Among all the raw materials for aluminum electrolytic capacitors, there is no doubt that the anode foil is one of the most important raw materials influencing the performance of capacitors. The voltage, capacitance, thickness and impurity content of the anode foil have a direct effect on the performance of capacitor.
Against such a background, this article evaluates the anode foil of a new supplier to be used in a 400 V medium and in a high voltage aluminum electrolytic capacitor with the purpose of minimizing the product costs while achieving the same performance.
The basic material of the anode for aluminum electrolytic capacitors is a foil with a thickness of ~ 20–100 μm made of aluminum with a high purity of at least 99.99%. This is etched (roughened) in an electrochemical process to increase the effective electrode surface.
Aluminum electrolytic capacitors with non-solid electrolyte are relatively insensitive to high and short-term transient voltages higher than the surge voltage, if the frequency and the energy content of the transients is low. This ability depends on the rated voltage and component size.
The voltage, capacitance, thickness and impurity content of the anode foil have a direct effect on the performance of capacitor. The cost of anodes also contributes to the total cost of capacitors by a high percentage.
Aluminum electrolytic capacitors with non-solid electrolytes have an exceptional position among electronic components because they work with an electrolyte as liquid ingredient. The liquid electrolyte determines the time-dependent behavior of electrolytic capacitors. They age over time as the electrolyte evaporates.
