Overview

Jantzen Audio 3.9uF 800V Silver Z-Cap Crossover Capacitor

Product Features

  • Dimensions: (Ø 30mm - L: 57mm)
  • Where the Superior Z-Cap is made with pure copper lead-wires, the Silver Z-Cap is made with pure silver lead-wires, changing the sound characteristics of the capacitor slightly.
  • Highly recommended for tweeters and mid-range application for high-end passive speakers and as coupling capacitors in tube and power amplifiers.
  • The Silver Z-Cap is a metalized polypropylene foil capacitor but made as special construction we call a “Super MPK Capacitor”.
  • Super MKP capacitors are made with a double lane of metalized polypropylene foil, hence a double foil construction.

  • By using special winding machines and winding techniques, two capacitors are connected in series within one capacitor housing,
  • When making this type of capacitor you therefore need 4 times the foil used in standard type metalized polypropylene foil capacitors.
  • Compared to standard type metalized polypropylene foil capacitors, the Superior Z-Cap is on a higher audiophile level, where even finest nuance improvements can be heard.
  • An extremely well made and precise MKP capacitor with a tolerance on capacitance of only +/- 2%.
  • Jantzen does not fill their capacitors with any dielectric fluid, which eliminates all risks of evaporation or leakage that can shorten longevity and quality of the capacitor.
