QT532S-36.000MEEQ-T

Overview

The QT532S-36.000MEEQ-T is a quartz crystal resonator manufactured by QST Products LLC. It operates at a fundamental frequency of 36 MHz with a frequency tolerance of ±10 ppm. The component features a load capacitance of 10 pF and an equivalent series resistance (ESR) of 40 Ohms. It utilizes a surface-mount package measuring 5.0 x 3.2 x 0.9 mm with four solder pads. The device is designed for operation within a temperature range of -20°C to +70°C, ensuring stable performance in standard electronic applications.

Feature Summary

• Surface-mount quartz crystal resonator with no lead design
• High frequency stability of ±10 ppm across operating temperature
• Compact SMD footprint suitable for space-constrained PCB layouts

Applications

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

Procurement Notes

Verify the specific suffix EEQ against official QST documentation to confirm the exact temperature range and stability grade. Ensure the ordering part number matches the required 36 MHz frequency and 10pF load capacitance. Cross-reference the package dimensions with the target PCB footprint to guarantee mechanical compatibility during assembly.

Selection Notes

Select this component when a 36 MHz reference is required with ±10 ppm stability in a 5x3.2mm SMD package. Confirm that the system load capacitance aligns with the specified 10pF value to maintain accurate frequency output. Evaluate the -20°C to +70°C operating range against environmental conditions to ensure reliable operation without exceeding thermal limits.

Part Context

This part belongs to the QT532S family of quartz crystals from QST. Variants within this series offer different frequencies and stability grades, such as ±30 ppm or extended temperature ranges. The QT532S-36.000MEEQ-T specifically targets applications requiring precise timing at 36 MHz with moderate industrial temperature specifications.

Replacement Considerations

Direct substitutes include other 36 MHz crystals with identical 10pF load capacitance and 40 Ohm ESR in a 5032 package. Verify that alternative parts meet the same ±10 ppm stability requirement and compatible operating temperature range for seamless integration.
