QT532G-20.000MAHE-T

Overview

The QT532G-20.000MAHE-T is a quartz crystal resonator manufactured by TXC Corporation under the QST brand, designed for surface-mount applications. It operates at a fundamental frequency of 20 MHz with a load capacitance of 12 pF and an equivalent series resistance (ESR) of 50 Ohms. The component features a frequency tolerance and stability of ±30 ppm across the operating temperature range of -40°C to +85°C. It utilizes a glass-sealed ceramic package with dimensions of 5.0 mm x 3.2 mm x 1.2 mm and is supplied in reel packaging.

Feature Summary

• Utilizes a glass-sealed ceramic construction for enhanced environmental durability and reliability.
• Provides precise frequency control with ±30 ppm stability across industrial temperature ranges.
• Features a compact SMD form factor suitable for high-density PCB layouts.

Applications

• Microcontroller clock sources
• Communication module timing references
• Industrial control system oscillators

Procurement Notes

Verify manufacturer designation as TXC Corporation when sourcing QST branded components. Confirm RoHS compliance status through official datasheets prior to integration. Ensure supply chain partners provide valid traceability documentation for automotive or industrial grade requirements. Validate package dimensions against PCB footprint specifications to prevent assembly errors during production.

Selection Notes

Select this component for designs requiring stable 20 MHz timing within a 5x3.2mm envelope. Consider the 12pF load capacitance requirement for oscillator circuit tuning. Evaluate ESR limits against driver strength capabilities. Compare ±30 ppm stability against application jitter sensitivity thresholds. Assess thermal performance needs against the -40 to +85C operational rating.

Part Context

This part belongs to the QT532G series of MHz quartz crystals from TXC Corporation. The series offers various frequency options within the same 5.0x3.2mm package. It serves as a passive frequency-determining element in electronic circuits, distinct from active oscillators like the QTM532 series. The component relies on external amplifier circuits to generate clock signals.

Replacement Considerations

QT532G-20.000MAHJ-T is a documented substitute variant within the same series. Verify pin compatibility and electrical parameters before substitution. Ensure replacement parts meet identical frequency tolerance and load capacitance requirements for circuit stability.
