QT325G-24.576MAGV-T

Overview

The QT325G-24.576MAGV-T is a quartz crystal resonator manufactured by QST, designed for surface-mount applications. It operates at a nominal frequency of 24.576 MHz with a load capacitance of 8 pF and an equivalent series resistance of 60 Ohms. The component features a glass-sealed package with dimensions of 3.20mm x 2.50mm (0.126" L x 0.098" W). Frequency tolerance is specified at ±30 ppm within the -20°C to +70°C range, while stability extends to ±50 ppm across the wider industrial temperature range of -40°C to +85°C.

Feature Summary

• Glass-sealed construction for enhanced environmental protection
• Compact 3.2x2.5 mm surface-mount footprint
• High frequency stability across industrial temperature ranges

Applications

• Wireless networking modules
• Embedded system clock sources
• Microcontroller oscillator circuits

Procurement Notes

Verify the specific suffix code against official QST documentation to confirm temperature stability ratings and tolerance levels. Ensure the selected variant matches the required operating environment, as different suffixes denote distinct performance characteristics regarding frequency drift over temperature. Cross-reference the datasheet for precise electrical parameters before integration.

Selection Notes

Select this component when a stable 24.576 MHz reference is required in space-constrained designs. The glass-seal technology offers reliability advantages over standard epoxy packages. Consider the ±30 ppm tolerance for precision timing needs or the ±50 ppm rating for broader industrial applications. Confirm compatibility with the target circuit's load capacitance requirements.

Part Context

This part belongs to the QT325G series of surface-mount crystals from QST. The series utilizes a 3.2x2.5 mm package size, balancing miniaturization with performance. Variants within the series differ primarily in frequency tolerance and temperature stability specifications, allowing designers to choose based on application sensitivity.

Replacement Considerations

Direct substitutes include other 24.576 MHz crystals in 3225 packages with matching 8pF load capacitance. Verify that alternative parts meet the same ±30 ppm or ±50 ppm stability requirements depending on the original design intent.
