QT325S-12.000MAAE-T

Overview

The QT325S-12.000MAAE-T is a surface-mount quartz crystal manufactured by QST. It operates at a fundamental frequency of 12 MHz with a load capacitance of 12 pF. The component exhibits a frequency stability of ±30 ppm at 25°C and ±30 ppm across the operating temperature range of -20°C to +70°C. It utilizes a seam seal package with dimensions of 3.2 mm x 2.5 mm x 0.7 mm, featuring four solder pads for reliable surface mounting.

Feature Summary

• Seam seal construction for enhanced environmental protection
• Fundamental mode operation at 12 MHz
• Compact 4-pad SMD footprint

Applications

• Embedded communication systems
• Microcontroller clock sources
• Consumer electronics timing circuits

Procurement Notes

Verify the specific suffix AAE-T against official QST documentation to confirm the -20°C to +70°C temperature rating and 12pF load capacitance. Ensure the selected variant matches the required thermal profile for the target application environment before finalizing procurement.

Selection Notes

Select this component when a 12 MHz reference is required in a compact 3.2x2.5mm package. Consider the ±30ppm stability limit and the -20°C to +70°C operational range during design. Verify compatibility with the system's load capacitance requirements.

Part Context
