Frequently Asked Questions
What is the maximum ripple current for the SF-22000uF-80V?
The rated ripple current is 12A at 85°C and 120Hz. This very high rating makes it suitable for the most demanding industrial applications. At lower temperatures, the capacitor can handle even higher ripple currents - approximately 14A at 65°C.
For applications exceeding 12A ripple current, use multiple capacitors in parallel.
What is the expected lifetime of the SF-22000uF-80V?
The rated lifetime is 2,000 hours at 85°C. Using the Arrhenius equation, at 65°C the expected lifetime extends to 8,000 hours. At 45°C, lifetime increases to 32,000 hours. Every 10°C reduction approximately doubles the lifetime.
For maximum lifetime, operate at lower temperatures with voltage derating.
What voltage derating is recommended?
For this 80V rated capacitor, the maximum recommended operating voltage is 64V (20% derating). This provides good reliability margin. For critical applications, 50% derating to 40V provides even better reliability.
Design for 80% voltage derating for good reliability.
What is the ESR of the SF-22000uF-80V?
The Equivalent Series Resistance (ESR) at 100Hz is approximately 0.025 Ohm. This very low ESR provides excellent filtering performance and minimizes self-heating even at high ripple currents. For detailed specifications and application support on capxon SF-22000uF-80V, refer to the datasheet or contact our team.
For applications requiring even lower ESR, consider the SM low-impedance series.
Can multiple SF-22000uF-80V capacitors be used in parallel?
Yes, multiple capacitors can be connected in parallel for extremely high capacitance requirements. Two capacitors provide 44000uF and can handle 24A ripple current. This is common in very high-power applications. Use symmetrical layout for balanced current sharing.
For very high-power applications, use parallel connection.
What are the physical dimensions and mounting requirements?
This capacitor has a diameter of 35mm and length of 60mm. The snap-in terminals have 7.5mm spacing. Ensure adequate clearance for the large capacitor body and consider mechanical support for the weight. Thermal management is important due to the high ripple current capability.
Verify mechanical fit and ensure proper thermal management for your application.
