QT216S-16.000MEIQ-T

Overview

The QT216S-16.000MEIQ-T is a surface-mount crystal oscillator manufactured by QST, designed for precision timing applications in electronic circuits. It operates at a fundamental frequency of 16.000 MHz and utilizes a compact 2.0x1.6 mm SMD package with a height of approximately 0.5 mm. The component exhibits a frequency stability of ±10 ppm at 25°C and ±20 ppm across the industrial temperature range of -40°C to +85°C. It features a load capacitance of 10 pF and is RoHS compliant, ensuring lead-free construction suitable for modern manufacturing processes.

Feature Summary

• Compact 2.0x1.6 mm surface-mount footprint for space-constrained designs
• High frequency stability of ±10 ppm at room temperature
• Industrial-grade temperature range from -40°C to +85°C
• Lead-free and RoHS compliant construction

Applications

• Avionics systems requiring precise clock signals
• Navigation and radar system timing components
• Communication equipment synchronization
• Embedded communication modules

Procurement Notes

Verify that the ordering suffix matches the required specifications, as variations may exist within the QT216S series. Confirm the specific load capacitance and stability requirements against the application design before procurement. Ensure the supplier provides documentation confirming RoHS compliance and lead-free status. Cross-reference part numbers carefully to avoid confusion with similar models having different frequency or package characteristics.

Selection Notes

Select this component when a small form factor is critical alongside high-frequency accuracy. The ±10 ppm stability at 25°C makes it suitable for applications sensitive to drift. Consider the -40°C to +85°C range for industrial environments. Compare ESR and load capacitance requirements with the host circuit's oscillator design to ensure proper startup and oscillation conditions are met.

Part Context

This part belongs to the QT216S series of surface-mount crystals from QST. The series offers various frequencies and stability options within a standardized 2.0x1.6 mm package. Similar parts include the QT216S-32.000METQ-T and QT216G-25.000MDDB-T, which share the same physical dimensions but differ in frequency and potentially stability ratings.

Replacement Considerations

Direct substitutes may include other 16 MHz crystals in a 2.0x1.6 mm package with ±10 ppm stability. Verify compatibility regarding load capacitance (10 pF) and operating temperature range. Check equivalent parts from other manufacturers offering identical electrical parameters and mechanical dimensions.
