QT325S-32.000MEEQ-T

Overview

The QT325S-32.000MEEQ-T is a quartz crystal resonator manufactured by TXC Corporation, distributed under the QST brand. It operates at a nominal frequency of 32 MHz with a load capacitance of 10 pF and an equivalent series resistance (ESR) of 50 Ohms. The component features a frequency tolerance of ±10 ppm and utilizes a 4-SMD, no-lead package measuring 3.2 mm x 2.5 mm x 0.7 mm. It supports surface mount technology and functions within a temperature range of -20°C to +70°C.

Feature Summary

• Seam seal construction utilizing ceramic materials for enhanced environmental stability
• Four-terminal surface mount design optimized for automated assembly processes
• Low equivalent series resistance ensuring efficient signal transmission

Applications

• Clock generation circuits in digital communication systems
• Timing references for microcontroller-based embedded devices
• Frequency control in consumer electronics requiring stable oscillation

Procurement Notes

Verify that the supplier provides official documentation from TXC Corporation or authorized distributors. Confirm the part number suffix matches the specific tolerance and packaging requirements. Ensure compliance with RoHS standards as indicated in the product specifications. Cross-reference the manufacturer's datasheet to validate electrical parameters before integration into designs.

Selection Notes

Select this component when a 32 MHz reference is required with ±10 ppm stability. The 10 pF load capacitance must match the oscillator circuit design. Consider the 50 Ohm ESR for drive level compatibility. The compact 3.2x2.5 mm package suits space-constrained PCB layouts. Verify the operating temperature range meets the application's environmental demands.

Part Context

This part belongs to the QT325S series of seam seal crystals. The series offers various frequencies and tolerances. The 32.000M variant provides a standard clock frequency. The MEEQ-T suffix indicates specific tolerance and tape-and-reel packaging. This series is designed for high-volume surface mount applications.

Replacement Considerations

Compatible substitutes include other 32 MHz crystals with identical 10 pF load capacitance and similar physical dimensions. Ensure replacement parts maintain the same ±10 ppm tolerance and 50 Ohm ESR. Verify that alternative components support the same SMD footprint and soldering profile.
