ClarityCap ESA 0.68µF 250VDC 3%

The ESA range has been developed as a direct result of the 2 year research programme conducted between ClarityCap and the world renowned Acoustics Research Centre at the University of Salford.

The performance of the ESA capacitors has been dramatically enhanced by reducing resonant sonic outputs from the capacitor winding itself. This is achieved by careful selection of the highest quality polypropylene base film combined with thick pure aluminium metallisation and close control of critical production processes. The resulting ESA range offers exceptional performance in audio applications at 250Vdc.  A guaranteed 3% tolerance ensures component to component consistency for a balanced system and reproducibility across production runs.

As with all ClarityCap products tape and resin colours are flexible. Unless otherwise specified ESA capacitors are supplied with silver tape and black resin.
