Capacitor Jantzen Audio Alumen 0,47uF / 100VDC / 5% / PPT / Aluminum Foil Cap / 17x44mm

The Jantzen Audio Alumen Z-Cap (pure aluminum foil capacitors) was especially designed for the tweeter and mid-section of crossovers for passive hi-fi speakers. 

The improved transparency performance of this new cap is on the same high level as our SilverGold Z-Cap, but with a slightly softer tonal presence and less  brightness / sheene / glare in comparison.


The Alumen Z-Cap will offer a more “neutral” presentation in the overall sound in certain crossover designs, and by “neutral” we refer to the focus will be shifted from what can be a somewhat overemphasized brightness from a Super PP cap, being replaced with a more even balance between the depth of the midrange and the presence of the tweeter.

Due to the lower voltage rating, we advice customers to be mindful when using Alumen & Amber Z-Caps for tube- 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).
