Duelund Coherent Audio CAST-PIO-CU-AG-630-0,22 CAST Paper in Oil Copper-Silver Capacitor
The CAST-PIO-CU-AG-630-0,22 belongs to Duelund Coherent Audio’s CAST PIO capacitor family, developed for audio systems where tonal accuracy, clarity and natural reproduction are priorities. As a premium capacitor, it builds on the Virtual Stack Foil principle, a construction approach intended to reduce losses, distortion and microphonics.
The CAST process combines paper-in-oil construction with Duelund’s proprietary WPIO dielectric impregnation. This process takes several days under high pressure and creates a highly damped structure with strong mechanical stability. A ring of hard-pressed paper further supports the damping properties, helping the component perform consistently in demanding crossover use.
Duelund CAST capacitors are suitable for multiple audio applications, including crossover networks, signal coupling, bypassing and filtering. They can be used in speakers, amplifiers, preamplifiers, DACs, CD players and similar high-resolution audio equipment where transparency, dynamics and realism are important.
The capacitor uses Duelund DCA16GA wire lead-outs. The outer lead-out, closest to the edge of the capacitor, is connected to the outer foil and should be connected to the lowest impedance path to ground. This makes correct orientation straightforward during installation in carefully built audio circuits.
