Metalized film 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 for shifting in the width direction of a pair of metalized film is set to 1.2 mm or above. Since the bonding state between metal vapor-deposited electrode and metal sprayed electrode formed on the end surface is stable, a stable contact between metal sprayed electrode and dielectric film is maintained, thereby preferably maintaining tan &sgr;and exhibiting excellent performance even if the use temperature range is increased and the thermal stress is increased.
