QT161S-26.000MDDY-T

Overview

The QT161S-26.000MDDY-T is a surface-mount crystal oscillator manufactured by QST, operating at a nominal frequency of 26 MHz. It features a compact 1.6x1.2 mm package with a maximum height of 0.40 mm. The component exhibits a frequency tolerance and stability of ±20 ppm across the industrial temperature range of -20°C to +70°C. It utilizes a load capacitance of 7 pF and is supplied in tape-and-reel packaging for automated assembly processes.

Feature Summary

• Compact 1.6x1.2 mm surface-mount footprint suitable for space-constrained designs
• Stable frequency performance within ±20 ppm tolerance over specified temperature ranges
• Designed for high-volume automated placement via standard tape-and-reel delivery

Applications

• High-power motor control cabinets requiring stable timing references
• Industrial embedded systems needing precise clock signals
• Consumer electronics utilizing surface-mount crystal technology

Procurement Notes

Verify the specific suffix 'MDDY' against official QST documentation to confirm the exact frequency tolerance and temperature range specifications. Ensure the ordering quantity aligns with standard reel sizes provided by distributors. Cross-reference the manufacturer part number with authorized supply channels to guarantee authenticity and traceability of the components received.

Selection Notes

Select this component when a 26 MHz reference is required in a minimal footprint form factor. The ±20 ppm stability suits applications where moderate frequency accuracy is sufficient. Consider the -20°C to +70°C operating range to ensure compatibility with the target environment's thermal conditions during system design.

Part Context

This part belongs to the QT161S series of surface-mount crystals from QST. The series offers various frequency options and tolerance grades, identified by unique alphanumeric suffixes. These components are designed to replace through-hole equivalents in modern PCB layouts, providing reliability and ease of integration into automated manufacturing lines.

Replacement Considerations

Direct substitutes include other 26 MHz SMD crystals with identical 1.6x1.2 mm dimensions and ±20 ppm tolerance. Verify pin compatibility and electrical parameters before substitution. Alternative packages may require layout modifications.
