An aluminum electrolytic capacitor, also named electrolytic capacitor (E-cap), is a capacitor whose anode (+) consists of pure aluminum foil with an etched surface, covered with a evenly very thin barrier layer of insulating aluminum oxide.It operates as a dielectric. The electrolyte, covering the rough surface of the oxide layer, operates as the second electrode, the cathode (-). E-caps have the largest capacitance values per unit volume compared to the two other main conventional capacitor families, ceramic and plastic film capacitors, but much smaller capacitance than similar sized supercapacitors.

3, Leakage: Although electrolytic capacitors have much higher levels of capacitance for a given volume than most other capacitor technologies, they can also have a higher level of leakage. This is not a problem for most applications, such as when they are used in power supplies. However under some circumstances they are not suitable. For example they should not be used around the input circuitry of an operational amplifier. Here even a small amount of leakage can cause problems because of the high input impedance levels of the op-amp. It is also worth noting that the levels of leakage are considerably higher in the reverse direction.

4, Ripple current: When using electrolytic capacitors in high current applications such as the reservoir capacitor of a power supply, it is necessary to consider the ripple current it is likely to experience. Capacitors have a maximum ripple current they can supply. Above this they can become too hot which will reduce their life. In extreme cases it can cause the capacitor to fail. Accordingly it is necessary to calculate the expected ripple current and check that it is within the manufacturers maximum ratings.

5, Tolerance: Electrolytic capacitors have a very wide tolerance. Often capacitors may be quoted as -20% and +80%. This is not normally a problem in applications such as decoupling or power supply smoothing, etc. However they should not be used in circuits where the exact value is of importance.

1, ESR Equivalent series resistance: Electrolytic capacitors are often used in circuits where current levels are relatively high. Also under some circumstances and current sourced from them needs to have a low source impedance, for example when the capacitor is being used in a power supply circuit as a reservoir capacitor. Under these conditions it is necessary to consult the manufacturers datasheets to discover whether the electrolytic capacitor chosen will meet the requirements for the circuit. If the ESR is high, then it will not be able to deliver the required amount of current in the circuit, without a voltage drop resulting from the ESR which will be seen as a source resistance.

2, Frequency response: One of the problems with electrolytic capacitors is that they have a limited frequency response. It is found that their ESR rises with frequency and this generally limits their use to frequencies below about 100 kHz. This is particularly true for large capacitors, and even the smaller electrolytic capacitors should not be relied upon at high frequencies. To gain exact details it is necessary to consult the manufacturers data for a given part.

Kingtronics Aluminum electrolytic capacitors are used in virtually every segment of the electronics industry, such as VTRs, videos, cameras, car radios and micro cassette tape recorders, etc.The longer lead is positive electrode and the shorter one is negative electrode.

General purpose and can be used in Industrial. Aluminum electrolytic capacitors are widely used to provide temporary voltage hold-up (they act as short-term energy sources) during transition periods (high load, line droops, and transient events).

Aluminum Electrolytic Capacitor, simply called Eelectrolytic Capacitor (e-cap), is a type of capacitor that uses electrolyte to achieve larger capacitance than other capacitor types. It consists of cathode aluminum foil, electrolytic paper, electrolyte, and aluminum oxide film, which acts as the dielectric, formed on the anode foil surface.

Due to its large capacitance, Aluminum Electrolytic Capacitor is suitable for passing or bypassing low frequency signals and storing large amounts of energy. It widely be used in power supplies and for decoupling unwanted AC components from DC power connections.
