APPLICATIONS

Protection of thyristors. Protection of gate turn-off thyristor (G.T.O.). Clamping (Secondary snubber). TECHNOLOGY Metallized polypropylene dielectric capacitor with controlled self-healing. Reinforced metallization developed for high impulse currents. Axial connections specially developed to reduce series inductance and to provide rigid mechanical mounting. PACKAGING MATERIAL Cylindrical in plastic case filled with thermosetting resin. Outputs: threaded inserts either M6 or M8. HOT SPOT TEMPERATURE CALCULATION See Hot Spot Temperature page 3. θhot spot = θterminals + (Pd + Pt) x Rth with Pd (Dielectric losses) = Q x tgδ0 ⇒ [ 1⁄2 x Cn x (Vpeak to peak)2 x f ] x (2 x 10 -4) Pt (Thermal losses) = Rs x (Irms)2 where Cn in Farads Vi n V o l t s Irms in Amperes Rs in Ohms f in Hertz θ in °C Rth in °C/W Due to the design of the capacitor and its technology, the thermal impedance between the terminations and the core of the capacitor is low, it is necessary to take care that the capaci- tor is never overheated by use of incorrect sized connections. In the case where the series diodes are screwed to the capaci- tor, cooling of the diodes must be taken in account. Do not use the capacitor as a heat sink. Due to the complexity of the diode/capacitor thermal exchanges, we recommend that thermal measurements shall be made on the different components. We would be pleased to advise you on specific problems. WORKING TEMPERATURE (according to the power to be dissipated) -40°C to +85°C Not RoHS Compliant Please select correct termination style.

JUNE 2015 ■ 83 Medium Power Film Capacitors FPX (FPY RoHS Compliant) Capacitance range Cn 0.5μF to 6μF Tolerance on Cn ±5% Rated DC voltage Vndc 1000 to 3000 V Peak voltage Vpeak 1600 to 4000 V Allowable overvoltage Vs (for 10 s/day) 2000 to 4600 V Stray inductance 5 to 20 nH RMS current I rms max. = up to 160 A The currents shown in the tables are maximum. It is necessary to respect the thermal limits of the dielectric 85°C see “Hot spot temperature calculation” Insulation resistance R i x C ≥ 30,000 s Impulse current I 2.t maxi. = up to 729 A2.s Spikes or peak currents in the capacitors may cause a deterioration of the bonding between the metallization and the 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 Ampere, and t is in seconds. Note: The formula (I2.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 (I2.t) values.
