QT216S-26.000MAAE-T

Overview

The QT216S-26.000MAAE-T is a quartz crystal oscillator manufactured by QST, designed for precision timing applications. It operates at a nominal frequency of 26 MHz with a frequency tolerance of ±30 ppm. The component features a load capacitance of 8 pF and an equivalent series resistance of 90 Ohms. It utilizes a 4-SMD, No Lead package configuration with dimensions of 2.00 mm x 1.60 mm. The device supports an operating temperature range from -20°C to +70°C, ensuring reliable performance in consumer electronics environments requiring stable clock signals.

Feature Summary

• Provides precise timing stability with ±30 ppm frequency tolerance
• Compact 4-SMD no-lead surface mount package design
• Optimized for low power consumption in portable devices

Applications

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

Procurement Notes

Verify the specific suffix 'AAE' against official QST documentation to confirm exact electrical parameters and packaging specifications. Ensure compatibility with existing PCB footprint designs and reflow soldering profiles. Cross-reference the load capacitance requirements with the target circuit design to maintain frequency accuracy within specified tolerances during procurement.

Selection Notes

Select this component when a 26 MHz reference signal with moderate stability is required for space-constrained designs. The ±30 ppm tolerance suits general-purpose timing rather than high-precision metrology. Consider the 8 pF load capacitance match with the host oscillator circuit. Evaluate the -20°C to +70°C range against environmental conditions before finalizing the selection.

Part Context

This part belongs to the QT216S series of surface-mount crystals from QST. The series offers various frequencies and tolerances within a standardized 2.0x1.6 mm form factor. This specific model targets applications needing a balance between size, cost, and timing accuracy, distinct from higher-stability or wider-temperature variants in the same product line.

Replacement Considerations

Direct substitutes must match the 26 MHz frequency, 4-SMD package, and similar electrical characteristics. Verify that alternative components meet the ±30 ppm tolerance and 8 pF load capacitance requirements to ensure circuit compatibility without redesign.
