Frequently Asked Questions
What is the maximum ripple current for the KF-2200uF-16V?
The rated ripple current is 2.0A at 85°C and 120Hz. This high rating makes it suitable for demanding applications. At lower temperatures, the capacitor can handle higher ripple currents - approximately 2.4A at 65°C.
For applications exceeding 2.0A ripple current, consider using multiple capacitors in parallel.
What is the expected lifetime of the KF-2200uF-16V?
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 16V rated capacitor, the maximum recommended operating voltage is 13V (20% derating). This provides good reliability margin. For critical applications, 50% derating to 8V provides even better reliability.
Design for 80% voltage derating for good reliability.
What is the ESR of the KF-2200uF-16V?
The Equivalent Series Resistance (ESR) at 100Hz is approximately 0.08 Ohm. This low ESR provides good filtering performance and minimizes self-heating. The ESR decreases with increasing temperature. For detailed specifications and application support on capxon KF-2200uF-16V, refer to the datasheet or contact our team.
For applications requiring lower ESR, consider the KM low-impedance series.
Can multiple KF-2200uF-16V capacitors be connected in parallel?
Yes, multiple capacitors can be connected in parallel to increase total capacitance and share ripple current. Two capacitors in parallel provide 4400uF and can handle 4.0A ripple current. Use symmetrical layout for balanced current sharing.
For very high capacitance requirements, use parallel connection.
What applications is the KF-2200uF-16V best suited for?
This capacitor is ideal for: 12V power supply output filtering, energy storage for hold-up time, audio amplifier power supplies, and industrial control systems. The high capacitance provides excellent smoothing and energy storage capability.
Use for applications requiring high capacitance at low voltage.
