Crystals Procurement Notes

Verify that the specific part number AZ-37.400MAGQ-T matches the required frequency tolerance and stability specifications for the target application. Confirm compliance with AEC-Q200 standards if automotive qualification is mandatory. Ensure the 4-SMD package dimensions align with the printed circuit board layout constraints. Check for RoHS compliance status prior to final procurement decisions.

Crystals Selection Notes

Select this component when automotive-grade reliability and compact form factors are required for 37.4 MHz timing circuits. The ±30 ppm tolerance suits applications needing moderate precision without the cost of oscillators. Consider the 10 pF load capacitance requirement to ensure proper circuit matching. The wide temperature range makes it suitable for harsh automotive environments compared to commercial-grade alternatives.

Crystals Part Context

This component belongs to the AZ series of quartz crystals from TXC Corporation, which specializes in high-reliability timing solutions. The series is characterized by seam seal technology and adherence to automotive quality standards. It serves as a passive frequency-determining element within larger electronic assemblies, providing the reference clock necessary for microcontroller and communication interface operations.

Crystals Replacement Considerations

Direct substitutes include other AZ-series variants such as AZ-37.400MEQQ-T or AZ-37.400MEIQ-T, provided they meet the same electrical and mechanical requirements. Verify that any replacement maintains the AEC-Q200 certification and identical package dimensions to ensure compatibility with existing manufacturing processes.
