QT325G-26.000MEEQ-T

Overview

The QT325G-26.000MEEQ-T is a quartz crystal resonator manufactured by QST, operating at a fundamental frequency of 26 MHz. It features a compact surface-mount package measuring 3.2 mm in length, 2.5 mm in width, and 0.7 mm in height. The component exhibits a frequency tolerance and stability of ±10 ppm at 25°C and across the operating range of -20°C to +70°C. It utilizes a load capacitance of 10 pF and has an equivalent series resistance (ESR) of 60 Ohms. The device is designed for SMD/SMT mounting and is supplied in tape and reel packaging.

Feature Summary

• Glass-sealed construction for enhanced environmental durability
• Compact 3.2mm x 2.5mm surface-mount footprint
• High frequency stability with ±10 ppm tolerance

Applications

• Clock signal generation for microprocessors
• Timing references for communication modules
• Oscillator circuits in consumer electronics

Procurement Notes

Verify the manufacturer designation carefully, as distribution listings may attribute this part to TXC Corporation due to historical acquisitions or cross-listing practices. Confirm that the specific suffix 'MEEQ' corresponds to the glass-sealed variant with the specified 10pF load capacitance and 60 Ohm ESR parameters before finalizing procurement orders.

Selection Notes

Select this component when a 26 MHz fundamental frequency crystal is required for space-constrained designs. Ensure the application circuit supports a 10 pF load capacitance to maintain the specified ±10 ppm stability. Consider the -20°C to +70°C operating temperature range against the environmental conditions of the end product.

Part Context

This part belongs to the QT325G series of quartz crystals from QST. The series is characterized by small form factors suitable for modern portable devices. The 26 MHz frequency is commonly used in wireless applications and legacy interface timing.

Replacement Considerations

The 7M-26.000MEEQ-T from TXC Corporation is a documented substitute with identical electrical specifications including 26 MHz frequency, 10 pF load capacitance, and 10 ppm stability.
