Frequently Asked Questions
What AEC-Q200 tests does the AF-100uF-50V pass?
The AF-100uF-50V passes all AEC-Q200 required tests including: high temperature storage, temperature cycling (-40°C to +125°C), vibration resistance, mechanical shock, humidity resistance, and solderability. These rigorous tests ensure reliable performance in automotive environments.
For automotive applications, always verify AEC-Q200 qualification status.
What is the expected lifetime in automotive applications?
The rated lifetime is 2,000 hours at 125°C. In typical automotive applications with proper derating, actual field lifetime can exceed 10 years. The Arrhenius relationship applies - every 10°C reduction approximately doubles the lifetime. Most automotive applications operate well below the maximum rated temperature.
For maximum reliability, operate with voltage derating and minimize operating temperature.
What voltage derating is recommended for automotive applications?
For automotive applications, industry best practice recommends 50% voltage derating for maximum reliability. For this 50V rated capacitor, limit operating voltage to 25V. This conservative derating accounts for voltage transients, load dumps, and the critical nature of automotive systems.
Use 50% voltage derating for automotive applications to ensure maximum reliability.
Can this capacitor be used in engine compartment applications?
The AF-100uF-50V with 125°C rating is suitable for many engine compartment applications. However, for extreme under-hood temperatures, consider the AH series with 150°C rating. Always verify the maximum expected temperature in the specific mounting location.
For extreme temperature locations, select AH series with 150°C rating.
What documentation is available for automotive qualification?
Complete PPAP documentation is available including: design records, material certifications, AEC-Q200 test reports, process flow diagrams, PFMEA, control plan, measurement system analysis, dimensional results, material performance test results, initial process studies, qualified laboratory documentation, appearance approval report, sample production parts, master sample, checking aids, and customer-specific requirements.
Contact our sales team for complete PPAP documentation package.
What is the ESR specification for automotive applications?
The ESR at 100kHz is approximately 0.8 Ohm. This provides good filtering performance for automotive electronics. The ESR is optimized for the switching frequencies typical in automotive DC-DC converters and LED drivers. Lower ESR reduces self-heating and improves efficiency.
For applications requiring lower ESR, contact our FAE team for recommendations.
