Filter Capacitors

AC- or DC-filter capacitors, connected line-to-ground, are intended to filter all high frequency harmonics due to power electronic converters.

Filter capacitors are compliant with standard IEC60358-3; they are available with a porcelain or a composite insulator. All standard insulators are equipped with single or alternating long-short sheds and are in full compliance with IEC 60815.

The filter capacitors are designed for a wide range of service temperature. The mixed dielectric in the capacitor element allows for a very stable capacitance value over the whole temperature range.

In a recent addition to the filter capacitor product range, "arctic” capacitors have been designed for applications in the most severe environmental conditions, supporting extreme temperatures down to –60 degrees Celsius.

Maxwell CONDOR technology is highly flexible and can be customized to meet customers’ specific mechanical and electrical needs.
