TDK-EPC is offering new EPCOS power capacitors with higher rated voltages from 550 VRMS a.c. up to 1000 VRMS a.c. The MKP AC HP B25360* series covers a capacitance range from 10 to 150 μF.
The components’ high dielectric strength is made possible by a castor oil filling. Another advantage of their new design lies in the improved heat dissipation from the capacitor’s interior to the aluminium can. In addition, hot spots are reduced and enhanced insulation properties are achieved, thus extending the operating life of the components to 100 000 hours (to IEC 61071). The capacitance changes by no more than 3%.
Thanks to their high rated voltage, long operating life and high current handling capability, these capacitors are particularly well suited for renewable energy generation applications. They are designed for a temperature range from -40°C to +70°C. M10 screw terminals assure a reliable electrical connection. The terminals can be modified according to the specific requirements of the customer or application. The cans have diameters of 75 or 85 mm and their heights are between 115 and 270 mm.
Thanks to the over-pressure disconnector, these capacitors represent no hazard in the event of overload. Like all EPCOS film capacitors, the new series is also self-healing: spark-overs due to excessive voltages do not short circuit or destroy the capacitor.
