QT325G-30.000MAGJ-T

Overview

The QT325G-30.000MAGJ-T is a quartz crystal resonator manufactured by QST Products, LLC. It operates at a nominal frequency of 30 MHz with a load capacitance of 18 pF and an equivalent series resistance (ESR) of 60 Ohms. The component features a ±30 ppm frequency stability at 25°C and ±50 ppm over the temperature range of -40°C to +85°C. It utilizes a glass-sealed package with dimensions of 3.2mm x 2.5mm x 0.8mm in a 4-SMD, no-lead configuration.

Feature Summary

• Glass-sealed construction for environmental protection
• Surface-mount design for automated assembly
• Stable frequency performance across industrial temperature ranges

Applications

• Clock signal generation in microcontroller systems
• Timing references for communication interfaces
• Frequency control in consumer electronic devices

Procurement Notes

Verify the specific suffix codes against official QST documentation to ensure correct tolerance and temperature range specifications. Confirm package compatibility with PCB footprint requirements before ordering. Request manufacturer datasheets for detailed electrical characteristics and reliability data to validate suitability for the intended application environment.

Selection Notes

Select this component when a 30 MHz clock source is required with moderate stability requirements. Ensure the system load capacitance matches the specified 18 pF value to maintain accurate frequency operation. Consider the ±50 ppm total frequency tolerance over the full operating temperature range during circuit design.

Part Context

This part belongs to the QT325G series of surface-mount quartz crystals from QST. The series offers various frequency options and stability grades within a compact 3.2x2.5mm footprint. The MAGJ-T suffix indicates specific stability and packaging attributes defined by the manufacturer's coding system.

Replacement Considerations

Direct substitutes must match the 30 MHz frequency, 18 pF load capacitance, 60 Ohm ESR, and 3.2x2.5x0.8mm package dimensions. Verify that alternative components meet the same ±30 ppm @25°C and ±50 ppm (-40°C to +85°C) stability specifications.
