Tantalum Capacitors

Tantalum capacitors are small electronic components used in a variety of electronic circuits, and they have a variety of applications in the electronics industry. They are composed of two metal plates insulated by a thin layer of insulation and often have an electrolyte solution within them. The two metal plates are usually made of either tantalum or another metal, such as niobium, which, when used together, form a capacitor. The combination of the two materials, the two metal plates and the insulation, create a specific capacitance value that varies depending on the size and type of the capacitors.

The main advantage of tantalum capacitors is that they are very small and offer a high capacitance value in comparison to other capacitors of the same size. For this reason, they are often chosen for a number of applications over their larger counterparts, such as for use in low power circuits or DC-DC converters. The downside of these types of capacitors is that they have a lower tolerance of high temperature and voltage than other types of capacitors, making them unsuitable for high temperature or high voltage applications. Additionally, tantalum capacitors are prone to failure due to corrosion if they are exposed to moisture.

There are two different types of tantalum capacitors: solid and electrolytic. Solid tantalum capacitors are the most common type, and they are often used in low voltage applications where the accuracy and lifespan of a capacitor do not need to be extremely high. These types of capacitors are typically packaged in plastic or ceramic cases, and the capacitance value is determined by the size of the plate and the dielectric material that is used in the construction of the capacitor. Electrolytic tantalum capacitors, on the other hand, offer much higher capacitance values than solid tantalum capacitors, and they are often used in higher voltage applications. The capacitance value is determined by the size of the plate and an electrolyte solution that is placed between the plates.

The 7-1879055-7 application field and working principle of the tantalum capacitor typically fall under the umbrella of DC power supply circuits, DC-DC converters or other low voltage circuits. It is important to note that the capacitance value will vary depending on the voltage applied across it. The working principle of the 7-1879055-7 is relatively straightforward - when current is applied to the capacitor, it stores electrical energy between the two plates, which is then discharged when the voltage drops. In the event of failure, the 7-1879055-7 has a safety valve to protect against potential damage to the surrounding components. As with other capacitors, the 7-1879055-7 needs to be properly discharged before being removed for replacement.

Tantalum capacitors are a popular choice for many electronic applications due to their high capacitance value, small size, and cost-effectiveness. However, it is important to remember that their higher temperature and voltage tolerance make them unsuitable for certain applications, and they may need to be replaced with a more appropriate capacitor for higher temperature and voltage applications. Additionally, it is essential to carefully consider the capacitance values required for a given application, as the size, shape and construction of the capacitor will affect the capacitance value.
