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.
