Process for AEC-Q200 Certification of Automotive Aluminum Electrolytic Capacitors

In recent years, the automotive electronic components market has been booming, with AEC-Q200 certification serving as the entry ticket for automotive aluminum electrolytic capacitors into this sector. Today, we will delve into the knowledge about automotive aluminum electrolytic capacitors.

 

The Difference Between Industrial-grade and Automotive-grade Aluminum Electrolytic Capacitor

The main difference between industrial-grade and automotive-grade components lies in their operating temperature range. Typically, industrial-grade aluminum electrolytic capacitors operate between -40°C to +85°C, whereas automotive-grade capacitors operate between -40°C to +150°C. However, the differences extend beyond temperature ranges. Automotive-grade aluminum electrolytic capacitors generally exhibit superior performance, stronger temperature adaptability, and better immunity to interference (including resistance to temperature extremes, temperature fluctuations, and other reliability factors).

Common types of automotive-grade aluminum electrolytic capacitors include through-hole aluminum electrolytic capacitors, surface-mount aluminum electrolytic capacitors, snap-in aluminum electrolytic capacitors, and bolt-type aluminum electrolytic capacitors.

 

The Necessity of AEC-Q200 Certification for Automotive-grade Aluminum Electrolytic Capacitors

Automobiles operate in demanding environments such as outdoors, high temperatures, extreme cold, and humidity. Their design life spans are typically 15 years or 200,000 kilometers, with iteration cycles much longer than those of consumer electronics (2-3 years). Automotive applications demand high standards for environmental resilience, vibration resistance, shock resistance, reliability, and consistency. Component standards generally prioritize military > automotive > industrial > consumer electronics. OEMs require Tier 1 suppliers to use automotive-grade components to ensure product quality and reliability in automotive applications.

Automotive Grade refers to components meeting automotive-grade requirements, widely recognized in the industry as components certified under AEC-Q standards.

 AEC-Q certification applies to automotive chips, passive components, discrete semiconductor devices, and other components, with specific testing standards tailored to each type of device.

Aluminum electrolytic capacitors, classified as passive components, must undergo AEC-Q200 third-party testing and certification to enter the automotive electronics market.

 

Test Items for AEC-Q200 Certification of Automotive Grade Aluminum Electrolytic Capacitors

AEC-Q200 certification for automotive-grade aluminum electrolytic capacitors involves testing according to Table 3 of AEC-Q200 Rev. D standards, encompassing 19 test items. A total of 618 PCS samples are required for testing, with zero failures accepted for all tests. Specific test items include:
