QT325G-37.050MAGV-T

Overview

The QST QT325G-37.050MAGV-T is a surface-mount quartz crystal resonator with a nominal frequency of 37.05 MHz. It features a 4-SMD, no-lead package measuring 3.20mm x 2.50mm with a maximum seated height of 0.90mm. The component exhibits a frequency tolerance of ±30ppm and a frequency stability of ±50ppm over the operating temperature range of -40°C to +85°C. It utilizes an 8pF load capacitance and has a specified equivalent series resistance of 60 Ohms.

Feature Summary

• Surface mount design for automated assembly
• High stability across wide industrial temperature ranges
• Compact footprint suitable for space-constrained PCB layouts

Applications

• Clock generation for microcontrollers
• Communication module timing circuits
• Embedded system oscillator references

Procurement Notes

Verify the complete part number including suffixes against manufacturer datasheets to ensure correct frequency tolerance and temperature range specifications. Confirm package dimensions and soldering profile requirements prior to integration. Ensure supply chain authenticity through authorized channels to prevent counterfeit components.

Selection Notes

Select this component when a 37.05 MHz reference is required with ±50ppm stability in harsh thermal environments. Consider the 8pF load capacitance compatibility with the host oscillator circuit. Evaluate the 4-SMD no-lead package constraints against available board real estate and reflow soldering capabilities.

Part Context

This model belongs to the QT325G series of thin-film bulk acoustic resonator (FBAR) or similar advanced crystal technologies from QST. The series offers various frequency options and stability grades, distinguished by alphanumeric suffixes indicating tolerance and temperature performance characteristics.

Replacement Considerations

Direct substitutes include other QT325G variants with identical 37.05 MHz frequency but different stability ratings, such as those with ±30ppm or ±10ppm specifications, provided the application tolerates tighter limits. Cross-brand replacements require matching frequency, load capacitance, and ESR values.
