QT532S-24.000MAHJ-T

Overview

The QT532S-24.000MAHJ-T is a surface-mount quartz crystal resonator manufactured by QST, designed for precise frequency control in electronic circuits. It operates at a nominal frequency of 24 MHz with a fundamental oscillation mode. The component features a frequency stability and tolerance of ±30 ppm at both 25°C and the extended temperature range of -40°C to +85°C. It utilizes an 18 pF load capacitance and exhibits an equivalent series resistance (ESR) of 40 Ohms. The device is housed in a compact 4-SMD, No Lead package with dimensions of 5.0 mm x 3.2 mm x 0.9 mm, suitable for automated assembly processes.

Feature Summary

• Seam-sealed glass construction ensures long-term frequency stability and environmental robustness.
• Fundamental mode operation provides accurate timing signals at 24 MHz.
• Compact 4-SMD no-lead package facilitates efficient surface-mount placement.

Applications

• Microcontroller clock sources
• Communication module timing references
• Digital signal processing circuit synchronization

Procurement Notes

Verify the specific suffix 'MAHJ-T' against official QST documentation to confirm package type and sealing method. Ensure the required load capacitance matches the target oscillator circuit design. Confirm that the ±30 ppm stability specification meets the system's timing accuracy requirements across the full operating temperature range.

Selection Notes

Select this component when a 24 MHz fundamental frequency is required with high stability over industrial temperatures. Compare ESR values with the host oscillator circuit capabilities to ensure reliable startup. Consider the 4-SMD form factor for space-constrained PCB layouts requiring lead-free compliance.

Part Context

This part belongs to the QT532S series of seam-sealed quartz crystals from QST. It shares the same physical footprint as other variants in the family but differs in frequency and electrical parameters. The series is characterized by hermetic sealing for enhanced durability compared to ceramic-packaged alternatives.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Verify compatibility with direct replacements based on identical frequency, load capacitance, ESR, and package dimensions.
