Radial Aluminum Electrolytic Capacitors – ESC, +105°C Mounting Positions (Safety Vent) In operation, electrolytic capacitors will always conduct a leakage current, which causes electrolysis. The oxygen produced by electrolysis will regenerate the dielectric layer but, at the same time, the hydrogen released may cause the internal pressure of the capacitor to increase. The overpressure vent, or safety vent, ensures that the gas can escape when the pressure reaches a certain value.
Radial Aluminum Electrolytic Capacitors – ESC, +105°C Application & Operation Guidelines Electrical Ratings: Capacitance (ESC) Simplified equivalent circuit diagram of an electrolytic capacitor The capacitive component of the equivalent series circuit, (equivalent series capacitance - ESC), is determined by applying an alternate voltage of ≤ 0.5 V at a frequency of 120 or 100 Hz and 20°C (IEC 384-1, 384-4). Capacitance Change vs.
Radial Aluminum Electrolytic Capacitors – ESC, +105°C Application & Operation Guidelines cont. Dissipation Factor tan δ (DF) Dissipation Factor tan δ is the ratio between the active and reactive power for a sinusoidal waveform voltage. It can be thought of as a measurement of the gap between an actual and ideal capacitor. reactive ideal δ actual active Tan δ is measured with the same set-up used for the series capacitance ESC.

Impedance as a function of frequency (sinusoidal waveform) for different temperature values can be represented as follows (typical values): Z (ohm) 10 µF 1,000 100 -40°C 10 20°C 85°C 1 0.1 0.1 1 10 100 1,000 10,000 F (K H z) Re is the most temperature-dependent component of an electrolytic capacitor equivalent circuit. Electrolyte resistivity will decrease if temperature rises.
Radial Aluminum Electrolytic Capacitors – ESC, +105°C Application & Operation Guidelines cont. Leakage Current (LC) cont. As the oxide layer is regenerated in use, the leakage current will gradually decrease to its normal level. The relationship between the leakage current and voltage applied at constant temperature can be shown schematically as follows: I Where: VF = Forming voltage If this level is exceeded, a large quantity of heat and gas will be generated and the capacitor could be damaged.

Radial Aluminum Electrolytic Capacitors – ESC, +105°C Construction Data The manufacturing process begins with the anode foil being electrochemically etched to increase the surface area and then “formed” to produce the aluminum oxide layer. Both the anode and cathode foils are then interleaved with absorbent paper and wound into a cylinder. During the winding process, aluminum tabs are attached to each foil to provide the electrical contact.
