What is AEC?

The Automotive Electronics Council (AEC) is the standardized body for establishing standards for reliable, high quality electronic components. Components meeting these specifications are suitable for use in the harsh automotive environment without additional component-level qualification testing.

Two committees work on the qualification testing standards:

  1. Quality Systems Committee
  2. Component Technical Committee

The Component Technical Committee defines the AEC-Q200 standards.

The complete AEC-Q200 Base pdf document “Stress Test Qualification for Passive Components” can be found on the AEC Council website for reference.

What is and AEC-Q200 Component?

An AEC-Q200 component is one that is capable of passing the tests specified within the AEC-Q200 documentation and can be expected to give a certain level of quality and reliability to the application it is utilized within. The tests performed in the qualification determine the ability of the component to withstand the temperature and physical stresses of automotive environments.

There are no “certifications” for AEC-Q200 qualification. Each supplier is to perform the qualification to AEC documents, consider your customer requirements and submit the data to the customer to verify compliance to AEC-Q200.

What are the AEC-Q200 Grades?

AEC standards classify components into different grades corresponding to their service temperature ranges. These grades define where the components can be used within an automotive application. AEC-Q200 provide five (5) grade categories, and components with a lower grade number must be able to withstand lower and higher temperatures.

What are the AEC-Q200 Testing Qualifications?

Table 5 of the AEC-Q200 “Stress Test Qualification for Passive Components” document contains a complete listing of the testing parameters for Magnetics, both Inductors and Transformers. These tests include a variety of methods to test the component’s ability to withstand severe conditions, including:

  • High Temperature Exposure
  • Temperature Cycling
  • Humidity Bias
  • High Temperature Operating Life
  • Terminal Strength (for axial and radial THT components)
  • Resistance to Solvents
  • Mechanical Shock
  • Vibration
  • Resistance to Soldering Heat
  • ESD
  • Solderability
  • Flammability

Components will also be measured to confirm the physical dimensions comply with the component detail specifications. In addition to this, there is a visual inspection performed to validate the device construction, marking and workmanship as well as pre and post electrical tests to verify the accuracy of the component.
