AM-40.000MDGE-T

Crystals Overview

The AM-40.000MDGE-T is a 40 MHz fundamental mode quartz crystal manufactured by TXC Corporation, designed for surface-mount applications in automotive environments. It features a 4-SMD no-lead package with dimensions of 3.20mm x 2.50mm and a maximum height of 0.80mm. The component operates within a temperature range of -40°C to +85°C and holds AEC-Q200 qualification. Key electrical parameters include a load capacitance of 12 pF, an equivalent series resistance (ESR) of 60 Ohms, a frequency tolerance of ±20 ppm, and a frequency stability of ±50 ppm.

Crystals Feature Summary

• AEC-Q200 qualified for automotive reliability standards
• Fundamental oscillation mode operation
• Compact 4-SMD no-lead surface mount packaging

Crystals Applications

• Automotive electronic systems requiring high-frequency timing
• Microcontroller clock sources in harsh thermal environments
• Communication modules in vehicle networks

Crystals Procurement Notes

Verify the specific suffix 'MDGE' against the official TXC ordering guide to confirm the exact tolerance and stability specifications. Ensure the selected variant matches the required AEC-Q200 certification level for your target application. Cross-reference the package dimensions with your PCB footprint library before finalizing the design.

Crystals Selection Notes

Select this component when a fundamental mode crystal with ±20 ppm tolerance and ±50 ppm stability is required for automotive use. The 12 pF load capacitance must match the oscillator circuit design. Consider the 60 Ohm ESR value for drive level calculations. The 4-SMD package size suits space-constrained automotive boards.

Crystals Part Context

This part belongs to the AM series of automotive crystals from TXC Corporation. These components are engineered for high-reliability applications where strict frequency stability and thermal performance are critical. The series supports various frequencies and packages, with this specific model optimized for 40 MHz operations in compact SMD form factors.

Crystals Replacement Considerations

AM-40.000MAGE-T and AM-40.000MENE-T are listed as parameter-equivalent alternatives. Verify that the tolerance and stability differences between these substitutes meet the system requirements before substitution.
