Thanks to the special kind of films and coating patterns used in our E56/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 700kA) as well as the possibility of high rms currents (up to 750A). 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.

In modern applications of power electronics, AC capacitors are among the most critical links in the chain of components when it comes to long operating life, safety and reliability of operation. Decades of proprietary ELECTRONICON experience in metallizing capacitor films and designing high-end capacitors have created our very own Know-How, for instance in special metallizing patterns, our SINECUT slitting technology and optimized winding geometries. This enables us to design AC capacitors with a high specific ratio of capacitance to volume, high AC-voltage load capacity and outstanding suitability for high rms and surge currents. The cylindrical capacitors of our universal AC/DC series "E62" are perfect for non-sinusoidal voltages and pulsed currents, e.g. as damping or commutation capacitors switched in parallel to a thyristor, or connected in series with a resistor (damping of undesirable voltage spikes during the switching of power semiconductors).

The E62-3ph capacitors stand out by their high AC-voltage load capacity. They have been designed especially for heavy duty operation in extreme or sophisticated operating conditions, such as AC filtering and power factor correction in wind power and UPS applications, harmonic filtering in three-phase mains with high or unusual levels of harmonic distortion, a.m.o. Thanks to their construction, they have a very low series resistance and a small self-inductance. Our basic design principle - preferring short winding elements with comparably large diameters - as well as the use of wavecut technology in many models, serves for high rms and surge current strength. The three capacitor elements are connected in delta internally; the plant oil filling is environmentally friendly and serves for optimized heat dissipation and improved internal insulation.

The traditional ALLFILM system of conventional medium and high voltage capacitors consists of aluminium foil and polypropylene, immersed completely in synthetic, flammable oil. Breakdowns in this kind of dielectric tend to result in permanent short circuits which take out the entire capacitor element, change the voltage conditions inside the capacitor and initiate a chain reaction of further failures of capacitor elements which will end up in the loss of the entire capacitor. In three-phase capacitors, this process is usually accompanied by the occurrence of phase asymmetries which may cause damage and catastrophic failure. In our MSD™ medium voltage capacitors, we are using the metallised polypropylene so well known from LV power factor correction. Instead of flat pack windings, our capacitance is formed by compact cylindrical windings, avoiding the mechanical stress at the edges of the ALLFILM flat packs.

The winding elements in our MKP(D) capacitors are surrounded by poison-free vegetable oil. Like our premium ranges of MKPg and MKP, the MKP(D) combines the best possible technical features with eco-friendliness and operational safety, using special metallizing patterns, our SINECUT slitting technology and optimized winding geometries. Besides excellent ratio of capacitance to volume, our MKP(D) capacitors distinguish themselves by high AC-voltage load capacity and suitability for high rms and surge currents. Our MKP(D) are available as single and three-phase capacitors and well-suited for all conventional applications in power factor correction. They have a self-healing dielectric and are provided with an irreversible overpressure disconnector (break-action mechanism, " BAM "). Connection is made through convenient standard 6.3mm tab connectors. Technical layout, testing and application accord to IEC60831, UL810 and CSA 22.2.

With our long year know how and first-class production facilities, we are manufacturing capacitors in two basic technologies: MKP and MKPg™. In MKP capacitors, the winding elements are surrounded by poison-free vegetable oil, in MKPg™, capacitors, they are immersed by neutral insulation gas. When designing our product ranges, we focussed on the best possible technical features combined with eco-friendliness and operational safety, using special metallizing patterns, our SINECUT slitting technology and optimized winding geometries. Besides excellent ratio of capacitance to volume, our power capacitors distinguish themselves by high AC-voltage load capacity and outstanding suitability for high rms and surge currents. Unlike some of our competitors who proudly quote fantasy ratings, we have really tested our capacitors to their rated values, allowing for sufficient reserves and guaranteeing flawless operation within the specifications.

The PK16™ capacitor can be universally used for the assembly of low inductance DC buffer circuits and DC filters; with its high energy density it can replace banks of series-connected electrolytic capacitors as well as large film capacitors in rectangular cases. The capacitance in a DC buffer circuit must be sufficiently sized to both handle and smoothen the occurring ripple currents. The traditional use of series-/parallel-connected electrolytic capacitors offered large capacitance at seemingly low cost, however the low cost per microfarad is countered by the very low current strengh, the high sensitivity to voltage and current surges, as well as a substantial risk of failures in the field, resulting in high maintenance cost. Our advanced know-how in special capacitor film coating and many years of practical experience in designing and manufacturing capacitors have allowed us to develop our PK16™ range with high capacitance density.

In power electronics in general, and especially in low inductance buffer circuits with higher voltages as well as in discharge circuits, the call for capacitors with low inductance tends to pose problems: traditional high voltage capacitors are filled with oil, and the generous bushings required for clearance and creepage as well as internal safety mechanisms add substantially to the self-inductance of the capacitor. Based on decades of proprietary experience in metallizing capacitor films, ELECTRONICON has created a range of high voltage capacitors in self-healing technology, using the opportunities of special metallizing patterns. Despite the high voltage rating, our E51 range is manufactured in dry technology and without expensive bushings. Inside the can made of self-extinguishing plastic, the capacitor element is enclosed in solid resin (PUR). Connection is made through robust flat terminals with internal thread.

E53 and E55 capacitors have a particularly low series resistance and high pulse strength. Using sophisticated metallizing patterns, our SINECUT slitting technology and clever winding geometries, they are especially suited for the damping of GTO thyristors and low-inductance buffer circuits with high rms currents. Along with their very good ratio of capacitance to volume, these components do also have very good self-healing characteristics without loss of capacitance. Their very low self-inductance makes them suitable for use in high-current applications with medium frequencies. The capacitors of the E53 product family 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.

Using selected low-loss, self-healing polypropylene films and sophisticated manufacturing techniques such as high-vacuum drying and special coating patterns, the best of ELECTRONICON™s design expertise and highest care in manufacturing have been spent to prepare these capacitors for your most demanding applications, and toughest ambient conditions. Our long-life MKP UHDTM contain three delta-switched capacitor elements of short height and large diameter. The optimized combination of winding length, film size, and winding geometry substantially reduces inherent power losses and allows us to achieve highest surge and rms current ratings as well as an overvoltage strength and switching stability which before would have been known only of impregnated paper capacitors. An MKP UHD™ handles up to 250% of its rated current and current surges of 400 x IN. The permitted operating temperatures range from -40°C up to 70°C maximum temperature (average over 24 hours: 60°C).
