QT325S-26.000MEIV-T

Overview

The QT325S-26.000MEIV-T is a surface-mount quartz crystal resonator manufactured by QST, designed for precision timing applications. It operates at a fundamental frequency of 26 MHz with a load capacitance of 8 pF. The component exhibits a frequency stability of ±20 ppm over the operating temperature range and a frequency tolerance of ±10 ppm at 25°C. Physical dimensions are 3.2 x 2.5 x 0.7 mm in a 4-SMD, no-lead package.

Feature Summary

• Compact 3.2x2.5mm SMD footprint suitable for space-constrained designs
• High frequency stability of ±20 ppm across industrial temperature ranges
• Low profile 0.7mm height for standard surface mount processes

Applications

• Microcontroller clock sources
• Communication module timing references
• Portable electronic device oscillators

Procurement Notes

Verify the specific suffix MEIV-T against official QST documentation to confirm the ±20 ppm stability rating and 8 pF load capacitance. Ensure the requested quantity matches the manufacturer's standard packaging specifications. Confirm that the operating temperature range aligns with the system requirements before finalizing the order.

Selection Notes

Select this component when a 26 MHz reference with ±20 ppm stability is required in a compact 3.2x2.5mm package. Consider the 8 pF load capacitance compatibility with the host oscillator circuit. Evaluate thermal performance needs against the specified operating range to ensure reliable operation under environmental stress.

Part Context

This part belongs to the QT325S series of thin-mode quartz crystals from QST. The series offers various frequencies and stability grades within a standardized small outline package.
