AVX Corporation has developed a power film capacitor series specifically for DC filtering applications. The FFLI series advanced power film capacitor has a life expectancy of 100,000 hours, and unlike aluminum electrolytic devices, the FFLI series devices employ controlled self-healing where end-of-life is simply defined as the time taken for the capacitance to lose about 5 percent of its nominal value.
The FFLI series power film capacitors feature capacitance/voltage ratings of up to 3000 μF and 1900 VDC/100 Arms. Additionally, they can operate in temperatures up to 95°C. Qualified to IEC 61071 for power electronic capacitors, the FFLI series also meets IEC 60068-1 environmental testing requirements and IEC 61373 shock and vibration requirements.
