QT325S-24.000MEEQ-T

Overview

The QT325S-24.000MEEQ-T is a quartz crystal oscillator manufactured by TXC Corporation, distributed under the QST brand designation. It operates at a nominal frequency of 24 MHz with a load capacitance of 10 pF and an equivalent series resistance of 50 Ohms. The component utilizes a surface-mount package measuring 3.2 mm x 2.5 mm with a glass seal construction. Frequency stability is specified at ±10 ppm at 25°C and ±20 ppm across the -40°C to 85°C operating temperature range.

Feature Summary

• Glass-sealed surface-mount construction for environmental protection
• High frequency stability within specified industrial temperature ranges
• Compact footprint suitable for space-constrained circuit designs

Applications

• Microcontroller clock sources
• Communication module timing references
• Digital signal processing circuits

Procurement Notes

Verify manufacturer origin as TXC Corporation despite QST distribution labeling. Confirm package dimensions and pin configuration match design requirements. Validate frequency tolerance and temperature range specifications against application needs. Ensure compatibility with reflow soldering profiles recommended for glass-sealed components.

Selection Notes

Select this component when a 24 MHz reference is required in a 3.2x2.5 mm SMD package. Consider the ±10 ppm stability requirement at room temperature and ±20 ppm over the extended temperature range. Verify that the 10 pF load capacitance matches the host circuit's design parameters before integration.
