QT325G-24.576MAAV-T

Overview

The QT325G-24.576MAAV-T is a surface-mount quartz crystal resonator manufactured by QST. It operates at a fundamental frequency of 24.576 MHz with a load capacitance of 8 pF. The component features a 3.2 x 2.5 mm SMD package and exhibits a frequency tolerance of ±30 ppm at 25°C, maintaining stability within the same range from -20°C to +70°C.

Feature Summary

• Utilizes a compact 3.2 x 2.5 mm surface-mount footprint for space-constrained designs
• Provides stable oscillation with ±30 ppm frequency tolerance across specified temperature ranges
• Designed for low-power applications with an 8 pF load capacitance requirement

Applications

• Microcontroller clock sources
• Communication module timing circuits
• Portable electronic device synchronization

Procurement Notes

Verify the manufacturer designation carefully, as this part number appears in catalogs associated with both QST and TXC Corporation. Confirm the specific datasheet version and electrical parameters directly with the supplier to ensure alignment with design requirements before procurement.

Selection Notes

Select this component when a small form factor is required alongside moderate frequency stability. Ensure the target circuit provides the necessary 8 pF load capacitance to achieve the specified ±30 ppm accuracy. Consider thermal environment constraints relative to the -20°C to +70°C operating range.

Part Context

This crystal belongs to the QT325G series, characterized by its glass-sealed or ceramic construction suitable for general-purpose timing applications. It serves as a passive frequency-determining element in oscillator circuits, replacing older through-hole variants with modern surface-mount capabilities.

Replacement Considerations

Direct substitutes include the QT325G-24.576MAHV-T and QT325G-24.576MAAQ-T from the same manufacturer family. Verify pin compatibility and load capacitance specifications when cross-referencing with other 325G series variants.
