Tantalum capacitors are electronic components that use tantalum as a main electrical conductor within a capacitor. These types of capacitors are available in radial, surface mount and axial lead forms. Compared to other types of capacitors, tantalum capacitors have very high electrical stability and low leakage currents. This makes them ideal for various high-frequency applications where high accuracy and low power dissipation are required. The 13008-051MESC/HR application field and working principle, which are discussed in this article, are specifically related to tantalum capacitors.

Description

The 13008-051MESC/HR is a metalized tantalum capacitor, which is built on a niobium-oxide based anode with zinc/tantalum overlayer. The capacitor is available in a radial leaded, single-ending and axial leaded, double-ending form factor. It is intended for DC-DC converters, DC-AC inverters and motor drive circuits operating at frequencies up to 1.25 MHz.This type of capacitor is suitable for applications where improved temperature cycling performance and wide voltage range operation is needed.

Application Field

The 13008-051MESC/HR is suitable for use in the following application fields:

• Power supplies
• AC and DC-DC opto-isolator circuits
• DC-DC converters
• DC-AC inverters
• Motor drive circuits
• High frequency switching circuits

Working Principle

Tantalum capacitors work on a similar principle to most other capacitors, where electrons are stored in a dielectric material between two conductors. The electrons remain stable until they are either too densely packed, resulting in an electrical current, or they are stimulated by an outside source. The electrons stored in a tantalum capacitor can be released rapidly, which is why they are used in high-frequency applications.

The 13008-051MESC/HR capacitor operates differently from most other capacitors due to the characteristics of the anode which consists of a niobium-oxide based material with a zinc/tantalum overlayer. The structure of the anode allows the capacitor to operate at temperatures up to 125?C with minimal capacitance degradation. Additionally, the capacitor\'s temperature and voltage characteristics are 30% lower than most other capacitors, making it suitable for high-frequency applications.

The capacitor also has high self-discharge characteristics that make it less susceptible to damage by excessive charging and discharging. Additionally, it has extremely low internal resistance which ensures high efficiency in power supply applications.

Conclusion

The 13008-051MESC/HR is a high-performance tantalum capacitor specifically designed for use in high-frequency applications. It is available in a radial and axial lead form and can operate at temperatures up to 125?C. Due to its unique anode construction, the capacitor is able to provide high levels of stability compared to most other types of capacitors. Additionally, it has high self-discharge characteristics and extremely low internal resistance, making it the ideal choice for a variety of power supply applications.
