FPX86X0205J

FPX RANGE Capacitor for Power Electronics Preliminary data sheet www.DataSheet4U.com Preliminary data FPX Applications Protection of thyristors . Protection of gate turn off thyristor (GTO) . Clamping (Secondary snubber) . www.DataSheet4U.com Technology Metallized polypropylene dielectric capacitor with controlled self healing . Reinforced metallisation developed for high impulse currents . Axial connections specially developed to reduce serial inductance and to provide rigid mechanical mounting . Presentation Cylindrical in plastic or epoxy case filled with thermosetting resin . Outputs : threaded inserts M6 or M8 . Electrical characteristics Climatic category : 40/085/56 (IEC 68) . Working Temperature : – 40 to + 85°C . Hot spot temperature 85°C (must be calculated : see page up) . Capacitance range : C = 0.5 µF to 6 µF . Tolerance : ± 5 % . Nominal dc voltage : Undc = 1000 to 3000 V . Peak voltage : Ucr = 1600 to 4000 V . Allowable overvoltage : Us = 2000 to 4600 V 10 s per day . RMS current : Irms max = 15 to 160 A . Impulse current : I2t max = up to 729 A2s . Spikes or peak currents in the capacitors may cause a deterioration of the bonding between the metallisation and connections . These bonds are capable of withstanding only a limited amount of energy for each spike . The table shows the maximum energy permitted in the form (I2.t), where I is in amps, and t is in seconds . The formula (I2.t) replaces dV/dt which is less easy to use as it is not an expression of...
