Anode: aluminum foil 2. Dielectric: aluminum oxide 3. Papers spacers impregnated with electrolyte 4. Ionic conduction assumed by electrolyte 5. Cathode: aluminum foil The positive plate is an etched aluminum foil covered with alumina which is the dielectric of the capacitor. The negative plate is constituted by a second aluminum foil which serves as a current supply, and by electrolyte-impregnated papers layers. The metal used for anode is a ≥ 99,98 % grade aluminum. The dielectric has a thickness of 13 Å / V. The aluminum used for the cathode is a ≥ 98 % grade aluminum covered with a dielectric layer with a thickness of about 40 Å. 2.

ELECTRICAL CHARACTERISTICS CA = Capacitance of the anode CK = Capacitance of the cathode Rp = Parallel resistance due to the aluminum oxide f Ilms. RL = Series resistance of connections, plates and impregnated spacer. Ls = Inductance of winding and connections. 4.1. RATED CAPACITANCE CR The rated capacitance is defined at 100 Hz and at ambient temperature. 4.2. RATED VOLTAGE UR UR is the maximum DC voltage which may be applied in continuous operation. When applying a superimposed alternating voltage, the peak value of the resulting waveform should not exceed the rated voltage. A standard simplified diagram is. 4.3. PEAK VOLTAGE UP Up is the maximum repetitive voltage which can be applied within short periods. Defined in CECC 30 300 and IEC 60 384-4: Cs is the series capacitance of both anode and cathode capacitances. Electrolytic aluminum capacitors are naturally polarized because of the insulating f Ilm on the anode. Given the very thin aluminum oxide layer, a reversed voltage should not exceed 1.5 V when there is energy supply. 1000 cycles of 30 s charge followed by a no load period of 5 min. 30 s with upper category temperature. Up ≤ 1,15 UR (UR ≤ 315 V) Up ≤ 1,10 UR (UR > 315 V) Short duration reverse voltages can be absorbed by special construction, second anode replacing the former cathode.

Dissipated power versus case dimension For calculations of ripple currents, considering an internal temperature rise of 10°C Forced or not cooling air can lead to a significant decrease of these values. Consequently, r.m.s. ripple current can be increased as a function of air cooling speed: Ø mm (inches) 66 - 90 36 - 51 This parameter shall be applied to one capacitor alone. For capacitors in bank, ambient temperature must be strictly equal around all capacitors. 6.4.5. Quality guaranty...

When used horizontally, the following position in relation to the safety vent, is recommended: 8.1. CLEANING SOLVENTS Use aliphatic alcohols, such as denatured ethyl alcohol, isopropanol, or butylacetate, or else alkaline d Iluted solutions. Avoid incompatible solvents (halogenous for example). Mounting capacitors in series may be used for operating voltage exceeding UR. See FELSIC in bank. Prominent negative polarity indicator...
