Tantalum Capacitors

Tantalum capacitors are an electrochemical device consisting of a tantalum rod and two electrodes separated by a dielectric. Also known as tantalum electrolytic capacitors, they are made of tungsten oxide and tantalum oxide, which store electric charge. Tantalum capacitors are widely used in a variety of electronic applications, including audio and video equipment, because of their robustness and characteristics.The 1879065-5 tantalum capacitor is a type of surface mount electrolytic capacitor, where the anode and cathode connection is located at the surface of the component. Generally, the 1879065-5 tantalum capacitor is nickel plated, which increase the capacitor\'s resistance to corrosion and environmental humidity. In addition to 1879065-5 series, there are also SCH series and KD series.The 1879065-5 series tantalum capacitor is a chip package, and the external structure is composed of an anode, a negative electrode, a sleeve, a protective film and other components. The four major applications of 1879065-5 tantalum capacitors are: filtering, decoupling, bypassing and timing. As filtering, its main task is to eliminate the high frequency interference energy in the circuit, ensuring that it meets the signal integrity requirements; as decoupling, its task is to ensure the stability of the supply voltage, eliminate the power supply ripple, and prevent the influence of the interference signal from entering the circuit; as bypassing, its task is to form a bypass path in the circuit so that the high frequency signal passes through the capacitor and does not pass through the circuit; as timing, its task is to establish a network between different signals. In terms of working principles, the tantalum capacitors rely on capacitance and electrochemical potential to function. The main principle is to change the equivalent capacitance value of the current through the capacitor and the potential difference between its two terminals, so as to play an energy storing and transmitting role in the circuit. The equivalent capacitance depends on the dielectric constant of the dielectric embedded in the electrolyte of the capacitor, the size of the plates, the gap between the plates and the temperature of the capacitor.In terms of working parameters, the electrical characteristics of tantalum capacitors mainly include rated temperature, maximum voltage, rated capacitance, equivalent series resistance, and insulation resistance. In voltage selection, manufacturers generally mark the maximum voltage that the capacitor can withstand in the capacitor nameplate. In the process of utilization, attention should be paid to controlling the working voltage of the capacitor to 50% of the upper limit voltage. As for the rated capacitance, it is dependent on the parameters of the capacitor and should be controlled within the rated range. The temperature at which the capacitor is able to work is called the rated temperature which is also listed on the nameplate. For equivalent series resistance and insulation resistance, attention should be paid to not directly contact the power supply voltage with the capacitor to prevent device damage. In conclusion, the catalog 1879065-5 tantalum capacitor is composed of a tantalum rod, a protective film, a sleeve and two electrodes separated by a dielectric. It mainly applies to filtering, decoupling, bypassing and timing, and the parameters mainly include rated temperature, maximum voltage, rated capacitance, equivalent series resistance, and insulation resistance. With its robustness and characteristics, tantalum capacitors are widely used in a wide range of electronic applications.
