Abstract
A metallized film capacitor is made by winding or laminating a both-side metallized polypropylene (PP) film and a non-metallized PP film. Limiting the heat shrinkage factor and the thickness of the PP films, the position of deposited electrodes, and the rate of the peeled area of the deposited electrodes to a certain range provides a metallized film capacitor having improved dieletric strength, tan δ, and charge-discharge characteristics.
