QT325S-32.000MAHV-T

Overview

The QT325S-32.000MAHV-T is a surface-mount quartz crystal resonator manufactured by QST, designed for precision timing applications. It operates at a fundamental frequency of 32 MHz with a frequency tolerance of ±30 ppm at 25°C and ±60 ppm over the extended temperature range of -40°C to +85°C. The component features an 8 pF load capacitance and a maximum equivalent series resistance (ESR) of 50 Ohms. It utilizes a 4-SMD, no-lead package with body dimensions of 3.2 mm x 2.5 mm x 0.7 mm, suitable for automated assembly processes in compact electronic designs.

Feature Summary

• Seam-sealed metal housing provides robust environmental protection and long-term stability.
• Low profile SMD form factor enables high-density PCB layout and automated placement.
• Stable frequency performance across industrial temperature ranges ensures reliable clock signals.

Applications

• Microcontroller clock sources
• Communication interface modules
• Digital signal processing circuits

Procurement Notes

Verify the complete part number including suffixes to ensure correct frequency tolerance and packaging specifications. Confirm that the supplier source is authorized to guarantee component authenticity and traceability. Check datasheet revisions for any updates regarding mechanical footprints or electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when a 32 MHz reference is required for space-constrained designs. Ensure the circuit load capacitance matches the specified 8 pF to maintain accuracy. Verify that the operating environment falls within the -40°C to +85°C range and that the ±30 ppm initial tolerance meets system jitter requirements.

Part Context

This model belongs to the QT325S series of seam-sealed crystals from QST. The series offers various frequencies and tolerances in a standardized 3.2x2.5 mm footprint. It serves as a direct replacement for other industry-standard 32 MHz crystals in similar packages, providing consistent performance for timing-critical digital systems.

Replacement Considerations

Compatible substitutes include QT325S-32.000MAKV-T from QST, which shares identical electrical parameters and physical dimensions. Other manufacturers offering 32 MHz crystals in 3.2x2.5 mm SMD packages may be considered if pin compatibility and load capacitance match exactly.
