QT49S-24.000MAGE-T

Overview

The QT49S-24.000MAGE-T is a 24 MHz fundamental mode quartz crystal resonator manufactured by QST. It operates within a temperature range of -20°C to +70°C and utilizes an HC-49/US surface-mount package with dimensions of 11.40mm x 4.80mm x 4.10mm maximum height. The component features a load capacitance of 12pF, an equivalent series resistance (ESR) of 30Ω, a frequency tolerance of ±30ppm at room temperature, and a frequency stability of ±50ppm.

Feature Summary

• Fundamental oscillation mode operation for precise timing applications
• Surface-mount HC-49/US package design for automated assembly
• Low equivalent series resistance of 30Ω for efficient circuit drive
• RoHS compliant construction supporting environmental regulations

Applications

• Microcontroller clock generation circuits
• Communication interface timing references

Procurement Notes

Verify the specific suffix MAGE against official QST documentation to confirm exact electrical tolerances and packaging specifications. Ensure the required load capacitance matches the target circuit design. Confirm that the operating temperature range meets the application environment requirements before finalizing procurement decisions.

Selection Notes

Select this component when a 24 MHz fundamental frequency is required in a surface-mount format. The 12pF load capacitance must align with the oscillator circuit design. Consider the ±30ppm tolerance for precision timing needs. Evaluate the HC-49/US footprint compatibility with the printed circuit board layout constraints.

Part Context

This part belongs to the QT49S series of quartz crystals from QST. The series offers various frequencies and package options. The HC-49/US form factor is widely used in electronic designs requiring reliable frequency control. This specific model provides a balance of performance and size for modern digital applications.

Replacement Considerations

QT49S-24.000MAHJ-T is a parameter-equivalent alternative with 18pF load capacitance. Verify circuit compatibility due to the difference in load capacitance values between the original and substitute parts.
