13008-071MESB

Tantalum capacitors are electrochemical capacitors in which tantalum oxide is the anode and the cathode is formed by depositing low resistance and solid electrolytic oxide on an electrolytic tantalum powder core. Generally, it is a type of capacitor which uses tantalum as an anode, and a vacuum-deposited film as a dielectric. Depending on the type of dielectric used, it can be divided into two types, the tantalum electrolytic capacitor and the tantalum solid capacitor. 13008-071MESB is a type of tantalum capacitor.

Application Field

Tantalum capacitors are widely used in various electronic circuits owing to its excellent features such as small volume, large capacitance, high stability, high reliability, and low leakage current. 13008-071MESB capacitors are commonly used in consumer electronics, such as smartphones, tablets, CD/DVD players, televisions, and car navigation. It is also used for industrial and automotive applications, such as power converters, microcontrollers, signal processors, backlight inverters, motor control, and power management.

Working Principle

13008-071MESB capacitors work on the principle of electrical double layer capacitors, which consists of two layers of electrostatic accumulation. The anode of the capacitor is made of metal, such as tantalum or niobium, which is porous and allows for the electrolyte to penetrate the anode\'s surface. The electrolyte used in 13008-071MESB capacitors is typically an organic solvent, such as propylene carbonate, mixed with an electrolyte salt such as LiPF6. The resulting liquid electrolyte forms two electrically conductive layers: the anode, where the positive ions are attracted to the metal, and the cathode, where the negative ions are attracted to the dielectric film. As the two layers become sandwiched between the anode and cathode, a charge separation is created, allowing the capacitor to store electrical energy. When a voltage is applied across the capacitor, charge is stored on the interface between the two layers and the resulting electrical field increases the capacitance of the capacitor.

Conclusion

13008-071MESB capacitors are a type of tantalum capacitor and are commonly used in consumer electronics, industrial and automotive applications. The working principle of these capacitors is the electrical double layer, where two layers of electrostatic accumulation are formed at the anode and cathode of the capacitor which allows for charge separation and storage of electrical energy. As such, 13008-071MESB capacitors are able to provide reliable operation and an increased capacitance when exposed to a voltage.
