The Duelund JDM Pure Copper Foil capacitors are new off the production line at the newly revamped Duelund Factory. 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.

They are constructed with wax paper in oil dielectricum, previously reserved for their top of the line CAST series. The paper separating the copper 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 copper foil. The outer material is made from paper, which the capacitor wind sits within, it is further potted inside using the same material as the CAST models.
