QT216S-37.400METE-T

Overview

The QT216S-37.400METE-T is a surface-mount crystal oscillator manufactured by QST, designed for precision timing applications. It operates at a fundamental frequency of 37.4 MHz with a standard load capacitance of 12 pF. The component exhibits a frequency tolerance and stability of ±10 ppm at 25°C and across the operating temperature range of -30°C to +85°C. It features an equivalent series resistance (ESR) of 50 Ω and utilizes a compact SMD2016-4P package, ensuring reliable performance in space-constrained electronic designs.

Feature Summary

• Fundamental operating mode for stable clock generation
• Compact SMD2016-4P surface mount package design
• Wide industrial temperature range capability
• Low equivalent series resistance for efficient operation

Applications

• Precision timing circuits requiring 37.4 MHz reference
• Industrial control systems operating in wide temperature environments
• Embedded devices utilizing surface mount technology constraints

Procurement Notes

Verify the manufacturer designation as QST or TXC Corporation, as source data indicates potential branding variations. Confirm the specific suffix METE-T aligns with the required 12 pF load capacitance and ±10 ppm stability specifications. Ensure the package type matches the SMD2016-4P footprint requirements for your PCB layout. Cross-reference the datasheet version to guarantee compatibility with current production standards.

Selection Notes

Select this component when a 37.4 MHz fundamental frequency is strictly required. The ±10 ppm stability suits applications needing moderate precision without active compensation. The -30°C to +85°C range supports general industrial use rather than extreme automotive conditions. Consider the 50 Ω ESR value for circuit impedance matching. The small form factor makes it suitable for dense board layouts where larger oscillators do not fit.

Part Context

This part belongs to the QT216S series of surface-mount crystals from QST. The series offers various frequencies within the 2.0x1.6 mm package. Similar models include variants like QT216S-48.000METE-T for different clock speeds. The product line focuses on providing cost-effective, reliable timing solutions for consumer and industrial electronics using standard quartz crystal technology.

Replacement Considerations

Direct substitutes may include other 37.4 MHz crystals in the SMD2016-4P package with identical ±10 ppm stability. Verify that any replacement maintains the 12 pF load capacitance specification. Check if alternative manufacturers offer compatible parts with similar ESR values. Ensure the replacement supports the same -30°C to +85°C operating temperature range.
