DC Link Capacitor Product Data Sheets

Metallized Polypropylene DC Link Capacitors

The Electrocube 959A series is a rugged non-inductively wound metallized polypropylene DC link capacitor. It is ideal for high current power inverter applications which require long life under extreme operating conditions such as EV power conversion, aircraft power systems, battery chargers and other high pulse applications. The 959A series is an excellent replacement for electrolytic capacitors and is manufactured in a high impact polymer case for insulation and durability.
