QT532G-12.000MAAV-T

Overview

The QST QT532G-12.000MAAV-T is a surface-mount quartz crystal resonator operating at a fundamental frequency of 12 MHz. It features a frequency stability and tolerance of ±30ppm at 25°C, with an equivalent series resistance (ESR) of 50 Ohms. The component utilizes a load capacitance of 8pF and is housed in a compact 2-SMD, No Lead package measuring 5.00mm x 3.20mm x 1.20mm. It supports operation within a temperature range of -20°C to +70°C and complies with RoHS3 standards.

Feature Summary

• Fundamental mode oscillation for precise timing applications
• Compact 2-SMD no-lead footprint for automated assembly
• Stable frequency performance across specified industrial temperature ranges

Applications

• Microcontroller clock sources
• Communication module timing circuits
• Consumer electronics control boards

Procurement Notes

Verify the specific suffix MAAT against official QST documentation to confirm the 8pF load capacitance and -20°C to 70°C temperature range, as variations exist within the QT532G family. Ensure compatibility with target circuit design parameters before integration.

Selection Notes

Select this variant when an 8pF load capacitance is required for the oscillator circuit. Compare against the MAHJ variant which offers extended temperature support (-40°C to 85°C) but may differ in physical or electrical characteristics. Confirm package dimensions match PCB layout constraints.

Part Context

This component belongs to the QT532G series of general-purpose quartz crystals from QST. The series provides various frequency options and package sizes, with the 12.000MHz variant serving as a common clock reference for digital logic and embedded systems requiring moderate stability.

Replacement Considerations

Public confirmed substitutes include CTS-Frequency Controls part numbers 445I23D12M00000 and 445I33D12M00000, which are parameter-equivalent alternatives.
