QT216S-26.000MAAJ-T

Overview

The QT216S-26.000MAAJ-T is a quartz crystal resonator manufactured by QST, operating at a fundamental frequency of 26 MHz. It features a load capacitance of 18 pF and an equivalent series resistance (ESR) of 90 Ohms. The component exhibits a frequency tolerance of ±30 ppm at 25°C and ±30 ppm over the operating temperature range of -20°C to +70°C. It utilizes a 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Seam-sealed ceramic construction for environmental stability
• Fundamental mode operation for precise timing applications
• Compact surface-mount form factor suitable for space-constrained designs

Applications

• Microcontroller clock sources
• Communication module timing references
• Consumer electronics oscillators

Procurement Notes

Verify manufacturer authenticity through authorized distributors. Confirm specific suffix designations match required temperature ranges and load capacitance values. Request batch-specific test reports to ensure compliance with stated frequency tolerances and ESR specifications prior to integration.

Selection Notes

Select this component when a 26 MHz fundamental frequency is required within a 2.0x1.6mm footprint. Ensure the system load capacitance matches the 18pF specification to maintain accuracy. Verify that the -20°C to +70°C operating range aligns with the target application's thermal environment.

Part Context

This part belongs to the QT216S series of surface-mount crystals. It shares the same physical dimensions and general electrical characteristics with variants such as QT216S-26.000MAAV-T and QT216S-26.000MAHJ-T, differing primarily in manufacturer origin and specific temperature grade certifications.

Replacement Considerations

Direct substitutes include TXC Corporation parts like QT216S-26.000MAHJ-T or QST variants such as QT216S-26.000MAAV-T. Cross-referencing requires verification of identical load capacitance, ESR, and temperature range specifications.
