FPCAP has excellent frequency characteristic nearly equal to the film capacitor.
Using the high conductivity of the Functional polymer with an electrolyte, and adopting the
winding element for layer thinness of electrolyte, the ESR is improved greatly and has the
frequency characteristic that is nearly equal to the film capacitor.

The temperature dependence of the FPCAP is that it features little change in
temperature for the ESR.
Since ESR is dominant at high range of impedance (near resonance point),
the ESR value greatly affects Noise clearing capacity.
What ESR changes little against temperature means that Noise clearing ability
changes little against temperature as well.
