Angular DC capacitors
E59-DC
Square DC capacitors with large capacitances and high rated currents, in robust and vibration-resistant housings, tailored to your individual requirements.
The capacitors in the E59 series combine high capacitance, low self-inductance and high surge current resistance (up to 1000kA) as well as the possibility of high RMS currents of up to 1400A thanks to the special films, coatings and winding geometries used in them as well as their sophisticated internal construction. Instead of flat winding packages, we use cylindrical windings to build up the capacitance without the high mechanical stress and instability at the kinks that are typical of flat windings.
The self-inductance is further reduced by special flat connections. The capacitors have a very favorable capacitance-to-volume ratio and are also exceptionally overvoltage-resistant. This makes them particularly suitable for suction and intermediate circuits of inverters, filter circuits, etc.
Large capacities made to measure.
The capacitors are housed in either steel or aluminum housings and filled with cured resin, making them completely dry and leak-proof. Their shape and size can be adapted to the respective requirements of our customers. Even at high operating temperatures and after increased self-healing processes, the capacity remains largely constant.
An integrated pressure switch responds at a pressure increase of 0.5 bar and closes (optionally: opens) a contact; this enables reliable monitoring of the internal pressure and safe shutdown in the event of overload or failure at the end of the service life. Available from 250mF 500V DC to 100µF 25,000V DC, AC voltages up to 17,000V AC; exact values depend on customer specifications.
Electronicon offers film capacitors "Made in Germany". From the coating of the film to the winding and manufacturing of the capacitors, the entire process takes place at the plant in Gera. Film capacitors offer various advantages in power electronics and are environmentally friendly in production.
Since the early forties, when SIEMENS&HALSKE AG moved parts of their production from Berlin to East Thuringia in the heart of Germany, capacitors have been manufactured by ELECTRONICON Kondensatoren GmbH (formerly RFT Kondensatorenwerk) in Gera. Highest quality and reliability of all products have been the basis of their company philosophy from the very beginning. Especially since its spin-off from the former East German electrical company RFT/VEB ELEKTRONIK Gera in autumn 1992, ELECTRONICON has succeeded in becoming one of the leading capacitor manufacturers in Europe with worldwide supply relations by continuously expanding and improving its product range. More than 500 qualified engineers and skilled workers produce capacitors and accessories for lighting and drive technology, power electrics and electronics, and power factor correction. Extensive investments in modern and environmentally friendly technologies guarantee the highest standards in manufacturing and quality assurance. The products of ELECTRONICON Kondensatoren GmbH are approved according to the latest standards by international testing institutions. ELECTRONICON's quality assurance system is monitored by TÜV according to ISO 9001. Since 1942 ELECTRONICON has been able to metallize its dielectric materials itself using the latest technologies. This ensures uninterrupted quality assurance from the raw foil to the finished capacitor.
