QT161S-37.400MAHI-T

Overview

The QT161S-37.400MAHI-T is a surface-mount crystal resonator manufactured by QST, operating at a fundamental frequency of 37.4 MHz. This component features a compact 4-SMD, no-lead package with dimensions of 1.6 x 1.2 mm and a height of approximately 0.35 mm. It exhibits a frequency stability of ±30 ppm at 25°C and ±30 ppm over the temperature range of -40°C to +85°C. The device utilizes a load capacitance of 16 pF and is designed for high-reliability applications requiring precise timing signals in space-constrained electronic assemblies.

Feature Summary

• Compact surface-mount design suitable for automated assembly processes
• High frequency stability across standard industrial temperature ranges
• Optimized for low-profile circuit board layouts

Applications

• Microcontroller clock sources
• Communication module timing references
• Portable electronic device oscillators

Procurement Notes

Verify the specific suffix MAHI against official QST documentation to confirm load capacitance and temperature stability ratings. Ensure compatibility with reflow soldering profiles specified in the manufacturer datasheet. Cross-reference the part number with authorized distributors to avoid counterfeit components. Confirm that the 16 pF load capacitance matches the target circuit design requirements before finalizing procurement orders.

Selection Notes

Select this component when a 37.4 MHz reference signal is required within strict spatial constraints. The 1.6x1.2 mm footprint offers a smaller alternative to larger crystal packages. Consider the ±30 ppm stability rating for applications where moderate precision suffices. Verify that the operating temperature range of -40°C to +85°C aligns with the environmental conditions of the end product.

Part Context

This part belongs to the QT161S series of surface-mount crystals from QST. The series provides various frequency options and stability grades tailored for consumer electronics and industrial control systems. The specific model integrates quartz resonance elements into a hermetically sealed metal or ceramic housing, ensuring long-term frequency accuracy and reliability under mechanical stress.

Replacement Considerations

Direct substitutes include other 37.4 MHz SMD crystals with identical 1.6x1.2 mm footprints and 16 pF load capacitance. Verify equivalent stability ratings and temperature ranges when considering alternatives from manufacturers such as TXC. Ensure pinout compatibility and soldering thermal characteristics match the original design specifications.
