QT216S-37.400METC-T

Overview

The QT216S-37.400METC-T is a surface-mount crystal oscillator manufactured by QST Products, LLC. It operates at a fundamental frequency of 37.4 MHz with a load capacitance of 16pF and an equivalent series resistance of 50 Ohms. The component features a ±10ppm frequency tolerance at 25°C and supports an operating temperature range of -30°C to +85°C. It utilizes a 4-SMD, No Lead package with a maximum seated height of 0.020 inches (0.50mm).

Feature Summary

• Fundamental mode operation for stable frequency generation.
• Compact 4-SMD no-lead surface mount package design.
• Wide industrial temperature range capability from -30°C to +85°C.

Applications

• Digital signal processing controller timing references.
• Motor control system clock sources.
• Real-time embedded task synchronization circuits.

Procurement Notes

Verify the specific suffix METC-T against official QST documentation to confirm exact tolerance and temperature specifications. Ensure compatibility with existing PCB footprint requirements for the 4-SMD no-lead package. Cross-reference datasheet parameters for load capacitance and ESR values prior to integration into final designs.

Selection Notes

Select this component when a precise 37.4 MHz reference is required in space-constrained applications. The ±10ppm tolerance suits systems needing higher stability than standard ±30ppm crystals. Consider the 16pF load capacitance requirement for proper circuit matching and frequency accuracy within the specified industrial temperature range.

Part Context

This part belongs to the QT216S series of surface-mount crystals. Similar variants include the QT216S-37.400MAAV-T which offers ±30ppm tolerance, and the QT216S-40.000METQ-T which shares the ±10ppm specification but differs in frequency. The series provides options for various frequencies and tolerances within the same physical footprint.

Replacement Considerations

Direct substitutes may include other 37.4 MHz crystals with identical 4-SMD no-lead dimensions and 16pF load capacitance. Verify that alternative parts meet the ±10ppm tolerance and -30°C to +85°C operating range requirements to ensure functional equivalence in the target application.
