Abstract
A metallized film capacitor includes a dielectric film and two metal vapor-deposition electrodes facing each other across the dielectric film. At least one of the metal vapor-deposition electrodes is made of substantially only aluminum and magnesium. This metallized film capacitor has superior leak current characteristics and moisture resistant performances, and can be used for forming a case mold type capacitor with a small size.
Claims12
A metallized film capacitor comprising:
- a dielectric film;
- a first metal vapor-deposition electrode provided on an upper surface of the dielectric film;
- a second metal vapor-deposition having an upper surface facing a lower surface of the first metal vapor-deposition electrode across the dielectric film;
- a first electrode connected to the first metal vapor-deposition electrode;
- and
- a second electrode connected to the second metal vapor-deposition electrode, wherein
- at least one metal vapor-deposition electrode of the first metal vapor-deposition electrode and the second metal vapor-deposition electrode is made of substantially only aluminum and magnesium.
