QT161S-26.000MAAV-T

Overview

The QT161S-26.000MAAV-T is a surface-mount quartz crystal oscillator manufactured by QST, part of the QT161S series. It operates at a fundamental frequency of 26 MHz with a load capacitance of 8 pF. The component exhibits a frequency stability and tolerance of ±30 ppm across its operating range. It features a compact 4-SMD, no-lead package with body dimensions of 1.6 x 1.2 x 0.35 mm. The device is designed for high-reliability applications requiring precise timing signals in space-constrained electronic systems.

Feature Summary

• Compact 4-SMD no-lead surface mount package
• High frequency stability of ±30 ppm
• Fundamental mode quartz resonator operation
• Designed for automated assembly processes

Applications

• FPGA signal processing setups
• Automotive control systems
• Microcontroller clock sources
• Communication interface timing

Procurement Notes

Verify the manufacturer designation carefully, as the QT161S series is primarily associated with TXC Corporation. Confirm that the specific suffix AAV-T corresponds to the requested 8 pF load capacitance and ±30 ppm stability from the official QST or authorized distributor datasheets. Ensure the component status is active before finalizing procurement plans.

Selection Notes

Select this component when a 26 MHz reference is required in ultra-compact designs. The 1.6 x 1.2 mm footprint allows for dense PCB layouts. Consider the ±30 ppm tolerance against system timing requirements. Verify compatibility with reflow soldering profiles specified in the manufacturing guidelines.

Part Context

This crystal belongs to the QT161S family, characterized by small outline dimensions suitable for portable electronics. Similar variants exist with different frequencies such as 24 MHz or 48 MHz, sharing the same mechanical envelope. The series supports standard SMD mounting techniques for efficient production integration.

Replacement Considerations

Direct substitutes include other 26 MHz crystals in identical 1.6x1.2mm packages with matching 8pF load capacitance. Cross-reference electrical parameters strictly. Verify pinout compatibility if alternative manufacturers are considered.
