What is 13008-020MESC/HR?

13008-020MESC/HR stands for Metallized Electrolytic Solid Capacitor, High Ripple. It is a type of tantalum capacitor. Tantalum capacitors are electrolytic capacitors that use a tantalum cathode that is chemically altered or ‘metallized’ for increased capacitance and stability. They are often referred to as “MECs” and are characterized by their high ripple current ratings, fast response, excellent frequency response and low ESR.

Applications of 13008-020MESC/HR

13008-020MESC/HR tantalum capacitors are commonly used in harsh environment applications such as those found in aerospace and military applications. They are frequently used in power, audio/video and DC/DC converters. They are also used for snubber circuits, decoupling circuits, high frequency circuits, pulse wave form generators and many other similar applications.

Working Principle of 13008-020MESC/HR

13008-020MESC/HR tantalum capacitors are composed of an anode (positive electrode) and a cathode (negative electrode) with an electrolytic dielectric material in between them. The anode is typically made of tantalum powder that is electrically charged, while the cathode is a metal oxide film. A recently developed process known as “metal-insulator-metal” (MIM) technology has created a more reliable capacitor with improved performance and far greater longevity.When a voltage is applied across the capacitor, the oxide layer on the cathode allows current to flow from the anode to the cathode. This is known as the charging cycle. As the capacitor reaches its full charge, the current becomes less and less until it stops completely. When the voltage is removed, the capacitor will then begin to discharge, slowly changing its voltage level until it reaches its original level.

Benefits and Disadvantages of 13008-020MESC/HR

The main benefit of 13008-020MESC/HR capacitors is their high ripple current ratings, fast response, excellent frequency response and low ESR. This makes them ideal for applications involving high-frequency AC signals and power supplies. The capacitors also offer excellent reliability, long life and low leakage. The main disadvantage of 13008-020MESC/HR capacitors is their limited temperature range. They can operate in temperatures from -55°C to +125°C. Another disadvantage is their high cost due to the precious metal plates required to form the capacitor. They are also more sensitive to vibration and shock than other types of electrolytic capacitors due to the very thin metal layers that make up the capacitor.

Conclusion

13008-020MESC/HR tantalum capacitors are a type of electrolytic capacitor that is characterized by their high ripple current ratings, fast response, and reliable construction. This makes them ideal for many harsh environment applications such as military and aerospace applications. They also offer excellent frequency response and low ESR. However, they are limited in temperature range and can be quite expensive due to their precious metal plates.
