DC capacitors with autonomous safety mechanism

The special kind of films and coating patterns used in our oil-filled E63-capacitors give them a high specific ratio of capacitance to volume and makes them extremely overvoltage proof.

Very good self-healing characteristics and the integrated autonomous overpressure protection ("BAM") ensure safe operation and controlled disconnection in the event of overload or failure at the end of operating life. Hence the E63s are interesting particularly for applications with high AC ripple currents, e.g. as smoothing or supporting capacitors in buffer storage circuits, and in sensitive environment with high safety requirements.

Note that the presence of an overpressure mechanism adds substantially to the self-inductance of the capacitor, and limits the surge current rating. If self-inductance and surge current are important issues, then our ranges E50, E51, E60, E61, E66, E67, E53 or E55 may be considered as a more adequate option.
