When the concept "Fast Capacitors" was first introduced in late 1987, SOLEN Inc. was the first capacitor design company in the world to apply this radically new advanced design concept to metallized polypropylene film capacitors for audio application. It was a challenge for SOLEN to put this much advanced design refinement and breakthrough engineering into film capacitors that shatters the boundaries between ordinary film capacitors and fast film capacitors.
Advanced design concept
This advanced design concept was originally developed for the European Space Agency for very high pulse current power-electronics, where many Kamps, Kvars or kV/µs needed to be accommodated, such as radar pulse modulators and power-factor correction banks. Extensive research and development, applying the latest developments in aerospace technology to the plastic film capacitors manufacturing process and equipment, have led us to the successful design and development of "SOLEN Fast Capacitors."
Fast Capacitors
The "SOLEN Fast Capacitors" consist of highest grade aluminum metallized polypropylene film available. The fast capacitors are the round wounded type, tubular "square" shape. They use an extended bifilar thicker aluminum metallized high quality polypropylene film electrode construction type. The face ends of the winding are thermal arc metal sprayed with pure zinc to connect all the turns in parallel to obtain the lowest inductance. Lead connections are made by means of welding a high purity large diameter tinned oxygen free copper's leads onto the metal spayed face ends for high current capacity. The windings are then enclosed without impregnation in reinforced plastic tape wrapping with an epoxy resin sealed ends.
Electrical performance
This superior concept significantly improved the electrical and mechanical characteristics of the capacitors. They deliver a high level of performance that has never before been achieved, which will directly enhance the efficiency of loudspeaker and other electronic equipment. SOLEN Fast Capacitors outperform any other similar capacitors: multi-sections, segmented, ordinary or otherwise, due to our unique short length, a wide diameter, fast design. It is as simple as that. fast design.
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, unrivaled 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.
Sonic performance
The SOLEN Fast Capacitors exhibit near-zero losses, they reduce linear, nonlinear distortion and phase distortion to unmeasurable level, showing an almost unbelievable ideal capacitance reactance curve which give the highest level of signal resolution. They literally disappear, they are a step across the boundary of an ordinary capacitor, they make you experience for the first time the visionary world of "real music," it is a masterpiece beyond a capacitor, they make the incredible audible.
