QT161S-37.400MAAE-T

Overview

The QT161S-37.400MAAE-T is a surface-mount crystal oscillator manufactured by QST, operating at a nominal frequency of 37.4 MHz. It features a frequency tolerance of ±30 ppm and utilizes a load capacitance of 12 pF. The component is housed in a compact 4-SMD, No Lead package with dimensions of 1.6 x 1.2 x 0.35 mm. Designed for reliability, it complies with RoHS3 standards and supports an operating temperature range of -20°C to +70°C.

Feature Summary

• Compact surface-mount design suitable for space-constrained PCB layouts
• High frequency stability with ±30 ppm tolerance
• Compliance with RoHS3 environmental standards

Applications

• Industrial control systems requiring stable clock signals
• Consumer electronics utilizing 37.4 MHz timing references
• Communication modules needing precise frequency generation

Procurement Notes

Verify the specific suffix 'AAE' against official QST documentation to confirm the 12 pF load capacitance and ±30 ppm tolerance specifications. Ensure the requested quantity matches the manufacturer's standard packaging requirements. Confirm RoHS3 compliance status directly with the supplier or datasheet before finalizing procurement orders.

Selection Notes

Select this component when a 37.4 MHz frequency is required with moderate stability. The 12 pF load capacitance must match the oscillator circuit design. Consider the -20°C to +70°C temperature range for industrial applications. Verify that the 4-SMD package fits the available footprint on the target printed circuit board.

Part Context

This part belongs to the QT161S series of surface-mount crystals from QST. The series offers various frequencies and tolerances. The QT161S-37.400MAAE-T specifically targets applications needing 37.4 MHz operation. It shares the same physical package dimensions as other variants in the QT161S family but differs in electrical parameters.

Replacement Considerations

Direct substitutes include the QT161S-37.400MEEV-T (±10 ppm) and QT161S-37.400MAAV-T (8 pF load). Verify load capacitance and tolerance differences before substitution. Ensure the replacement maintains the 4-SMD No Lead package form factor.
