QT532S-36.000MBBK-T

Overview

The QT532S-36.000MBBK-T is a quartz crystal resonator manufactured by QST, designed for surface-mount applications. It operates at a fundamental frequency of 36 MHz with a standard load capacitance of 20 pF and a maximum series resistance of 80 Ohms. The component features a frequency tolerance of ±50 ppm at 25°C and maintains stability within ±50 ppm across an operating temperature range of -20°C to +70°C. It is housed in a compact 4-SMD, No Lead package with dimensions of 5.0 x 3.2 x 0.9 mm, ensuring compatibility with automated assembly processes.

Feature Summary

• Surface-mount quartz crystal design for high-frequency signal generation
• Compact 4-SMD no-lead package suitable for space-constrained PCB layouts
• Stable frequency performance across defined industrial temperature ranges

Applications

• Clock source for microcontrollers and digital logic circuits
• Frequency reference for communication modules
• Timing components in consumer electronics devices

Procurement Notes

Verify the specific suffix BBT against official QST documentation to confirm exact tolerance and temperature specifications. Ensure the ordering part number matches the required load capacitance and package type. Cross-reference the manufacturer's latest datasheet to validate RoHS compliance status and recommended soldering profiles before integration into production designs.

Selection Notes

Select this component when a 36 MHz surface-mount crystal with ±50 ppm tolerance is required. Consider the 20 pF load capacitance requirement for circuit matching. Evaluate the 80 Ohm maximum ESR against oscillator driver strength. Confirm that the -20°C to +70°C temperature range meets the operational environment requirements of the target application.

Part Context

This part belongs to the QT532S family of surface-mount crystals from QST. The model designation indicates a 36 MHz frequency variant with specific tolerance and packaging characteristics. Similar parts in the series offer different frequencies or tighter tolerances, such as the MAHJ or MEEQ suffixes, which may provide improved stability or different load capacitance options for specialized timing applications.

Replacement Considerations

Direct substitutes include other 36 MHz SMD crystals with identical 20 pF load capacitance and compatible package dimensions. Verify equivalent electrical parameters such as ESR and frequency stability before substitution. Parts like the QT532S-36.000MEEQ-T offer tighter tolerance but require verification of functional equivalence.
