Flattened metalized film wound capacitor, case mold type capacitor using the same, inverter circuit, and vehicle drive motor drive circuit

摘要

A metalized film capacitor capable of exhibiting stable performance in a wide temperature range is provided. The metalized film capacitor has an elliptical cross sectional shape having a major axis of 60 mm or above. In this capacitor, offset (107) for shifting in the width direction of a pair of metalized film (103) is set to 1.2 mm or above. Since the bonding state between metal vapor-deposited electrode (102) and metal sprayed electrode (106) formed on the end surface is stable, a stable contact state between metal sprayed electrode (106) and dielectric film (101) is maintained, thereby preferably maintaining tan´ and exhibiting excellent performance even if the use temperature range is increased and the thermal stress is increased.
