AZ-37.400MEQQ-T

Crystals Overview

The AZ-37.400MEQQ-T is a 37.4 MHz fundamental mode quartz crystal resonator manufactured by TXC Corporation. It features a 2.5x2.0 mm surface-mount package with four pads and a seam seal construction. The component operates within an extended temperature range of -40°C to +105°C, maintaining frequency stability of ±30 ppm across this span and ±10 ppm at 25°C. It utilizes a 10 pF load capacitance and exhibits an equivalent series resistance of 80 Ohms. Certified to AEC-Q200 standards, it is designed for automotive applications requiring high reliability.

Crystals Procurement Notes

Verify the complete part number including suffixes to ensure correct load capacitance and tolerance specifications. Confirm that the intended application environment falls within the specified -40°C to +105°C operational range. Ensure compatibility with the 10 pF load capacitance requirement of the host circuit design before procurement.

Crystals Selection Notes

Select this component when automotive certification (AEC-Q200) is mandatory for the project. Choose this model over standard industrial crystals if operation in extreme temperatures below -40°C or above +85°C is required. Ensure the system design supports the specific 10 pF load capacitance to maintain accurate frequency generation.

Crystals Part Context

This part belongs to the AZ series of high-reliability quartz crystals from TXC Corporation. The series is specifically engineered for automotive electronics, distinguishing itself from general-purpose consumer-grade oscillators through rigorous qualification testing and robust packaging technologies designed to withstand mechanical stress and thermal cycling.

Crystals Replacement Considerations

Direct substitutes must match the 37.4 MHz frequency, 10 pF load capacitance, and AEC-Q200 certification. Verify that alternative components support the same -40°C to +105°C temperature range and 4-SMD footprint to ensure mechanical and electrical compatibility.
