Standard Z-Cap

The Standard Z-cap is an axial-type capacitor made from metallized polypropylene and specifically manufactured for audio applications.
Special attention to winding technique has resulted in enhanced control of microphonics which allows the Standard Z-Cap to outperform many higher priced competitor products.

400Vdc Tolerance 5% But typically measure under 3%

Jantzen Capacitors and Foil / Signal direction.

All Jantzen crossover capacitors are non-polarised. This means they can be wired in either direction without any harm.

Some believe that capacitors do exhibit improved sonic character when the signal enters the end with the inner foil.

For the Superior, Silver, and Alumen Z-Caps the inner foil end is always to the left (When reading left to right).
So the signal 'in' would be from the left (inner foil), and 'out' would be to right (outer foil).

For the Cross-caps and Standard Z-caps the inner and outer foil changes from production batch to production batch.
So without individual testing there is no way to know which is the 'in' or 'out' lead.
