QT532G-8.000MAHE-T

Overview

The QT532G-8.000MAHE-T is an 8 MHz quartz crystal resonator manufactured by QST. It features a fundamental operating mode with a frequency tolerance and stability of ±30 ppm across the -40°C to +85°C temperature range. The component has a load capacitance of 12 pF and an equivalent series resistance (ESR) of 80 Ohms. It utilizes a 2-SMD, no-lead package with body dimensions of 5.0 mm x 3.2 mm x 1.2 mm.

Feature Summary

• Glass seal construction for enhanced environmental reliability
• Wide operating temperature range suitable for industrial applications
• Surface-mount design for automated assembly

Applications

• Industrial control systems
• Automotive electronics
• Microcontroller clock sources

Procurement Notes

Verify the manufacturer designation on official documentation, as this part number is also associated with TXC Corporation. Confirm that the specific suffix corresponds to the glass-sealed variant with 80 Ohm ESR. Ensure the ordering information matches the required 12 pF load capacitance and ±30 ppm stability specifications before procurement.

Selection Notes

Select this component when a robust, glass-sealed crystal is required for harsh environments. The 80 Ohm ESR and 12 pF load capacitance must match the oscillator circuit design. Consider the 5x3.2 mm footprint for space-constrained PCB layouts requiring high thermal stability.

Part Context

This part belongs to the QT532G series of surface-mount crystals. The series offers various frequencies and packages, with this specific model providing an 8 MHz output in a compact SMD form factor designed for reliable performance in demanding conditions.

Replacement Considerations

Direct substitutes include other manufacturers' 8 MHz crystals with identical 5x3.2 mm footprints, 12 pF load capacitance, and ±30 ppm stability. Verify ESR compatibility and pin configuration before substitution.
