QT252S-38.400MEEV-T

Overview

The QT252S-38.400MEEV-T is a surface-mount crystal oscillator manufactured by QST Products, LLC. It operates at a fundamental frequency of 38.4 MHz with a frequency tolerance of ±10 ppm at 25°C and ±10 ppm over the temperature range of -20°C to +70°C. The component features a load capacitance of 8 pF and utilizes a 4-SMD, No Lead package with dimensions of 2.5 mm x 2.0 mm. It is lead-free and RoHS compliant.

Feature Summary

• Compact 4-SMD no-lead surface mount package design
• High frequency stability with ±10 ppm tolerance across specified temperature range
• RoHS compliant and lead-free construction

Applications

• Clock signal generation for microprocessors
• Timing reference for communication interfaces
• Frequency control in consumer electronics

Procurement Notes

Verify that the specific part number QT252S-38.400MEEV-T matches the required 38.4 MHz frequency and 8 pF load capacitance. Confirm that the 4-SMD no-lead package dimensions are compatible with the PCB footprint. Ensure compliance with RoHS standards if required by the end product regulations. Check manufacturer documentation for storage and handling guidelines regarding moisture sensitivity levels.

Selection Notes

Select this component when a precise 38.4 MHz timing source is required in space-constrained designs. The ±10 ppm stability suits applications needing moderate precision without the cost of higher-grade oscillators. The 8 pF load capacitance must match the circuit design requirements. Consider the operating temperature range of -20°C to +70°C against environmental conditions.

Part Context

This part belongs to the QT252S series of surface-mount crystals from QST Products. The series offers various frequencies and package sizes optimized for modern electronic assemblies. The 'MEEV' suffix typically denotes specific electrical characteristics and packaging variations within the product line, distinguishing it from other variants like the MAJJ or MEEQ series.

Replacement Considerations

Direct substitutes may include other 38.4 MHz crystals with identical 8 pF load capacitance and ±10 ppm stability in a 4-SMD no-lead package. Verify pin compatibility and thermal characteristics before substitution. Cross-reference with QST's official replacement guide or equivalent parts from other manufacturers ensuring identical electrical parameters.
