Duelund RS Loudspeaker 100Vdc capacitors

The all-new RS series from Duelund is a further improvement on their VSF line of capacitors. After many years of research and development, they decided to improve upon the original VSF by applying the elaborate manufacturing process used in making the CAST version. Using high purity copper foil with a wax impregnated dielectric and treating with their own anti-resonance CAST material the RS series was born.
These capacitors approach the CAST performance in a number of ways, but at a lower cost.
We are stocking both the 100Vdc Loudspeaker range and the 400Vdc Electronic range.

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 lead-outs are 1mm diameter annealed copper wire, tin-plated bare wire.

Please note that the original VSF line is still available for those that prefer.



With the demise of Jensen and Duelunds's access to their machinery, Duelund is no longer able to produce the RS range of capacitors. We do have some stocks left, just click BUY NOW.

However, Duelund is launching the all-new JDM and JDM CAST range. JDM is short for Jensen Domestic Market, a homage to the 100-year production legacy in Denmark that Jensen Capacitors stood for. The capacitor will be available in several pure metal foils and dielectrics, to cover pretty much all audio bases – be it for loudspeaker or electronics.

Standard sizes will be 0.001uF – 100uF, voltages rating will be low level to 600Vdc. With the JDM, their aim is to offer the ultra-high material quality Duelund is known for while leveraging the production power, they have available through the acquisition of Jensen’s production line. The net effect is, that they will offer a fully Danish made pure metal foil “wet” capacitor with premium materials sourced from Germany and Switzerland - at pricing we have never been able to before. The new range is available in Silver and Copper.
