance matches your oscillator circuit design to achieve the specified frequency accuracy. Check current availability status as supply chain conditions may vary.

Selection Notes

Select this component when precise timing is required within a limited board area. The 10 pF load capacitance must align with the host circuit's specifications to prevent frequency deviation. Consider the -30°C to +85°C rating if the device will operate in variable thermal environments. The seam seal package offers superior durability compared to standard epoxy-sealed alternatives.

Part Context

This crystal belongs to the QT216S series, characterized by small form factor and high stability. Similar variants include the QT216S-32.000MEIQ-T which offers ±20 ppm stability, and the QT216S-32.000MEEV-T which uses an 8 pF load capacitance. These components share the same physical dimensions but differ in electrical tolerances and loading requirements.

Replacement Considerations

Direct substitutes include the QT216S-32.000MEIQ-T for relaxed tolerance needs or the QT216S-32.000MEEV-T if the circuit supports 8 pF loading. Verify that any replacement maintains the 32 MHz frequency and compatible package size to ensure mechanical fit.
