Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in a number of applications because of their useful properties. This type of capacitors (called electrolytic because they are composed of two electrodes separated by an electrolyte, often composed of aqueous acid) offers a larger capacity of energy storage than usual capacitors with small size and low weight.

The procedure to obtain an aluminum electrolytic capacitor consists of stacking a thin aluminium foil that serves as a cathode, which may be coated with an oxide layer for improving the current dissipation, a separator, which is generally nylon 6,6, and a sheet of an absorbent material soaked in an ionic conducting solution. The anode wire is connected to the aluminum foil. This assembly is then rolled into a tube, sealed by a cover of epoxy resin, featuring an external terminal connected to the foil and internally to the anode wire.

The EEE-TG1V681M aluminum electrolytic capacitor is a radial, snap-in type, a format suitable for multi-layer PCB’s, where the snap allows it to be mounted with no soldering. The EEE-TG1V681M is a long life capacitor, of 8x12mm dimension and 5.5mm height, with a temperature range of -40 to +105 ºC. This electrolytic features a rated voltage of 16V DC and a capacitance of 680uF.

The working principle of an electrolytic capacitor is based in electrochemistry. When an external electric power supply applies a voltage to the capacitor, an electric current lightens the anode and provides the required power to the electrolyte. The ions in the electrolyte then manage to plate the anodes, forming dielectric layers that serve as insulation for the electrostatic fields created by the electric charges of the cathode and the anode. This electric field induces a polarization of the molecules, moving the electrons and creating a structure that enables the storage of energy.

The polarized ions that form the dielectric enable a number of features, such as high capacitance (related to the dimensions of the capacitor), long life time, due to the solid oxide layer that provides electro-chemical stability, and low leakage current.

In terms of application fields, the EEE-TG1V681M capacitor is suitable for a wide range of low voltage applications, such as domestic appliances, lighting, electric motors, UPS systems, sound systems, medical instruments, computer elements, telecommunication systems and automotive or transportation systems.

Notwithstandig their useful properties, electrolytic capacitors need to be correctly mounted and wired to take advantage of their useful features. In order to prevent capapcitor overload, for instance, it is important to restrict inrush current to avoid capacitor overload and keep the capacitor withing its rated temperature range. Electrolytic capacitors are sensitive to hot spots, too, so the surrounding temperature should not exceed the capacitor’s temperature range during operation.

In conclusion, aluminum electrolytic capacitors are widely used in a number of applications due to their useful features. The EEE-TG1V681M is a 16V DC radial type capacitor, with a capacitance of 680µF, suitable for a wide range of applications. The working principle of this type of capacitors is based on electrochemistry, taking advantage of polarized dielectric layers to enable an efficient energy storage. Careful mounting procedures are needed to take advantage of its features and avoid overload.
