Tantalum Capacitors: M39003/01-7231/TR Application Field and Working PrincipleTantalum capacitors are type of electrolytic capacitors that are made up of tantalum metal being a negative electrode (anode) and a solid manganese dioxide being a positive electrode (cathode). World War II bomber planes have used them, since they could offer a smaller form factor than other more bulky capacitors while providing a larger capacitance. As technology advances and their cost decreases, they have become commonly used in various electrical applications. Unlike conventional capacitors, tantalum capacitors can store very high levels of charge when compared with other passive electronic components. As such, the M39003/01-7231/TR capacitors from the same family of components are versatile for various applications and they are primarily used in filter networks, energy storage and signal timing.Principle of Operation: This type of capacitor can be seen essentially as a battery cell, where a chemical reaction takes place that generates a capacitance effect. From a technical standpoint, they operate similarly to aluminum electrolytic capacitors, however, their construction is based on tantalum instead of aluminum. This capacitor utilizes a dielectric of tantalum oxide which builds an electric charge between the electrodes and provides a desired capacitance. To develop the electrical charge, a voltage is applied across the terminals which subtracts electrons from the oxide resulting in a negative charge on the tantalum anode. A positive charge is created on the other side of the dielectric oxide. During the charge up process, the electrons of the anode collect on the oxide layer and are therefore distributed within the capacitor. This process continues until the dielectric oxide reaches its full capacitance. The capacitance remains stored until power to the capacitor is removed, causing electrons to lose their foil-like layers and start coming back to the anode before the capacitor starts discharging.Application Fields: M39003/01-7231/TR capacitors are primarily used in filter networks, energy storage and signal timing. As such, they are usually employed in industrial and automotive applications as part of a filtering system. For instance, they are used in the electrical systems of cars, trucks, solar cells, wind turbines, and telecom equipment. Also, M39003/01-7231/TR capacitors are used in power supplies and audio equipment as part of the signal coupling network. Moreover, they are found in CPUs, memory chips, and various other electronic circuits.Moreover, since they are low-profile and have high capacitance, they offer excellent performance for use in small form factor systems such as smartphones or laptops. These capacitors can also be used in audio equipment as part of the signal coupling network.Conclusion: In conclusion, there is no doubt that the M39003/01-7231/TR capacitors from the tantalum capacitor family are versatile and provide good performance for various applications. From filter networks, energy storage, and signal timing to industrial and automotive purposes, these components have proven to be reliable and cost-effective. Furthermore, due to their small size and efficient power capability, they are becoming increasingly popular in the electronics industry.
