QT325G-24.000MAAV-T

Overview

The QT325G-24.000MAAV-T is a quartz crystal resonator manufactured by QST, operating at a fundamental frequency of 24 MHz. It features a surface-mount package with dimensions of 3.2 mm x 2.5 mm x 0.8 mm. The component exhibits a frequency tolerance and stability of ±30 ppm at 25°C and ±30 ppm over the -20°C to +70°C temperature range. It utilizes an 8 pF load capacitance and has a maximum equivalent series resistance (ESR) of 60 Ohms.

Feature Summary

• Glass seal technology for enhanced environmental stability
• Compact 4-SMD no-lead surface mount footprint
• Fundamental mode operation for precise timing applications

Applications

• Microcontroller clock sources
• Communication module timing references
• Consumer electronics oscillators

Procurement Notes

Verify the manufacturer designation on the official datasheet, as the QT325G series is commonly associated with TXC Corporation. Ensure the specific suffix matches the required load capacitance and temperature stability specifications. Confirm RoHS compliance status through the manufacturer's documentation before integration into regulated assemblies.

Selection Notes

Select this component when a 24 MHz fundamental frequency is required with tight ±30 ppm stability across commercial temperature ranges. The 8 pF load capacitance must match the oscillator circuit design. Consider the 60 Ohm ESR limit for power consumption constraints in low-power designs.

Part Context

This part belongs to the QT325G series of glass-sealed quartz crystals. Similar variants exist with different frequencies such as 16.384 MHz or 32 MHz, and varying load capacitances like 12 pF. The series is characterized by small form factors suitable for dense PCB layouts.

Replacement Considerations

The QT325G-24.000MAHV-T serves as a direct substitute within the same series, differing primarily in load capacitance specifications. Verify pin compatibility and electrical parameters against the original design requirements.
