Our Superior and Silver Z-Cap Capasitors are an axial type made of metallized polypropylene, especially manufactured for audio purposes.
The materials we use, were chosen for the best sonically results in this price class.
We use a special machine to wind all our capacitors, so that the capasitors become a very tight reel. This minimizes the inner vibration and keeps microphonic effects as low as possible.
The capacitors are available in a wide range of capacitance values with low tolerance.
The Superior and Silver caps are all protected against high humidity.
Finally, both capacitors are state of art in their price class!
NB! All our Superior and Silver Z-caps will show the true picture immediately, so they do not need any burn in time.
Superior Cap.
0,1 uF - 0,33 uF AC value of the voltage rating 1200 VDC / 600 VAC
0,47 uF - 22 uF AC value of the voltage rating 800 VDC / 425 VAC
Silver Cap.
0,1 uF - 0,33 uF AC value of the voltage rating 1200 VDC / 600 VAC
0,47 uF - 22 uF AC value of the voltage rating 800 VDC / 425 VAC

Technical info and specifications for Z-cap Superior and Z-cap Silver:
All our Superior Caps have high grade copper lead wire to secure the excellent qualtity of these caps.
All our Silver Caps have pure silver lead wire to secure the extreme high quality of these caps.
We have succeeded to minimize the inner inductance and to produce a fast sounding capacitor via our skilled technique.
The capacitor windings are interleaved, so the inductances effectively cancel each other out.
these two windings are connected in series. This means, it takes two 2uF windings to make a single 1uF capacitor.
This is equal to produce one full 4uF capacity using conventional technology.
Technical Specifications:
Dielectric: Polypropylene
Tolerance: 1% - 2%
Loss angle tan = 0.00002 to 1K
Loss angle tan = 0.00001 to 10K
