Capacitor with improved heat dissipation

The capacitor comprises: a first winding member, further comprising a first dielectric layer 42 and a first conductive layer 39; a second winding member, further comprising a second dielectric 37 layer and second conductive layer 40; where the first winding member is interleaved, partially or entirely, with the second winding layer; a dielectric package 12 is adapted to at least radially contain or border the first winding member and the second winding member; a first 54 and second 56 metallic members which are generally planar, radially extending surfaces for electrically and mechanically contacting an upper portion the first conductive layer 39 and a lower portion of the second conductive layer 40, respectively; and a first lead 22,24 coupled to the first metallic layer 54 and extending through an upper side surface of the dielectric package 12.
