Lelon Automotive Capacitor Application Guide
This technical reference document provides detailed information about lelon product specifications, characteristics, and performance parameters. Use this information to support your design and analysis activities.
Electrical characteristics are specified over the operating temperature range unless otherwise noted. Parameters are guaranteed by design, testing, or statistical analysis. Typical values is the most likely parametric norm at 25°C.
Thermal characteristics require careful attention during system design. The junction-to-ambient thermal resistance depends on the mounting configuration, PCB copper area, and airflow conditions. Use thermal simulation tools to predict operating temperatures under actual conditions.
Reliability data is based on accelerated life testing and field failure analysis. Mean time between failures (MTBF) calculations follow industry-standard methodologies. Contact BeiLuo for detailed reliability reports and qualification data.

Frequently Asked Questions
1. What is AEC-Q200?
AEC-Q200 is the global standard for automotive passive components. It defines rigorous testing including temperature cycling, vibration, and shock. For detailed specifications and application support on lelon products, refer to the datasheet or contact our team.
2. What derating is required?
50% voltage derating is recommended for automotive to handle load dumps and transients. For detailed specifications and application support on lelon products, refer to the datasheet or contact our team.
3. What temperature rating?
Use 125°C for most applications, 150°C for extreme under-hood locations. For detailed specifications and application support on lelon products, refer to the datasheet or contact our team.
4. What documentation is needed?
PPAP documentation including design records, test reports, PFMEA, control plan, and ongoing reliability data. For detailed specifications and application support on lelon products, refer to the datasheet or contact our team.
5. How do automotive differ from industrial?
Automotive capacitors have AEC-Q200 qualification, enhanced construction, extended temperature ratings, and stricter quality controls. For detailed specifications and application support on lelon products, refer to the datasheet or contact our team.
6. What lifetime in automotive?
With proper design, 15+ year operational life matching vehicle lifetime. For detailed specifications and application support on lelon products, refer to the datasheet or contact our team.
7. What are common automotive requirements?
AEC-Q200, extended temperature, vibration resistance, humidity resistance, and complete documentation. For detailed specifications and application support on lelon products, refer to the datasheet or contact our team.
8. How to handle load dump?
Use 50% voltage derating to provide margin for load dump transients up to 100V in 12V systems. For detailed specifications and application support on lelon products, refer to the datasheet or contact our team.
