All of our metallized film capacitors use the maximum lowest possible resistivity metallized layer for a given
film thickness which is vacuum deposited on a biaxially oriented polypropylene film.
The FAST CAPACITOR ™ concept is mainly obtained by decreasing the film width from the standard round
tubular winding type configuration to a shorter FAST tubular “square aspect ratio” round winding type which decrease
the winding resistivity and also increase the contact area.
The decrease of the film width will decrease by the same percentage the resistivity of the winding and the
capacitor transit time, hence the name “FAST”. The increase of the contact area of the winding ends will increase by
the same percentage the current carrying capacity.
These two main factors, lower winding resistivity and larger contact area will decrease, by a measurably
large amount equal to the “Performance Improvement” percentage, the Equivalent Series Resistance and the
Dissipation Factor of the capacitor.
This superior concept significantly improved the electrical and mechanical characteristics of the film
capacitor. They deliver a high level of performance that has never before been achieved, which will directly enhance
the efficiency of any electronic or electrical equipment. SOLEN polypropylene metallized FAST CAPACITOR™
outperform any other similar capacitors: multi sections, segmented, oval, stacked, ordinary or otherwise, due to our
unique short length, large diameter, FAST design. It is as simple as that.
They have lower dielectric absorption factor, lower equivalent series resistance, lower inductance, higher
resonant frequency, more linear impedance, lower dissipation factor, higher current capacity, faster rise time,
unrivalled handling of fast high current pulse, high temperature stability, excellent long term electrical and mechanical
reliability and a better damped mechanical self resonance under dynamic signal conditions.
Consequently, the SOLEN FAST CAPACITOR ™, for instance, represents an astonishing leap forward in
capacitor design and engineering standards.
SOLEN, the Film Capacitors against which ultimately all the others must be judged.
