Aluminium Electrolytic Capacitors

Aluminium electrolytic capacitors are composed of two metal plates separated from each other by an insulating dielectric layer. To provide a high capacitance and increase the voltage ratings, the capacitor is also filled with a liquid electrolyte, a mixture of water and other electrochemicals that bridge the gap between the two plates. The capacitor also has a polarized anode and cathode, so the correct polarity must be observed when connecting the capacitor in any circuit. The EEE-FK1K151AQ is an Aluminium Electrolytic Capacitor from the FK Series by Panasonic. This series is renowned for its low ESR (Equivalent Series Resistance) and long lifetime even at high temperatures. This makes them an excellent choice in many applications such as DC-DC converters, LED lighting, telecoms and automotive electronics.The EEE-FK1K151AQ has a capacitance rating of 1.5µF and a voltage rating of 16V. The maximum operating temperature for this capacitor is 85°C, and it has a maximum leakage current of 1.5mA. The main advantages of using an Aluminium Electrolytic Capacitor like the EEE-FK1K151AQ are its large capacitance, long lifetime and low cost. They also offer good mechanical strength and a large range of customised sizes and voltage ratings. In the case of the EEE-FK1K151AQ, the capacitor is made with an anodised aluminium case. The anodizing process adds an extra layer of protection to the capacitor which helps reduce corrosion and electrolyte leakage. This makes them an ideal choice for use in harsh environments such as industrial, medical or telecoms applications.The working principle of the EEE-FK1K151AQ is based on the principle of electrostatic energy storage. When an alternating voltage is applied to the capacitor plates, electrons are drawn towards one plate and away from the other plate, thus creating a potential difference across the plates. This potential difference is proportional to the capacitance and the applied voltage, and can be calculated using the following equation:C = Q/VWhere C is the capacitance (µF), Q is the charge stored on the plates (Coulombs) and V is the applied voltage (Volts).The self-healing process that takes place inside the capacitor, helps protect against excessive voltages. When an overvoltage is detected, a layer of metal oxide forms inside the capacitor which helps dissipate the overvoltage and eventually breaks down the charge carriers, repairing the capacitor. This helps the capacitor to survive short circuit or other overload conditions and last longer.To summarise, Aluminium Electrolytic Capacitors like the EEE-FK1K151AQ, provide high capacity and voltage ratings due to the electrolyte they are filled with. They also have low ESR and long lifetime, making them an ideal choice for many applications. They are also self-healing and offer good mechanical strength and a range of customised sizes and voltage ratings.
