Duelund CAST Capacitors
The Duelund CAST Capacitor is their no holds barred flagship capacitor.
The construction builds on the foundation of our Virtual Stack Foil design but does so with the addition of a proprietary WPIO dielectricum which necessitates several days of impregnation under high pressure.
This creates a form with incredible damping properties giving a mechanical stability hitherto unheard of.
On top of this casting process, a ring of hard-pressed paper strengthens the damping properties of the design helping music flow effortlessly.
The Duelund CAST capacitor is available for speaker use and as the CAST 630v for DC-applications. Available as pure copper or pure silver.
The outer lead out, closest to the edge of the capacitor, is connected to the outer foil and as such should be connected to the lowest impedance path to ground.
The Duelund CAST capacitors
are designed for speaker use, they are rated up to 200 Volts DC and are available in:
Copper - CASTCU (0.1uF to 40uF)
Silver - CASTAG (0.1uF to 8.2uF) Please ask us for a quote on this range
The Duelund CAST DC capacitors
are for signal applications in amplifiers and pre-amplifiers. The cylindrical shape is standard with this design, however, Duelund recognizes that these can be difficult to fit in amplifiers so they make an optional BLOCK design, see "PICTURE" link below. Please let us know if you want this design as they have to be ordered. They are rated at 630 Volts DC and are available in:
Copper - CASTDCCU (0.22uF to 2.2uF)
Silver - CASTDCAG (0.1uF to 2.2uF) We do carry stock of the 0.1uF, 0.22uF, 0.47uF and 1uF
FREQUENTLY ASKED QUESTION
What is the difference between the VSF, VSF Black and CAST capacitors?
VSF is a wax/paper design with pure foil in either aluminum, copper or silver.
VSF black is the same, but an outer coating reinforces the already excellent damping of the VSF in order to better preserve low level detail and dynamics.
CAST is the no holds barred, with a wax oil hybrid paper dielectricum helping to dampen resonances far beyond the VSF design.
