Title:
LAMINATED CAPACITOR
Document Type and Number:
Japanese Patent JPH04139809
Kind Code:
A
Abstract:

PURPOSE: To improve withstand voltage characteristics and lifetime characteristics by making the vapor-deposited metal of one face electrode of a metallized film from aluminum and that of the other face electrode from zinc or zinc alloy.

CONSTITUTION: The vapor-deposited metal of a metallized film 3 uses an aluminum material for one face electrode 1 and zinc or zinc alloy of restricted thickness of vapor-deposited film for the other face electrode 2. That is, the vapor- deposited metal of one face electrode 1 is aluminum of excellent characteristics of self-recovery action, and that of the other face electrode 2 is zinc or zinc alloy; thinning its thickness of vapor-deposited film causes the action of electric self-recovery to work effectively in a cut face, and withstand voltage characteristics in a cut face to approximate those of a dielectric film itself. This can provide a laminated capacitor excellent in withstand voltage characteristics and voltage acceleration lifetime characteristics.
