Filtering Capacitors

Filtering
Filtering

AC- or DC-filter capacitors, connected line-to-ground, are intended to filter high frequency components generated by the power electronic converters.

Filter capacitors are compliant with the standard IEC 60358-3 and are available with either a porcelain or a composite insulator that is in full compliance with IEC 60815.

The filter capacitors are designed for a wide range of service temperatures. Recently, “arctic” capacitors have been designed for applications in the most severe environmental conditions, supporting extreme temperatures down to –60° Celsius.

CONDIS®’ technology is highly flexible and can be customized to meet customers’ specific mechanical and electrical requirements.
