Tantalum Capacitors

Tantalum capacitors are a type of electrolytic capacitor, which use an oxide layer of tantalum as the dielectric material in its construction. The construction of these capacitors can be divided into two varieties, namely solid-tantalum and wet-tantalum variants. Each type of capacitor has its own particular set of advantages and applications. In this article, we’ll take a look at the application field and working principle of TAJD685K050H, a particularly popular solid-tantalum capacitor.

Application Field

Solid-tantalum capacitors are used in a variety of different electronics applications. They are highly prized for their small size, low cost, high reliability, and low impedance. As such, they are often used in high-volume devices such as computers, electronic medical equipment, cell phones, and other handheld devices. The TAJD685K050H is a particularly popular part due to its low ESR rating and high capacitance, making it suitable for many different applications.

Working Principle

The working principle of a tantalum capacitor is based on the storage of electric charge in an anodic oxide layer formed on the surface of the tantalum cathode. The capacitance of the device is determined by the area of the oxide layer relative to the total surface area. The device is charged through the application of electric or AC currents to the capacitor, and the charges are stored within the oxide layer. The electric current is then allowed to flow through the charge stored within the dielectric, creating a current which is used to power the device.

The TAJD685K050H is an axial leaded capacitor, meaning that it features leads that extend outward from each end of the device. The capacitor’s leads are terminated with crimp connectors, which allows for secure connection and easy installation. The unit features an ESR (Equivalent Series Resistance) rating of 8.2 mΩ, making it highly reliable and efficient. The capacitance of the device is rated at 50 µF and the maximum operating temperature is 85ºC.

Advantages

The number one advantage of using TAJD685K050H is its ability to deliver high reliability and long operating life. The oxide layer acts as a barrier and prevents current leakage, thereby significantly reducing the risk of device failure due to overcharge or overdischarge. The capacitor also has a high level of reliability when exposed to high temperatures, making it ideal for use in applications that require robust and reliable performance.

Additionally, the capacitor is extremely low in size and weight, enabling it to fit into small spaces and reduce weight in applications requiring high capacitance. This makes it perfect for use in portable and handheld devices where space and power are at a premium.

Conclusion

The TAJD685K050H capacitor is a solid-tantalum variant that offers a high degree of reliability and performance. It is suitable for a wide range of applications, including computers, medical equipment, cell phones, and other handheld devices. The device features a low ESR rating, low impedance, high capacitance, and maximum operating temperature of 85°C. It is highly reliable and cost-effective and is perfect for use in applications where long life, high reliability and low size are important.
