QT532G-18.432MAHJ-T

Overview

The QT532G-18.432MAHJ-T is a quartz crystal resonator from the QT532G series, manufactured by QST Products, LLC. It operates at a fundamental frequency of 18.432 MHz with a frequency tolerance and stability of ±30 ppm. The component features a load capacitance of 18 pF and an equivalent series resistance (ESR) of 50 Ohms. It is housed in a surface-mount device (SMD) package with dimensions of 5mm x 3.2mm and utilizes a no-lead construction.

Feature Summary

• Fundamental mode quartz crystal operation
• Surface-mount SMD package design
• No-lead construction for automated assembly

Applications

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

Procurement Notes

Verify manufacturer designation as QST Products, LLC or TXC Corporation depending on supply chain source. Confirm package marking and reel specifications match procurement requirements. Ensure RoHS compliance documentation is available for regulatory adherence. Validate lot traceability for quality control processes prior to production integration.

Selection Notes

Select this component when a 18.432 MHz reference is required with ±30 ppm stability. The 18 pF load capacitance must match the oscillator circuit design. The 50 Ohm ESR specification influences drive level considerations. The 5x3.2mm footprint dictates PCB layout constraints compared to smaller or larger crystal variants.

Part Context

This part belongs to the QT532G series of surface-mount crystals. Variants within this series differ primarily by frequency and load capacitance values while maintaining similar physical dimensions and electrical characteristics. The series supports various frequencies including 12.000 MHz and 20.000 MHz.

Replacement Considerations

QT532G-18.432MAAJ-T is a documented variant within the same series. Verify pin compatibility and electrical parameters before substitution. Other frequencies in the QT532G series are not electrically interchangeable.
