QT161S-37.400METE-T

Overview

The QT161S-37.400METE-T is a quartz crystal resonator manufactured by QST, operating at a fundamental frequency of 37.4 MHz. It features a compact 1.6x1.2 mm surface-mount package with four solder pads and no lead construction. The component exhibits a frequency tolerance of ±10 ppm at 25°C and maintains stability within ±10 ppm across an operating temperature range of -30°C to +85°C. It utilizes a load capacitance of 12 pF and is designed for seam seal technology applications requiring precise timing signals in space-constrained electronic circuits.

Feature Summary

• Seam seal construction for enhanced environmental protection
• Compact 1.6x1.2 mm SMD footprint
• High frequency stability across industrial temperature ranges

Applications

• Microcontroller clock sources
• Communication module timing
• Consumer electronics oscillators

Procurement Notes

Verify the complete part number including suffixes to ensure correct frequency tolerance and temperature range specifications. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Cross-reference datasheet parameters against design requirements to validate load capacitance and package dimensions for PCB layout compatibility.

Selection Notes

Select this component when a 37.4 MHz reference signal is required in minimal space. Ensure circuit design accommodates the 12 pF load capacitance specification. Verify that the -30°C to +85°C operating range meets environmental conditions. Compare against alternative packages if board space allows for larger components with different stability profiles.

Part Context

This model belongs to the QT161S series of surface-mount crystals from QST. The series offers various frequency options and tolerance grades within standardized small outlines. The METE-T suffix indicates specific stability and packaging characteristics distinct from other variants like MAAV or MDDE which may offer different ppm tolerances or temperature ranges.

Replacement Considerations

Direct substitutes include QT161S-37.400MEEV-T and QT161S-37.400METI-T from QST, provided they match the 12 pF load capacitance and ±10 ppm stability requirements. Verify pinout and mechanical dimensions before substitution.
