AA-37.050MAHV-T

Crystals Overview

The AA-37.050MAHV-T is a surface-mount crystal resonator manufactured by TXC Corporation, designed for high-frequency applications requiring precise timing. It operates at a nominal frequency of 37.05 MHz with a load capacitance of 8 pF and an equivalent series resistance (ESR) of 50 Ohms. The component features a frequency tolerance of ±30 ppm and stability of ±50 ppm. It supports an extended operating temperature range from -40°C to +125°C and meets AEC-Q200 automotive qualification standards. The package dimensions are 3.2 mm x 2.5 mm x 1.2 mm, utilizing SMD/SMT termination.

Crystals Feature Summary

• Automotive-grade reliability certified under AEC-Q200 standards
• Extended temperature operation capability up to 125°C
• Compact surface-mount design for space-constrained PCB layouts

Crystals Applications

• Automotive electronic control units
• High-stability communication modules
• Industrial instrumentation timing circuits

Crystals Procurement Notes

Verify the specific suffix HV against official TXC documentation to confirm pinout and loading capacitance requirements. Ensure the selected variant matches the target circuit's load capacitance specifications. Confirm that the AEC-Q200 certification aligns with project quality standards. Cross-reference the package dimensions with the mechanical footprint in the datasheet before finalizing the design.

Crystals Selection Notes

Select this component when automotive-grade durability and wide temperature tolerance are required. The 37.05 MHz frequency suits specific clocking needs distinct from standard 36.864 MHz or 37.125 MHz alternatives. Consider the 8 pF load capacitance requirement for oscillator circuit design. Evaluate the 50 Ohm ESR against the oscillator amplifier's drive level capabilities.

Crystals Part Context

This part belongs to the AA series of miniature crystals from TXC Corporation. The series focuses on small form factors suitable for modern electronics. The AA-37.050MAHV-T specifically targets automotive and industrial sectors due to its robust thermal performance and qualification status.

Crystals Replacement Considerations

Direct substitutes include other 37.05 MHz crystals with identical 8 pF load capacitance and AEC-Q200 certification. Verify mechanical compatibility with the 3.2 x 2.5 mm footprint. Check if alternative manufacturers offer equivalent frequency stability and ESR values.
