QT216G-27.000MDDQ-T

Overview

The QT216G-27.000MDDQ-T is a surface-mount crystal oscillator manufactured by QST. It operates at a fundamental frequency of 27 MHz with a load capacitance of 10 pF. The component features a frequency stability of ±20 ppm at 25°C and across the operating temperature range of -20°C to +70°C. The resonator tolerance is specified at ±20 ppm. The physical package dimensions are 2.0 mm x 1.6 mm x 0.6 mm, designed for SMD mounting.

Feature Summary

• Compact 2.0x1.6x0.6 mm surface-mount package design
• High frequency stability of ±20 ppm over specified temperature range
• Optimized for 10 pF load capacitance applications

Applications

• Clock signal generation in embedded systems
• Wireless communication modules requiring 27 MHz reference
• Consumer electronics with space-constrained PCB layouts

Procurement Notes

Verify the specific suffix configuration against official QST documentation to ensure compatibility with required load capacitance and stability specifications. Confirm that the operating temperature range of -20°C to +70°C aligns with the target application environment. Cross-reference the package dimensions (2.0x1.6x0.6 mm) with the footprint design to prevent assembly errors during manufacturing.

Selection Notes

Select this component when a 27 MHz reference with ±20 ppm stability is required within a 2.0x1.6 mm footprint. Ensure the circuit design supports a 10 pF load capacitance to maintain frequency accuracy. Consider the -20°C to +70°C operating range for environmental suitability. Compare against other QST variants if tighter tolerance or extended temperature ranges are necessary.

Part Context

This part belongs to the QST crystal oscillator family, characterized by small form factors suitable for modern portable devices. The QT216G series typically offers stable performance for general-purpose clocking needs. Variants within this series may differ in frequency, tolerance, or temperature range while maintaining similar physical dimensions.
