  • Example 2 As shown in Table 2, the results of the applied voltage boosting test and the accelerated life test were not preferable in Comparative Example 1, and the results of the accelerated life test were not preferable in Comparative Example 2. Further, in Comparative Example 3, the results of the applied voltage boosting test and the accelerated life test were not preferable, and in Comparative Example 4, the results of all the tests were not preferable. Compared with Comparative Example 1-4, each of Examples 1-4 obtained stable and good results in each test. In particular, Example 3 gave the best results in most of the tests (other than the 500 hour accelerated life test).
  • the metallized film of the present invention can be used for various metallized film capacitors.
  • the metallized film capacitor can be used for the following various purposes. That is, (1) mobile terminals (mobile phones, portable music players, smartphones, tablet terminals, wearable devices, etc.), (2) personal computers, (3) digital cameras, (4) home appliances (TVs, DVD recorders, refrigerators, etc.) Washing machines, air conditioners, etc.), (5) Car navigation, (6) Power conditioners for power generation (solar, wind power, etc.), (7) LED lighting, (8) Automobiles (electric vehicles, hybrid vehicles, plug-in hybrid vehicles, etc.) ), (9) Rail vehicles, (10) Construction machinery, (11) Industrial equipment, (12) Other various inverters, and the like. Above all, it can be used for capacitors used in automobiles and electric power applications that require high frequency characteristics.

Abstract

L'invention concerne un film métallisé comprenant un film diélectrique. Sur le film diélectrique, sont formées une partie d'introduction d'électricité, une marge isolante et une partie d'électrode située entre la partie d'introduction d'électricité et la marge isolante. La partie d'électrode est divisée en une grande partie d'électrode, une première partie d'électrode divisée, une deuxième partie d'électrode divisée et une troisième partie d'électrode divisée qui sont agencées en ordre avec une partie de marge entre celles-ci depuis la partie d'introduction d'électricité vers la marge d'isolation. La grande partie d'électrode est connectée à la première électrode divisée par l'intermédiaire d'un premier fusible. La première électrode divisée est connectée à deux deuxièmes électrodes divisées par l'intermédiaire d'un deuxième fusible unique. Les deuxièmes électrodes divisées sont connectées à deux troisièmes électrodes divisées par l'intermédiaire d'un troisième fusible unique.
