AY-38.400MFNV-T

Crystals Overview

The AY-38.400MFNV-T is a 38.4 MHz fundamental mode quartz crystal resonator manufactured by TXC Corporation. It features an 8 pF load capacitance and ±15 ppm frequency tolerance at 25°C, with ±50 ppm stability across the -40°C to +125°C temperature range. The component utilizes a 4-SMD, no lead (CSMD) package measuring 2.0 mm x 1.6 mm x 0.5 mm. Designed for automotive applications, it holds AEC-Q200 certification and operates in a base harmonic mode.

Crystals Feature Summary

• AEC-Q200 certified for automotive reliability standards
• Seam seal construction for enhanced environmental protection
• Wide operating temperature range suitable for harsh environments

Crystals Applications

• Automotive electronic control units
• In-vehicle infotainment systems
• Industrial control modules requiring high thermal stability

Crystals Procurement Notes

Verify that the specific part number includes the 'V' suffix indicating seam seal construction, as this affects environmental durability. Confirm AEC-Q200 compliance requirements match your system's qualification standards. Ensure the 8 pF load capacitance aligns with the host oscillator circuit design to maintain the specified ±15 ppm tolerance. Check moisture sensitivity levels and storage conditions prior to assembly.

Crystals Selection Notes

Select this component when automotive-grade reliability and wide temperature operation are required. The 2.0x1.6 mm footprint offers space efficiency compared to larger packages. Consider the ±50 ppm total stability over temperature for precision timing needs. Verify compatibility with the target application's voltage and drive level constraints before finalizing the design.

Crystals Part Context

This crystal belongs to TXC's automotive-grade quartz series, designed specifically for demanding vehicular environments. It complements other models in the AY series that offer different frequencies or package sizes. The seam seal technology distinguishes it from standard ceramic-packaged crystals, providing superior resistance to humidity and contaminants common in automotive under-hood applications.

Crystals Replacement Considerations

Direct substitutes include AY-38.400MFNQ-T if non-seal construction is acceptable. Other 38.4 MHz crystals with identical 8 pF load capacitance and 2.0x1.6 mm dimensions may be considered, provided they meet AEC-Q200 standards. Verify equivalent ESR and drive level specifications to ensure circuit compatibility.
