fpx range capacitor for power electronics preliminary data sheet
fpx 2 applications protection of thyristors . protection of gate turn off thyristor (gto) . clamping (secondary snubber) . 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 : C 40 to + 85c . hot spot temperature 85c (must be calculated : see page up) . capacitance range : c = 0.5 f to 6 f . 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 : i 2 t max = up to 729 a 2 s . 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 (i 2 .t), where i is in amps, and t is in seconds . the formula (i 2 .t) replaces dv/dt which is less easy to use as it is not an expression of energy (i = c.dv/dt) . this type of capacitor has been designed to withstand high (i 2 .t) values . preliminary data
