High voltage AC film capacitor for power electronics

Short Description:

Film capacitors used for AC/DC power converters and inverters.

The self-healing, dry-type, capacitor elements are produced using specially profiled, segmented metallized PP film which ensures low self-inductance, high rupture resistance and high reliability. Over-pressure disconnection is not considered necessary. The capacitor top is sealed with self-extinguishing eco-friendly epoxy. Special design ensures very low self inductance.
