QT252S-38.400MEKQ-T

Crystals Overview

The QT252S-38.400MEKQ-T is a surface-mount quartz crystal resonator manufactured by FTS, designed for precision timing applications in electronic circuits. It operates at a nominal frequency of 38.4 MHz with a load capacitance of 10 pF. The component features a frequency tolerance and stability of ±10 ppm across specified temperature ranges. Housed in a compact 2.50mm x 2.00mm seam seal package, it utilizes a four-pad ceramic construction to ensure reliable performance in space-constrained designs.

Crystals Feature Summary

• Seam seal construction provides robust environmental protection and long-term reliability.
• Compact surface-mount footprint facilitates automated assembly and high-density PCB layouts.
• Four-pad design ensures stable mechanical mounting and consistent electrical performance.

Crystals Applications

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

Crystals Procurement Notes

Verify the specific suffix 'MEKQ' against official FTS documentation to confirm exact specifications, as ordering codes may denote unique packaging or testing requirements. Ensure compatibility with reflow soldering profiles defined in the datasheet. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Confirm availability of full traceability documentation if required for quality assurance protocols.

Crystals Selection Notes

Select this component when a 38.4 MHz reference is required with ±10 ppm stability. Evaluate the 10 pF load capacitance requirement against the oscillator circuit design. Consider the 2.50mm x 2.00mm dimensions for board space constraints. Verify that the operating temperature range meets the application's environmental conditions before finalizing the selection.

Crystals Part Context

This crystal belongs to the QT252S series of surface-mount quartz resonators. The series is characterized by small form factors suitable for portable electronics. Similar models in the family include variants with different frequencies and tolerances, such as the QT252S-26.000METC-T, which shares the same physical package but differs in frequency and potentially testing parameters.

Crystals Replacement Considerations

Direct substitutes must match the 38.4 MHz frequency, 10 pF load capacitance, and ±10 ppm stability. Check equivalent parts from other manufacturers like TXC or CTS-Frequency Controls, ensuring identical package dimensions and pin configuration. Verify that any alternative component meets the same thermal and electrical specifications without requiring circuit redesign.
