Composition research for capacitors with increased capacity
UACJ Foil develops technologies such as trace component and cube orientation control technologies that realize highly pure aluminum foil with excellent etching characteristics. This allows for manufacture of aluminum electrolytic capacitors with improved capacity and performance.
High-voltage anode foil
UACJ Foil meets customer needs by developing high-capacity foil. This is achieved through microstructure and surface shape control of highly pure aluminum foil controlled for ppm-order trace components.
Trace component controls
Surface concentration element controls
Surface film characteristic controls
