Jupiter HT Flat Stacked Paper Beeswax Cryo (Discontinued)

Jupiter HT Flat Stacked Paper Beeswax Cryo Capacitors

Jupiter Condenser has applied the same materials and processes used to make their successful HT line of capacitors to make there all-new Flat Stacked capacitors. They feature a reinforced beeswax paper dielectric and (with further improved impregnation techniques) and cased in a non-drip/melt casing and can withstand higher operating temperatures. The Flat Stacks offer a high DC voltage rating, 1uF to 4.7uF at 600Vdc and 300Vdc on capacitance above 4.7uF. It can be used as decouplers in valve amplifiers and in loudspeaker crossovers.

For productions, a 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. This is capable of deep vacuum and high pressure, providing 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 labeled end indicates the outermost foil and should be connected to the lowest impedance path to ground.
