High Voltage AC/ DC Capacitor finds application in power electronics in general, and in low inductance buffer circuits with higher voltages as well as in discharge circuits. The Capacitor comes filled with oil. The Capacitor has good ratio of capacitance to volume and has high pulse strength and good self-healing characteristics without loss of capacitance. The High Voltage AC/ DC Capacitor is offered without safety mechanism and can be laid out and rated in such manner that partial dielectric discharges and consequential risk of failures in the users application are reduced to a minimum.
