Aluminum electrolytic capacitors are electronic components that hold a voltage and store electrical energy. The possession of a high dielectric strength makes them suitable for applications in electric and electronic appliances, and are particularly suited to situations where the supply of energy must be maintained during drastic changes in voltage levels and/or frequency. Amongst their many uses, they are particularly advantageous in applications where the control of inrush current or the smoothing of pulsating DC circuits is necessary.When it comes to the 139R323M7R5AB2A specifically, its application field is in medium-voltage applications up to 630 V, such as power supplies, UPS, inverters, and IGBT inverter drive units. This capacity ranges between 1000-10000 μF and the maximum rated temperature is 125°C. Its capacitance and temperature coefficient are highly stable, giving it the capacity to store energy efficiently.The non-solid electrolyte of this capacitor ensures that few losses are encountered during use. Its electrolyte contains solid-state elements, which further protect it from any inrush-current damage. This capacitor also features a wide voltage range, high dielectric strength and its long working life only enhances its value in the appliance industry.In terms of its construction and working principle, it is physically smaller than other, similarly rated capacitors, due to its solid electrolyte design, allowing for consistent performance in smaller, more compact applications. Its working principle is that two electrodes of disparate metals are placed in a container, separated by a dielectric. When voltage is applied to the capacitor, one of the electrodes becomes an anode, while the other becomes a cathode. The formation of a dielectric field takes place between these electrodes, allowing for the storage of electric energy.It uses a solid-state screw terminal, which allows for easy fitting through 4.2 mm grade mounting holes. The pin fastening makes it incredibly secure and its double-pin design facilitates quicker installation. Its cylindrical shape and solid electrolyte also provide electrical insulation and reduce losses associated with other, similarly rated capacitors. This makes it the perfect choice for complex operating conditions, voltage distortions and high operating temperatures.The capacitance of 139R323M7R5AB2A is highly stable and it is able to withstand a large temperature range. Its heat dissipation is also far superior to predecessors, as it is able to dissipate more energy than other capacitors when used under high temperatures. Its life expectancy is top-notch, with the expected life of over 2000 hours of continuous use.In conclusion, the 139R323M7R5AB2A belongs to the Aluminum Electrolytic Capacitor family and offers a wide range of advantages for medium-voltage applications up to 630 V. Its construction and working principle give it high stability and reliability in operations, while its compact size allows for ease in fitting into complex operating conditions. Its excellent heat dissipation capabilities also set it apart from other capacitors that are rated similarly.
