Duelund Alexander Copper Foil Capacitors
The Alexander's are constructed out of pure copper foil, using a resonance-damping paper dielectricum; the whole capacitor is vacuum-impregnated with oil to ensure both longevity and further internal damping, resulting in a greater sonic benefit. They use the same oil that is used in their CAST series. The leadouts are silver-plated copper. With the launch of the Alexander, we now have an exciting alternative to the likes of Audio Note and Jensen.
Specifications:
- They are rated at 900V DC and have a tolerance of +/- 10%
- capacitance range is 0.0015uF to 3.3uF
- The leadout closest to the "D" in Duelund is connected to the outer foil, and as such should be connected to the lowest impedance path to ground.
If you are looking for a specific value, we have added a CAPACITOR FILTER to speed your search up.
IMPORTANT NOTICE
With the demise of Jensen and Duelunds's access to their machinery, Duelund can no longer produce the Alexander range of capacitors.
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.
This range has been discontinued, but we still hold a large quantity of stock. If you find a product is out of stock, please see the alternative product.
