QT252S-26.000MAAE-T

Overview

The QT252S-26.000MAAE-T is a surface-mount quartz crystal manufactured by QST, designed for precise frequency control in electronic circuits. It operates at a nominal frequency of 26 MHz and utilizes a 4-SMD, no-lead package with dimensions of 2.5x2.0x0.55 mm. The component features a load capacitance of 12 pF and offers a frequency stability of ±30 ppm at 25°C and ±30 ppm over the temperature range of -20°C to +70°C. This device is RoHS compliant and lead-free, ensuring environmental safety standards are met.

Feature Summary

• Seam seal construction for reliable operation
• Surface mount design for automated assembly
• RoHS compliant and lead-free manufacturing

Applications

• Clock signal generation for microcontrollers
• Frequency reference for communication modules
• Timing source for digital logic circuits

Procurement Notes

Verify that the specific suffix 'AAE' corresponds to the required 12 pF load capacitance and the -20°C to +70°C temperature stability range. Confirm package compatibility with PCB footprint specifications. Ensure compliance with RoHS directives if applicable to the target market. Cross-reference manufacturer documentation for exact electrical parameters before integration.

Selection Notes

Select this component when a 26 MHz frequency reference is required with moderate stability. The 12 pF load capacitance must match the oscillator circuit design. Consider the operating temperature range limits. Verify package dimensions against available board space. Ensure the application does not require tighter stability than ±30 ppm.

Part Context

This part belongs to the QT252S series of surface-mount quartz crystals from QST. The series provides various frequency options within a compact 2.5x2.0 mm footprint. Different suffixes indicate variations in load capacitance and temperature stability ranges. This specific model targets applications requiring standard stability at a common clock frequency.

Replacement Considerations

Compatible substitutes include other 26 MHz SMD crystals with identical 2.5x2.0 mm dimensions, 12 pF load capacitance, and ±30 ppm stability. Verify pinout compatibility and thermal characteristics. Check manufacturer datasheets for equivalent performance metrics.
