Kemet Slit Foil Electrolytics

Conventional capacitors, being made of large, coiled, thin strips of aluminium, are prone to induce eddy currents across their conducting surface. These currents prevent the capacitor from doing its job optimally, thus degrading subjective sound quality. By introducing a series of tiny slits in the foil conductors these eddy currents are dramatically reduced, therefore, improving the subjective and measured performance.

Modern electrolytic capacitors are designed for use in power supplies so most aspects of their design have been optimised. Some of the advances in the design may not be beneficial in audio applications where the requirements of the capacitors are very different.

Slit foil capacitor research has also indicated that improvements in the general construction of the capacitors give better results in audio where the fidelity of the wave shape is very important. Great attention has been paid to the construction details which can affect the performance, i.e. foil type, its connections and mechanical construction.

Please note BHC are now owned by KEMET and the new range we have in is labelled KEMET. Rest assured these are the same design slit foils as the original BHCs.

The Kemet Slit Foil Electrolytics is also a replacement for the Supertech 2T Slit Foil Capacitors.
