QT252S-48.000MAHE-T

Overview

The QT252S-48.000MAHE-T is a quartz crystal resonator manufactured by QST, designed for surface-mount applications. It features a 2.5x2.0 mm seam seal package with four pads and ceramic construction. The device operates at a fundamental frequency of 48.000 MHz with a load capacitance of 12 pF. Frequency tolerance and stability are specified at ±30 ppm at 25°C and ±30 ppm across the -40 to 85°C temperature range. This component provides precise timing solutions for electronic circuits requiring stable clock signals within industrial operating conditions.

Feature Summary

• Seam seal construction ensures environmental protection and mechanical durability
• Compact surface-mount footprint facilitates automated assembly processes
• Stable frequency performance maintained across wide industrial temperature ranges

Applications

• Industrial control systems requiring precise timing references
• Communication equipment utilizing 48 MHz clock signals
• Microcontroller-based embedded systems needing stable oscillators

Procurement Notes

Verify the manufacturer designation carefully, as listings may attribute this part to TXC Corporation or QST due to historical brand transitions. Confirm the specific suffix MAHE-T matches the required load capacitance and tolerance specifications. Ensure the datasheet aligns with the intended application requirements before finalizing procurement decisions.

Selection Notes

Select this component when a 48 MHz fundamental frequency is required in a small surface-mount package. Consider the ±30 ppm stability requirement against system timing constraints. Evaluate the 12 pF load capacitance compatibility with the host oscillator circuit design to ensure accurate frequency operation without external trimming.

Part Context

This part belongs to the QT252S series of quartz crystals, characterized by their 2.5x2.0 mm dimensions. The series offers various frequency options while maintaining consistent package geometry and electrical characteristics. The MAHE-T suffix indicates specific tolerance and packaging attributes within this product family line.

Replacement Considerations

Direct substitutes include other manufacturers' 48 MHz crystals in 2520 packages with identical ±30 ppm stability and 12 pF load capacitance. Verify pin compatibility and mounting pad dimensions to ensure seamless integration into existing PCB layouts without redesigning the footprint.
