QT532G-12.000MAHE-T

Overview

The QT532G-12.000MAHE-T is a quartz crystal oscillator manufactured by QST, operating at a nominal frequency of 12 MHz. It features a load capacitance of 12 pF and an equivalent series resistance of 50 Ohms. The component exhibits a frequency stability of ±30 ppm across the full operating temperature range of -40°C to +85°C. It utilizes a glass-sealed construction within a 5.0 mm x 3.2 mm surface-mount package with no lead design.

Feature Summary

• Glass-sealed quartz crystal construction for enhanced environmental stability
• Surface-mount design compatible with automated assembly processes
• Wide operating temperature range suitable for industrial environments

Applications

• Industrial control systems requiring precise timing references
• Automotive electronics operating in harsh thermal conditions
• Microcontroller clock sources for embedded applications

Procurement Notes

Verify the specific suffix HE against the manufacturer's current datasheet to confirm package dimensions and sealing type. Ensure the load capacitance matches the host circuit design requirements. Confirm active status directly with QST or authorized distributors before ordering.

Selection Notes

Select this component when a 12 MHz reference with ±30 ppm stability is required in a compact SMD form factor. The glass seal offers superior protection compared to standard ceramic packages. Consider the 50 Ohm ESR for oscillator circuit compatibility.

Part Context

This part belongs to the QT532G series of MHz quartz crystals from QST. The series provides various frequency options in a standardized 5.0x3.2mm footprint. The MAHE suffix indicates specific terminal and sealing characteristics distinct from other variants in the lineup.

Replacement Considerations

Direct substitutes include the TXC Corporation version QT532G-12.000MAHE-T, which shares identical electrical specifications and physical dimensions. Verify pinout compatibility before substitution.
