QT216S-54.000METV-T

Overview

The QT216S-54.000METV-T is a fundamental-mode quartz crystal resonator manufactured by QST Products, LLC. It operates at a nominal frequency of 54 MHz and utilizes a 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. The component exhibits a frequency stability of ±10 ppm over an operating temperature range of -30°C to +85°C. It features a load capacitance of 8 pF and is designed for surface-mount applications requiring compact footprints.

Feature Summary

• Compact 2.0 x 1.6 mm surface-mount footprint suitable for space-constrained designs
• Fundamental-mode operation providing stable oscillation at 54 MHz
• Tight frequency stability of ±10 ppm across industrial temperature ranges

Applications

• High-frequency clock generation in mobile communication devices
• Timing reference for microcontrollers and digital signal processors
• Wireless module synchronization circuits

Procurement Notes

Verify the specific load capacitance and equivalent series resistance values against the official QST datasheet prior to integration. Confirm that the 4-SMD no-lead package compatibility matches the target PCB soldering profile. Ensure the ±10 ppm stability specification meets the system timing requirements for the intended operating temperature range.

Selection Notes

Select this component when a 54 MHz fundamental-mode crystal is required in a minimal 2.0 x 1.6 mm SMD package. It is appropriate for designs needing ±10 ppm stability within the -30°C to +85°C range. Consider the 8 pF load capacitance requirement for circuit matching. This part is suitable for applications prioritizing size reduction without compromising frequency precision.

Part Context

This model belongs to the QT216S series of miniature quartz crystals from QST. The series is characterized by small form factors and high reliability for consumer electronics. The METV suffix typically denotes specific tolerance and temperature characteristics consistent with the 10 ppm / -30 to +85°C specification found in public documentation for similar variants.

Replacement Considerations

Direct substitutes must match the 54 MHz frequency, 4-SMD 2.0x1.6mm package, and ±10 ppm stability. Verify load capacitance compatibility. Cross-reference with other manufacturers offering identical fundamental-mode crystals in the same footprint.
