Jupiter Copper foil Series
Paper and wax foil Capacitors



The new Jupiter Copper foil capacitor is the latest development from Jupiter Condenser. The Jupiter Copper is an all new design. As you may have guessed, it uses pure Copper foil. The capacitor retains the annealed 20ga solid Silver leads which are used on all the HT and Flat Stack designs. These have been years in the making. Everything has been evaluated from particulars regarding the foil, tightness of winding, paper, waxes and even which solders. Feedback from beta-testers has been very good. They seem to have all the benefits of the HT with "more" richness and musicality. Considering the price, this capacitor is a sure winner!

Jupiter Copper foil paper and wax capacitors.

Jupiter Condenser Co. Copper Foil capacitors are a large plate area cap specifically designed for audio applications. Each capacitor is precision wound of the finest USA materials and is carefully constructed entirely by expert hands.
We believe the dielectric is the first area to be addressed in capacitor manufacture. Since the early 1900's to the late 1940's paper capacitor research was focused in the area of dielectrics, there was no mention to foils. Paper formulation and it's handling were key, though impregnants were considered fundamental and anti-oxidant characteristics of impregnants were prized. Thus we began our research on improving impregnants first, then improving the properties of the paper itself. Beeswax naturally contains small amounts of propolis, which is a very powerful anti-oxidant, other properties include: anti-bacterial, anti-fungal, and anti-viral. Propolis protects the paper and foil from oxidation and degradation.

Jupiter caps are designed for use in high quality high definition audio signal circuits. From tube gear to solid state, more users can enjoy the benefits of their natural high definition sound.

The "new look" to Jupiter Condenser Co. capacitors, is true to form following function. Not just a new style, the outer casing is still true to natural materials yet offers improved environmental characteristics. A paper tube impregnated with phenolic resin assures excellent moisture resistance along with a resin end fill to lock moisture out. The casing material will not melt or drip even at higher temperatures.

Regarding capacitor section processing...... a refined impregnation system* is utilized, capable of deep vacuum and high pressure. Vacuum pressures well below 10 millitorr are achieved, and even higher positive pressures assure consistent impregnation with more gas and moisture removal. New proprietary measures of strengthening dielectric properties have been developed and employed which yield higher insulation resistance and allow greater operating temperatures. Wax and paper construction yields a very well mechanically damped capacitor, free from electrostatic and mechanical ringing.

*The computer controlled wax vacuum impregnation system was engineered and built by Jupiter Condenser, and section processing is based on techniques developed by Western Electric and RCA.

Application Notes:

For best results keep capacitors as cool as possible, use common sense. Do not place next to or touching hot resistors or under-chassis signal tubes that get hot etc. This is good practice to follow with any capacitors, especially paper capacitors. Generally for every 10 degree C increase, component life is diminished by half.
