Tantalum-polymer capacitors, also known as Ta-polymer capacitors, are an established type of electrolytic capacitor, named for the combination of solid tantalum metal used for their anodes and the polymer-based electrolyte material used as the cathode. The T55D227M010E0018 is a product from the Mitsubishi Specialty Components Series specifically designed for use in Module and Automotive applications.

Application Field

The T55D227M010E0018 is a robust and reliable electrolytic capacitor, suitable for a number of applications due to its comparatively low ESR and its wide operating range (-55 to +125 degrees Celsius). It is often used in automotive, industrial and military industries and applications where extreme vibration, shock, temperature and humidity are present. This includes automotive engine components, automotive braking systems, military weapons, industrial robotics and aerospace components.

Working Principles

Ta-polymer capacitors use two pieces of metal, usually one tantalum and one polymer, separated by an insulating material. This creates a capacitor of two concentric cylinders. When an electric current is applied, positive ions flow through the polymer and attract negatively charged electrons which build up in the center of the two cylinders. This builds the voltage potential of the capacitor.

Tantalum-polymer capacitors are known for their unusually low ESR. This means that the capacitor is able to hold a greater amount of energy and therefore discharge for a longer period of time. This makes them particularly useful for applications which require longer runtimes and less heat dissipation. The T55D227M010E0018 is no exception, with an ESR rated at 0.41 ohms at 25 degrees Celsius.

The T55D227M010E0018 is also very tolerant of environmental fluctuations. This is because the polymer component of the device is incredibly robust and can withstand temperature ranges of -55 to +125 degrees Celsius. As a result, the capacitor is suitable for use in extreme environments.

In terms of its physical properties, the T55D227M010E0018 is a compact component which is designed for vertical or horizontal mounting in a printed circuit board. It has a large capacitance range of 55uF to 10,000uF, making it suitable for a wide variety of dampening and smoothing applications. The device has a maximum operating voltage of 10V, making it suitable for a range of low and medium voltage applications.

Conclusion

The T55D227M010E0018 is an extremely reliable, robust and energy efficient capacitors, designed for use in harsh environments such as the automotive and military industries. Its ESR is unusually low for a tantalum-polymer capacitor, making it suitable for applications which require longer runtimes and less heat dissipation. Its wide temperature range, small physical size and large capacitance range make it suitable for a wide range of applications.
