Frequently Asked Questions (FAQ)
Q: How does the CD 295 differ from the CD 296 series?
A: While both are 105°C snap-in capacitors, the CD 295 is optimized for overall long life and reliability, making it a balanced choice. The CD 296 series is specifically designed for higher ripple current handling, often in a more compact case size for the same CV rating, making it suitable for applications with extreme ripple stress.
Q: Can this capacitor be used in an automotive application?
A: The CD 295 is an industrial-grade capacitor. For automotive applications, it is crucial to use AEC-Q200 qualified parts. Jianghai offers dedicated automotive series capacitors. Please contact our FAE team for a suitable recommendation.
Q: What is the expected lifetime at a lower operating temperature, like 65°C?
A: The lifetime of an aluminum electrolytic capacitor increases exponentially as the operating temperature decreases. A general rule of thumb (Arrhenius's Law) states that for every 10°C reduction in operating temperature, the lifetime doubles. So, operating at 65°C (40°C lower than 105°C) could extend the life by a factor of 2^4 = 16. The real lifetime also depends heavily on the ripple current stress.
