QT216S-16.000MEIV-T

Overview

The QT216S-16.000MEIV-T is a quartz crystal resonator manufactured by QST, operating at a fundamental frequency of 16.000 MHz. It features an 8 pF load capacitance and utilizes a surface-mount SMD package with dimensions of 2.0 mm x 1.6 mm. The component exhibits a frequency tolerance of ±10 ppm at 25°C and ±20 ppm across the industrial temperature range of -40°C to +85°C. It has a maximum equivalent series resistance (ESR) of 120 Ohms and employs a seam seal construction for environmental protection.

Feature Summary

• Seam seal construction provides enhanced environmental stability
• Compact 2.0x1.6 mm surface-mount footprint facilitates dense PCB layouts
• High frequency stability supports precision timing requirements in embedded systems

Applications

• Embedded communication modules requiring stable clock signals
• Microcontroller system clocks within automotive or industrial environments
• Consumer electronics utilizing compact surface-mount designs

Procurement Notes

Verify the specific suffix configuration against official QST documentation to ensure compatibility with target circuit load capacitance and temperature specifications. Confirm that the seam seal technology aligns with the required environmental durability standards for the intended application environment before finalizing procurement decisions.

Selection Notes

Select this component when a 16 MHz reference signal is required with tight initial tolerance and moderate temperature stability. The 2.0x1.6 mm size is suitable for space-constrained designs. Ensure the host oscillator circuit is designed to accommodate the 120 Ohm ESR limit and 8 pF load capacitance for optimal performance.

Part Context

This part belongs to the QT216S series of quartz crystals from QST, characterized by small form factors and robust sealing methods. The series targets applications demanding reliable frequency generation in limited spaces. The 16.000 MHz variant specifically serves as a standard clock source for digital logic and communication interfaces.

Replacement Considerations

Direct substitutes must match the 16 MHz frequency, 8 pF load capacitance, 2.0x1.6 mm package, and ±20 ppm temperature stability. Verify ESR limits and sealing type compatibility with existing board designs.
