QT161S-26.000MAAB-T

Overview

The QST QT161S-26.000MAAB-T is a surface-mount crystal oscillator operating at a fundamental frequency of 26.000 MHz. It utilizes an AT-cut quartz resonator element housed in a compact 1612 (1.6mm x 1.2mm) SMD package. The device is designed for clock signal generation in portable electronic applications requiring stable frequency reference.

Feature Summary

• Compact surface-mount design suitable for space-constrained PCB layouts
• Fundamental mode operation for precise frequency stability
• AT-cut quartz construction for reliable temperature characteristics

Applications

• Mobile communication devices
• Portable consumer electronics
• Embedded system clock sources

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to ensure compatibility with required load capacitance and drive level specifications. Confirm that the package dimensions and terminal configuration match the target footprint design before finalizing procurement orders.

Selection Notes

Select this component when a 26 MHz fundamental frequency is required in a minimal footprint. Ensure the application circuit supports the specified load capacitance and that the drive level remains within safe operational limits to prevent frequency shifts or aging issues.

Part Context

This part belongs to QST's line of miniature surface-mount crystal oscillators. The QT161S series is engineered for high-volume manufacturing processes, offering consistent performance across production batches while maintaining strict tolerance standards for timing-critical digital systems.

Replacement Considerations

Direct substitutes must match the 1612 package outline, 26.000 MHz frequency, and fundamental mode operation. Verify equivalent electrical parameters such as load capacitance and stability before integrating alternative components into existing designs.
