QT532G-24.576MAAE-T

Overview

The QT532G-24.576MAAE-T is a quartz crystal resonator manufactured by QST, designed for surface-mount applications. It operates at a fundamental frequency of 24.576 MHz with a frequency stability and tolerance of ±30ppm. The component features a load capacitance of 12pF and an equivalent series resistance (ESR) of 50 Ohms. It utilizes a 2-SMD, no lead package with dimensions of 5.00mm x 3.20mm and a maximum height of 1.35mm. The device supports base harmonic operation and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Surface-mount quartz crystal resonator optimized for precision timing circuits
• Fundamental mode operation ensuring stable frequency generation at 24.576 MHz
• Robust performance across industrial temperature ranges from -40°C to +85°C

Applications

• Precision timing circuits requiring stable clock signals
• Microcontroller and processor clock sources
• Communication equipment frequency references

Procurement Notes

Verify the specific suffix 'AAE' against datasheets to confirm package type and pin configuration. Ensure the manufacturer is identified as QST rather than TXC, as similar part numbers exist across brands. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process before procurement.

Selection Notes

Select this component when a 24.576 MHz fundamental frequency is required with ±30ppm stability. The 12pF load capacitance must match the oscillator circuit design. Consider the 50 Ohm ESR limit for drive level constraints. The 2-SMD footprint requires adequate PCB space for 5.00mm x 3.20mm dimensions.

Part Context

This part belongs to the QT532G series of quartz crystals from QST. It serves as a direct electrical substitute for the discontinued TXC 7A-24.576MAHE-T, maintaining identical frequency and electrical parameters. The QT532G series offers alternative sourcing options for designs previously reliant on TXC components.

Replacement Considerations

QT532G-24.576MAHE-T is a confirmed substitute with identical electrical specifications but a different package outline. Verify mechanical fitment before replacement.
