QT325S-10.000MAHE-T

Overview

The QT325S-10.000MAHE-T is a quartz crystal resonator manufactured by QST, designed for surface-mount applications. It operates at a nominal frequency of 10 MHz with a load capacitance of 12 pF and an equivalent series resistance of 150 Ohms. The component features a 4-SMD, no-lead package with dimensions of 3.2mm x 2.5mm x 0.7mm. Frequency stability is rated at ±30ppm across the operating temperature range of -40°C to +85°C.

Feature Summary

• Seam seal construction for enhanced environmental protection
• Surface-mount design compatible with automated assembly processes
• Wide operating temperature range suitable for industrial environments

Applications

• Microcontroller clock sources
• Communication module timing references
• Consumer electronics signal generation

Procurement Notes

Verify the specific suffix HE against official QST documentation to confirm exact tolerance and temperature specifications. Ensure compatibility with reflow soldering profiles defined in the manufacturer datasheet. Cross-reference package dimensions with PCB footprint requirements to prevent mechanical interference during assembly.

Selection Notes

Select this component when a 10 MHz reference is required in a compact SMD form factor. Consider the 12pF load capacitance requirement of the host oscillator circuit. Evaluate the ±30ppm stability against system timing accuracy needs within the specified -40°C to +85°C operational window.

Part Context

This part belongs to the QT325S series of seam-seal quartz crystals. The series offers various frequency options within the same 3.2x2.5mm package. The MAHE suffix indicates specific electrical characteristics including load capacitance and stability limits distinct from other suffix variants in the product line.

Replacement Considerations

Direct substitutes include the TXC Corporation QT325S-10.000MAHE-T, which shares identical electrical parameters and physical dimensions. Verify pinout and mounting pad layout compatibility before substitution.
