QT161S-37.400MEIY-T

Overview

The QT161S-37.400MEIY-T is a fundamental mode quartz crystal resonator manufactured by QST, operating at a nominal frequency of 37.4 MHz. It features a load capacitance of 8 pF and is housed in a compact 4-SMD, No Lead package with dimensions of 1.60mm x 1.20mm. The component utilizes the 'I' suffix to denote a frequency tolerance of ±20 ppm across an operating temperature range of -20°C to +70°C. This surface-mount device is designed for integration into space-constrained electronic circuits requiring stable clock signals.

Feature Summary

• Fundamental oscillation mode operation for precise frequency stability
• Ultra-miniature 4-SMD no-lead package design for automated surface-mount assembly
• Defined load capacitance specification ensuring accurate circuit matching

Applications

• Embedded communication systems requiring stable clock sources
• Microcontroller unit (MCU) clock generation circuits
• Portable consumer electronics with limited board space

Procurement Notes

Verify the specific suffix configuration against official QST documentation to ensure the correct temperature range and tolerance specifications are met for your application environment. Confirm that the 4-SMD no-lead footprint aligns with your PCB fabrication capabilities and soldering profiles. Cross-reference the part number with authorized distributors to validate authenticity and supply chain integrity before finalizing procurement orders.

Selection Notes

Select this component when a 37.4 MHz fundamental frequency is required within a tight spatial constraint. The ±20 ppm tolerance suits applications where moderate frequency accuracy is sufficient under standard commercial temperature conditions. Ensure the target circuit design supports an 8 pF load capacitance to maintain specified performance characteristics without additional external compensation components.

Part Context

The QT161S series represents QST's ultra-miniature crystal lineup, engineered for high-density surface-mount applications. These components utilize advanced thin-film technology to achieve small form factors while maintaining reliable oscillation characteristics. The series offers various frequency and tolerance options to support diverse digital timing requirements in modern compact electronic devices.

Replacement Considerations

Direct substitutes must match the 37.4 MHz frequency, 4-SMD no-lead package, and 8 pF load capacitance. Verify equivalent thermal stability and tolerance ratings from alternative manufacturers. Ensure pin compatibility and reflow soldering profile alignment to prevent mechanical or electrical failures during replacement procedures.
