QT532G-16.000MAHJ-T

Overview

The QT532G-16.000MAHJ-T is a quartz crystal resonator from the QT532G series manufactured by QST. It operates at a fundamental frequency of 16 MHz with a frequency tolerance and stability of ±30 ppm across operating temperatures ranging from -40°C to +85°C. The component features a load capacitance of 18 pF and an equivalent series resistance (ESR) of 50 Ohms. It utilizes a glass-sealed package design for enhanced environmental protection. The physical dimensions are 5.0 mm in length, 3.2 mm in width, and 1.2 mm in height. This surface-mount device is designed for precision timing applications requiring stable oscillation.

Feature Summary

• Glass-sealed construction for environmental durability
• Surface-mount SMD package for automated assembly
• High frequency stability within specified temperature range

Applications

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

Procurement Notes

Verify the specific manufacturer datasheet for the QT532G series to confirm electrical parameters such as ESR and load capacitance match system requirements. Ensure the operating temperature range aligns with the intended application environment. Check for RoHS compliance status if required by regulatory standards. Confirm package dimensions fit the PCB footprint constraints.

Selection Notes

Select this component when a 16 MHz reference is required with ±30 ppm stability. Consider the 18 pF load capacitance compatibility with the oscillator circuit. Evaluate the 50 Ohm ESR against the driver strength of the host IC. The glass-seal feature offers advantages over ceramic packages in harsh environments.

Part Context

This part belongs to the QT532G series of quartz crystals. Similar variants exist with different frequencies such as 18.432 MHz or 24.000 MHz within the same package family. The series generally maintains consistent physical dimensions and mounting characteristics while varying electrical specifications like frequency and potentially ESR values depending on the specific model number.

Replacement Considerations

Equivalent parts must match the 16 MHz frequency, 18 pF load capacitance, and 5x3.2mm SMD package. Verify that substitute components offer comparable ±30 ppm stability and 50 Ohm ESR. Ensure the replacement also utilizes a glass-seal construction if environmental robustness is critical.
