QT216S-26.000MAHJ-T

Overview

The QT216S-26.000MAHJ-T is a surface-mount crystal oscillator manufactured by TXC Corporation, marketed under the QST brand. It operates at a fundamental frequency of 26 MHz with a load capacitance of 18 pF. The component provides frequency stability of ±30 ppm over both initial tolerance and temperature range. It functions within an industrial temperature range of -40°C to +85°C and utilizes a compact 4-SMD, no-lead package measuring 2.0 x 1.6 mm.

Feature Summary

• Compact surface-mount design suitable for space-constrained PCB layouts
• Industrial-grade temperature operation ensuring reliability in varied environments
• High frequency stability for precise timing applications

Applications

• Microcontroller clock sources
• Communication module timing
• Consumer electronics timing circuits

Procurement Notes

Verify the manufacturer designation carefully, as this component is produced by TXC Corporation but distributed under the QST branding. Confirm the specific suffix 'MAHJ-T' matches the required load capacitance and stability specifications. Ensure the package dimensions align with the designated footprint on the target printed circuit board to guarantee proper assembly and electrical connection.

Selection Notes

Select this component when a 26 MHz reference signal is required for digital logic or communication interfaces. The ±30 ppm stability suits general-purpose timing needs rather than high-precision radio applications. Consider the 18 pF load capacitance requirement to ensure accurate oscillation frequency. Verify that the operating temperature range meets the environmental conditions of the final device deployment.

Part Context

This part belongs to the QT216S series of surface-mount crystals. These components are designed for general timing applications where small form factors are critical. The series offers various frequency options while maintaining consistent mechanical and electrical characteristics across the product line for standardized design integration.

Replacement Considerations

Direct substitutes include other 26 MHz SMD crystals with identical 18 pF load capacitance and ±30 ppm stability. Verify pin compatibility and thermal ratings before substitution.
