QT161S-26.000MAAC-T

Overview

The QT161S-26.000MAAC-T is a surface-mount quartz crystal manufactured by QST, operating at a nominal frequency of 26 MHz. It features a compact Seam Seal package with dimensions of 1.6 x 1.2 x 0.35 mm. The component provides a load capacitance of 6 pF and maintains a frequency tolerance of ±30 ppm at 25°C. It ensures stability within ±30 ppm across an industrial temperature range of -20°C to +70°C. The device utilizes a four-pad ceramic construction for reliable SMD mounting.

Feature Summary

• Seam seal ceramic construction for robust surface-mount integration
• Industrial-grade thermal stability across specified temperature ranges
• Compact footprint suitable for space-constrained circuit designs

Applications

• Digital signal processing controller clock sources
• Motor control system timing references
• Industrial automation equipment oscillators

Procurement Notes

Verify the manufacturer designation carefully, as the QT161S series appears in catalogs under both TXC Corporation and QST branding. Confirm that the specific suffix MAAC-T aligns with the required 26 MHz frequency and 6 pF load capacitance specifications. Ensure the requested units meet RoHS compliance standards and verify the package orientation matches the design layout before finalizing orders.

Selection Notes

Select this component when a 26 MHz reference is required for industrial applications demanding ±30 ppm stability between -20°C and +70°C. The 6 pF load capacitance must match the oscillator circuit requirements. Consider the 1.6 x 1.2 mm body size for board space optimization. Validate that the Seam Seal technology meets the environmental protection needs of the target deployment scenario.

Part Context

This part belongs to the QT161S series of surface-mount quartz crystals. The series offers various frequency options and stability grades within a standardized small outline package. These components are designed to replace through-hole crystals in modern PCB layouts, providing improved mechanical reliability and automated assembly compatibility for high-volume manufacturing processes.

Replacement Considerations

Direct substitutes include other 26 MHz SMD crystals with identical 1.6x1.2mm dimensions and 6pF load capacitance. Verify that alternative parts maintain the same ±30 ppm stability over the -20°C to +70°C range. Check for equivalent Seam Seal construction to ensure comparable moisture resistance and mechanical durability during reflow soldering.
