ClarityCap CSA Capacitors

Building on the success of the popular range of ESA capacitors from Clarity Cap they have launched the all new CSA range. They are constructed using the same winding method as the ESA, manufactured from polypropylene film the component is supplied in the familiar wrap and end seal style, wrapped in a polyester tape and encapsulated in an epoxy resin. However, the CSAs differ in how the lead outs are joined to the capacitor electrodes.

Connection of capacitor electrodes to the leads has always relied on thermal arc spray of tin-zinc, which results in hundreds of thousands of oxidised grain boundaries introducing; distortion and phase shifts at boundary crossings and increasing propagation impedance with diameter. CopperConnect technology introduces an embedded copper lattice to the end connection, dramatically reducing grain boundary crossings and signal path resistance, freeing capacitor designs achieve new levels of audio performance. CopperConnect technology dramatically reduces grain boundary crossings in the end connection and enables designs to employ narrower films for reduced capacitor ESR without introducing the corollary increase in end connection impedance. The philosophy of eliminating as many crystal boundaries as possible is extended to the use of premium grade 1.0mm2 tinned oxygen free copper leads. We are confident you’ll agree ClarityCap’s commitment to innovation has once again raised the bar for audiophile film capacitor performance.

They are available in both 250Vdc and 630Vdc ratings.
