  • Jantzen Audio 4.7uF 100V Alumen Z-Cap Aluminum Foil Capacitor

Overview

Product Features

  • Dimensions: (Ø 17mm - L: 44mm)
  • The Alumen Z-Cap is a high-end pure aluminum foil capacitor, designed specifically for passive crossovers (tweeters and midrange drivers).
  • It utilizes a much thinner dielectric insulation compared to the market standard.
  • A high voltage rating is not needed for application related to passive loudspeaker crossovers.
  • The usage of a thinner dielectric insulator allows for a capacitors with less “memory” and one that is much faster reacting.
  • The Alumen Z-Cap offers unparalleled value for money in terms of cost versus performance.
  • Compared to the Superior and Silver Z-Caps (Super MKP / double metallized polypropylene foil) capacitors, the Alumen Z-Cap will bring less brightness and a little more natural top end balance to your system.
  • Ideal for audio aficionados who prefer a slightly less bright system, while also hearing improvements in the overall naturalness/neutrality of the whole system.
  • Due to the max. 100 volts DC voltage rating, we advise customers to be mindful when using Alumen Z-Caps for tube/valve and power amplifier application.
  • For upgrading the coupling capacitors in amplifiers, we instead recommend choosing our Superior or Silver Z-Caps (Double-foil Super MKP capacitors).
