Capacitor Foil

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.
