Principles: Aluminum electrolytic capacitors | ELNA CO., LTD.

Aluminum electrolytic capacitors are made by layering the electrolytic paper between the anode and cathode foils, and then coiling the result. The process of preparing an electrode facing the etched anode foil surface is extremely difficult. Therefore, the opposing electrode is created by filling the structure with an electrolyte. Due to this process, the electrolyte essentially functions

6 FAQs about [How to classify aluminum electrolytic capacitors]

What are aluminum electrolytic capacitors?

Aluminum electrolytic capacitors offer a large amount of capacitance per unit of volume for a given voltage rating. Aluminum electrolytic capacitors can be used in a wide variety of applications. Aluminum electrolytic capacitors have a large capacitance and high voltage rating, meaning high-energy storage capabilities.

What is the equivalent resistance of an aluminum electrolytic capacitor?

The capacitance of aluminum electrolytic capacitors changes with temperature and frequency of measurement, so the standard has been set to a frequency of 120Hz and temperature of 20oC. The equivalent circuit of an aluminum electrolytic capacitor is shown below, The equivalent series resistance is also known as "ESR".

What are the characteristics of aluminum capacitors?

The essential property of a capacitor is to store electrical charge. The amount of electrical charge (Q) in the capacitor (C) is proportional to the applied voltage (U). d = thickness of the dielectric (oxide layer in aluminum capacitors) (m). Characteristics of aluminum capacitors vary with temperature, time and applied voltage.

What are the tolerances for aluminum electrolytic capacitors?

While tolerances of ±5% and ±10% are routine for ceramic capacitors, ±20% and –10% +50% are the norms for aluminum electrolytic. This makes aluminum electrolytics the choice for high-capacitance applications like rectification filters and power hold up where more capacitance is a bonus.

How do you mount an aluminum electrolytic capacitor?

Mount the capacitors with the vents up to reduce the amount of electrolyte expelled if a vent operates. Aluminum electrolytic capacitors are normally polarized and require correct-polarity installation in the circuitry. To ensure correct mounting and identification of the polarity, put a clear + and/or – on the board layout marking.

What is a non polar aluminum electrolytic capacitor?

In non-polar aluminum electrolytic capacitors and motor-start aluminum electrolyte capacitors a second anode foil substitutes for the cathode foil to achieve a non-polar capacitor in a single case. These figures show typical constructions of the non-surface-mount aluminum electrolytic capacitors.
