Duelund JDM Pure Silver Capacitors

Available in either 100Vdc or 600Vdc rating, The Duelund JDM Pure Silver Foil capacitors are now fully equipped with the Jensen winding and impregnation machines. JDM stands for Jensen Domestic Market, a nod to the recently closed Jensen capacitor manufacturing company that Duelund worked so closely with.

The JDM Silvers are suitable for speaker crossovers, signal electronics, and bypass capacitors. The 100Vdc metal foil capacitors with WPIO paper dielectricum for loudspeaker use only.

They are constructed with wax paper in oil dielectricum, previously reserved for their top-of-the-line CAST series. The paper separating the silver foils are vacuum impregnated in a deep vacuum 100 times lower, than what was possible at the old factory. Following this, the windings are also wax-impregnated to help seal the winding completely. This formula makes an incredibly robust high-performing capacitor at an amazing price, considering they are constructed from silver foil.

The outer material is made from paper, which the capacitor wind sits within, it is further potted inside using the same material as their CAST models. 

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, generally the signal output.
