QT325G-27.000MEIV-T

Overview

The QT325G-27.000MEIV-T is a surface-mount quartz crystal oscillator manufactured by QST Products, LLC. It operates at a fundamental frequency of 27.000 MHz and utilizes a glass-sealed package design for enhanced stability. The component features a load capacitance of 8 pF and is housed in an SMD3225-4P footprint with dimensions of 3.20mm x 2.50mm. It offers a normal temperature frequency tolerance of ±10ppm and supports an operating temperature range of -40°C to +85°C.

Feature Summary

• Glass-sealed construction for improved environmental stability
• Surface-mount compatibility with standard SMD3225-4P footprint
• Wide operating temperature range supporting industrial applications

Applications

• General-purpose clock generation in electronic circuits
• Industrial control systems requiring stable timing references
• Consumer electronics utilizing surface-mount assembly processes

Procurement Notes

Verify the specific suffix 'MEIV' against official QST documentation to confirm the exact temperature range and tolerance specifications. Ensure the required load capacitance matches the circuit design requirements before procurement. Cross-reference the package dimensions with PCB layout constraints to guarantee proper fitment during assembly.

Selection Notes

Select this component when a 27 MHz reference signal is required with high stability over varying temperatures. The glass-seal technology provides superior performance compared to standard epoxy-sealed crystals. Consider the 8pF load capacitance requirement to ensure accurate frequency operation within the target application circuit.

Part Context

This part belongs to the QT325G series of quartz crystals from QST Products. The series is characterized by its compact 3.2x2.5mm size and robust glass-sealing method. Variations within the series differ primarily in frequency, tolerance codes, and temperature ranges, allowing for flexible integration into various timing-sensitive designs.

Replacement Considerations

Direct substitutes must match the 27.000 MHz frequency, 8pF load capacitance, and SMD3225-4P package. Verify that alternative components support the -40°C to +85°C operating range and ±10ppm tolerance. Glass-sealed variants are preferred for equivalent reliability.
