Standard range or special design? Large capacitances right as you will.
Thanks to the special kind of films and coating patterns used in our E59-capacitors, clever winding geometries and refined internal construction, they unite large capacitance, very small self-inductance and high surge current sustaining capability (up to 1000kA) as well as the possibility of high rms currents (up to 1400 A). Instead of flat pack windings, our capacitance is formed by compact cylindrical windings, avoiding the mechanical stress and instabilities at the edges of flat packs.
Special terminals allow for additional reduction of the self-inductance. At the same time, they are extremely overvoltage-proof. They are especially suited for buffer storage circuits of converters, filter circuits and such like.
The capacitors are housed in aluminium or steel cases and filled with solid resin which makes them absolutely dry and leakage-proof. Their shape and dimensions can be adapted to the individual requirements of our customers.
Even at high operating temperatures, and after numerous self-healing dielectric breakdowns, the capacitance remains stable.
An irreversible pressure switch can be used for external monitoring of the internal pressure. It signals 0.5 atmospheres of pressure rise by closing (or optionally: opening) the contact, allowing for safe external disconnection in the event of overload or failure at the end of operating life.
Ranging from 250 mF 500 V DC to 100 µF 25,000 V DC, AC voltages up to 17,000 V AC; exact ratings depending on customer specifications.
