QT161S-26.000MEEI-T

Overview

The QST QT161S-26.000MEEI-T is a surface-mount quartz crystal resonator operating at a fundamental frequency of 26 MHz. It features a compact 4-SMD, no-lead package with dimensions of 1.6 mm x 1.2 mm x 0.35 mm. The component utilizes a load capacitance of 16 pF and provides a frequency tolerance of ±10 ppm. Frequency stability is maintained within ±10 ppm across an operating temperature range of -20°C to +70°C.

Feature Summary

• Compact surface-mount design suitable for space-constrained PCB layouts
• Stable frequency output with precise load capacitance integration
• Reliable performance within specified industrial temperature ranges

Applications

• Clock signal generation in microcontroller circuits
• Timing references for communication interfaces
• Frequency control in consumer electronic devices

Procurement Notes

Verify the specific suffix code against official QST documentation to confirm exact electrical characteristics and temperature stability ratings. Ensure the ordering part number matches the required load capacitance and frequency tolerance specifications for the target application circuit design.

Selection Notes

Select this component when a small footprint is required alongside standard 26 MHz timing needs. Confirm that the system oscillator circuit supports the 16 pF load capacitance requirement. Validate that the operational environment remains within the -20°C to +70°C range to maintain the specified ±10 ppm stability.

Part Context

This model belongs to the QT161S series of surface-mount crystals from QST. The series offers various frequency options and package sizes. The MEEI suffix denotes specific stability and temperature performance parameters distinct from other variants in the same physical package family.

Replacement Considerations

Direct substitutes must match the 26 MHz frequency, 16 pF load capacitance, and 1.6x1.2x0.35mm package dimensions. Verify equivalent stability ratings of ±10 ppm over the -20°C to +70°C range before implementation.
