- Low leakage current
- High lifetime performance
Construction
Wound Capacitor
Layer structure
![The aluminum foil of the anode is formed by anodic oxidation before the winding process, so that the dielectric (oxide layer) is strengthened. The winding is impregnated with a monomer. The highly conductive polymer is formed by polymerisation. The paper interlayer ensures an even structure and a defined distance between the anode and cathode foil.](/components/media/o744608v558%20cm-inner-structure-hybrid-polymer-caps.png)
