QT161S-26.000MEEB-T

Overview

The QT161S-26.000MEEB-T is a surface-mount quartz crystal oscillator manufactured by QST, operating at a nominal frequency of 26 MHz. It features a compact 4-SMD, no-lead package with dimensions of 1.6 x 1.2 x 0.35 mm. The component exhibits a load capacitance of 6 pF and maintains a frequency stability of ±10 ppm at 25°C and ±10 ppm across the industrial temperature range of -20°C to +70°C.

Feature Summary

• Seam-sealed ceramic construction for environmental protection
• Surface-mount design suitable for automated assembly
• High frequency stability within specified temperature ranges

Applications

• Clock signal generation in microprocessor systems
• Timing reference for communication interfaces
• Frequency control in consumer electronic devices

Procurement Notes

Verify the manufacturer marking on the component body matches QST specifications. Confirm the suffix EEB-T corresponds to the required ±10 ppm stability and 6 pF load capacitance. Ensure the package dimensions align with the PCB footprint requirements. Check RoHS compliance documentation if restricted substances are prohibited in the application environment.

Selection Notes

Select this component when a 26 MHz timing source is required in a space-constrained design. The 6 pF load capacitance must match the oscillator circuit requirements. Consider the ±10 ppm stability sufficient for standard digital logic applications. Verify that the -20°C to +70°C operating range meets the environmental conditions of the final product.

Part Context

This part belongs to the QT161S series of thin-film or bulk acoustic wave crystals designed for high-volume surface-mount production. The series offers various frequency options and stability grades, with the QT161S model specifically engineered for cost-effective integration in portable and industrial electronics requiring precise timing.

Replacement Considerations

Direct substitutes include other manufacturers' 26 MHz SMD crystals with identical 1.6x1.2mm footprints, 6pF load capacitance, and ±10 ppm stability. Verify pin compatibility and thermal characteristics before substitution.
