QT325S-54.000MAAE-T

Overview

The QT325S-54.000MAAE-T is a surface-mount crystal resonator manufactured by QST Products, LLC. It operates at a nominal frequency of 54 MHz and utilizes a 12 pF load capacitance. The component exhibits a frequency stability of ±30 ppm across an operating temperature range of -20°C to +70°C. Physical dimensions are specified as 3.2 x 2.5 x 0.7 mm in a no-lead SMD package.

Feature Summary

• Surface-mount design for automated assembly
• High frequency stability within specified thermal limits
• Compact footprint suitable for space-constrained PCB layouts

Applications

• Clock generation for microprocessors
• Timing reference for communication modules
• Oscillator circuits in consumer electronics

Procurement Notes

Verify the manufacturer part number against official QST documentation to ensure compatibility with specific load capacitance requirements. Confirm that the operating temperature range meets the environmental specifications of the target application before procurement.

Selection Notes

Select this component when a 54 MHz timing source is required with moderate stability. Ensure the circuit design accommodates the 12 pF load capacitance. Verify that the -20°C to +70°C range aligns with the operational environment constraints.

Part Context

This model belongs to the QT325S series of surface-mount crystals from QST. The series offers various frequency options and stability grades, distinguished by suffix codes indicating tolerance and temperature ranges. This specific variant provides standard industrial stability.

Replacement Considerations

Substitute parts must match the 54 MHz frequency, 12 pF load capacitance, and 3.2x2.5mm package dimensions. Verify equivalent frequency stability and temperature range specifications from alternative manufacturers.
