QT325S-48.000MAAE-T

Overview

The QST QT325S-48.000MAAE-T is a quartz crystal resonator designed for surface-mount applications. It operates at a fundamental frequency of 48 MHz with a load capacitance of 12 pF. The component exhibits a frequency stability of ±30 ppm at 25°C and maintains the same tolerance across an industrial temperature range of -20°C to +70°C. Physical dimensions are 3.2 x 2.5 x 0.7 mm in a four-pad seam seal package.

Feature Summary

• Seam seal construction for environmental protection
• Industrial temperature range operation
• Surface-mount compatible design

Applications

• Microcontroller clock sources
• Communication module timing
• Digital signal processing circuits

Procurement Notes

Verify the specific suffix 'AAE' against the manufacturer's current datasheet to confirm pin configuration and soldering profile requirements. Ensure the load capacitance matches the oscillator circuit design. Confirm availability status as inventory levels fluctuate rapidly for standard SMD components.

Selection Notes

Select this component when a 48 MHz reference is required in compact PCB layouts. The ±30 ppm stability suits general digital logic applications. Consider thermal performance if operating near the upper temperature limit. Verify impedance matching with the host oscillator driver.

Part Context

This part belongs to the QT325S series, characterized by small footprint quartz crystals. The series offers various frequencies while maintaining consistent mechanical dimensions. It serves as a direct replacement for legacy through-hole crystals in modern miniaturized electronics designs requiring precise timing references.
