QT532S-16.000MEEQ-T

Overview

The QT532S-16.000MEEQ-T is a surface-mount quartz crystal resonator manufactured by QST, operating at a nominal frequency of 16 MHz. It features a frequency tolerance and stability of ±10ppm, with a load capacitance of 10pF and an equivalent series resistance (ESR) of 40 Ohms. The component utilizes fundamental mode operation and is housed in a compact 4-SMD, No Lead package measuring 5.0mm x 3.2mm x 1.05mm. It supports a wide operating temperature range from -20°C to +70°C and complies with RoHS3 standards.

Feature Summary

• Compact 4-terminal SMD footprint for efficient PCB layout
• High frequency stability of ±10ppm across the operating temperature range
• Fundamental mode oscillation for precise timing applications
• RoHS3 compliant construction for environmental safety

Applications

• Microcontroller clock sources

• Consumer electronics timing control

Procurement Notes

Verify the specific suffix 'MEEQ-T' against official QST documentation to confirm pin configuration and termination type. Ensure the selected variant matches the required 4-SMD no-lead package dimensions and thermal characteristics for your assembly process.

Selection Notes

Select this component when a 16 MHz reference with ±10ppm stability is required in a small 5x3.2mm footprint. Consider the 40 Ohm ESR and 10pF load capacitance to ensure compatibility with the host oscillator circuit's design parameters.

Part Context

This part belongs to the QT532S series of quartz crystals from QST. The series offers various frequencies and stability grades in standardized SMD packages, providing designers with flexible options for timing applications requiring reliable performance in consumer and industrial devices.

Replacement Considerations

Direct substitutes must match the 16 MHz frequency, ±10ppm stability, 10pF load capacitance, and 4-SMD 5x3.2mm package. Verify ESR values and temperature ranges before substitution.
