Duelund Coherent Audio CAST-PIO-CU-AG-630-0,33 0.33 µF 2% 630 V CAST Paper in Oil Copper-Silver Capacitor
The CAST series represents Duelund Coherent Audio’s top-line approach to audio capacitors. Built around the Virtual Stack Foil principle, this design uses carefully arranged metal foil construction to reduce losses, distortion and microphonics, helping preserve clarity, tone and realism in demanding audio systems.
The CAST paper-in-oil construction uses Duelund’s proprietary WPIO dielectric impregnation process. Several days of high-pressure impregnation create strong damping characteristics, while the casting process and hard-pressed paper ring further improve mechanical stability. This makes the capacitor especially well suited to precision crossover components where vibration control and consistency matter.
This capacitor can be used in a range of audio applications, including crossover networks, signal coupling, bypassing and filtering. It is suitable for use in speakers, amplifiers, preamplifiers, DACs, CD players and other high-quality audio circuits where a natural, accurate presentation is the goal.
Duelund DCA16GA wire lead-outs are used for connection. The outer lead-out, positioned closest to the capacitor edge, is connected to the outer foil and should be connected to the lowest impedance path to ground for optimal implementation.
