QT325G-11.0592MAHV-T

Overview

The QT325G-11.0592MAHV-T is a MHz quartz crystal manufactured by QST, designed for timing applications. It features a 3.2x2.5 mm glass seal package and operates at a nominal frequency of 11.0592 MHz. The component exhibits a frequency tolerance and stability of ±30 ppm within the specified temperature range. It utilizes an 8 pF load capacitance and has a maximum equivalent series resistance (ESR) of 150 Ohms. The device is available in a 4-SMD, no lead configuration, ensuring compatibility with surface-mount assembly processes.

Feature Summary

• Glass-sealed construction for environmental protection
• Surface-mount compatible 4-SMD no lead package
• Stable frequency output for precision timing circuits

Applications

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

Procurement Notes

Verify the specific suffix HV against official QST documentation to confirm exact tolerance and temperature range specifications. Ensure the load capacitance requirement matches the target circuit design. Confirm package dimensions align with PCB footprint constraints. Cross-reference the manufacturer part number to avoid confusion with similar variants in the QT325G series.

Selection Notes

Select this component when a compact 3.2x2.5 mm form factor is required for space-constrained designs. The 11.0592 MHz frequency is suitable for baud rate generation in serial communications. Consider the ±30 ppm stability for general-purpose timing where high precision is not critical. Evaluate the 150 Ohm ESR limit against oscillator circuit requirements.

Part Context

This part belongs to the QT325G series of quartz crystals from QST. The series offers various frequency options and package sizes. The QT325G designation indicates a specific size and style within the product line. Other variants may differ in frequency, tolerance, or load capacitance while sharing the same physical package.

Replacement Considerations

Direct substitutes must match the 11.0592 MHz frequency, 8 pF load capacitance, and 3.2x2.5 mm glass seal package. Verify that alternative components meet the ±30 ppm stability and 150 Ohm ESR specifications. Check pinout compatibility for the 4-SMD no lead configuration.
