QT216S-38.400MDIQ-T

Overview

The QT216S-38.400MDIQ-T is a quartz crystal resonator manufactured by QST Products, designed for surface-mount applications. It operates at a fundamental frequency of 38.4 MHz and utilizes a 4-SMD, no-lead package with dimensions of 2.0x1.6 mm. The component exhibits a frequency tolerance of ±20 ppm at 25°C and maintains stability within the same range across an operating temperature span of -20°C to +70°C. It requires a load capacitance of 10 pF for proper circuit integration.

Feature Summary

• Compact surface-mount design suitable for space-constrained PCB layouts
• Stable frequency performance across standard commercial temperature ranges
• Lead-free construction compliant with environmental standards

Applications

• Microcontroller clock sources
• Communication module timing references
• Digital signal processing circuits

Procurement Notes

Verify the specific suffix 'DIQ' against manufacturer documentation to confirm exact packaging configuration and tape-and-reel specifications. Ensure that the 10 pF load capacitance requirement aligns with the target oscillator circuit design to maintain the specified ±20 ppm accuracy. Cross-reference the operating temperature range with application thermal profiles.

Selection Notes

Select this component when a 38.4 MHz reference is required in a minimal footprint form factor. The 2.0x1.6 mm package size offers advantages for high-density board designs compared to larger crystals. Consider the ±20 ppm tolerance sufficient for general digital logic timing where higher precision oscillators are not mandated.

Part Context

This part belongs to the QT216S series of quartz crystals from QST Products. The series provides various frequency options within the same physical footprint, allowing designers to standardize on a single package type while adjusting frequencies through different part numbers. The SMD format facilitates automated assembly processes.

Replacement Considerations

Direct substitutes include other 38.4 MHz crystals in 2.0x1.6 mm packages with matching 10 pF load capacitance and ±20 ppm tolerance. Verify pin compatibility and electrical parameters before swapping manufacturers.
