Based on our proprietary metallizing capacitor films, we provide a range of high voltage capacitors in self-healing technology, using special metallizing patterns.
Despite the high voltage ratings, these can be made in dry technology and without expensive bushings. For optimized self-inductance, they are made without safety mechanism; by using a clever internal design they can be laid out and rated in such away that partial dielectric discharges and consequential risk of failures in the customer's application are reduced to a minimum.
The all in one; high RMS and surge currents combined with low self-inductance is done by using sophisticated metallizing patterns, special sinusoidal dual slitting technology, and clever winding geometries.
The low series resistance version provides high pulse strength and is especially suited for the damping of GTO thyristors and low-inductance buffer circuits with high RMS currents. Their very low self-inductance makes them also suitable for use in high-current applications with medium frequencies. Along with their very good ratio of capacitance to volume, these capacitors have high pulse strength and very good self-healing characteristics without loss or shift of capacitance.
A series, which are very similar in design and electrical features, have been optimized particularly for large capacitances at high operating voltages. These are housed in flame-retardant plastic cans (V0) and filled with solid resin. Special care has been taken both in terms of design and conservative electrical rating, to ensure reliable operation even under tough environmental conditions. Connection is usually made through robust axial terminals with internal thread. If needed the same construction is available for radial connection through robust studs with M8 thread, providing two brackets at the base of the can which make for convenient mounting.
