Tantalum capacitors, also commonly referred to as solid electrolytic capacitors, are devices that provide electrical energy storage. They are used in many different applications and the T95R0225M010HZSS (T95R) is one example of a tantalum capacitor designed for a specific application. This article will go over the application field and working principle of the T95R.

Application Field

The T95R is a low-temperature, high-performance chip capacitor. It is designed to meet the needs of high-reliability and radiation-hardened electronics applications for space and avionics systems. The T95R is carefully designed to be robust against harsh environmental conditions including temperature extremes, shock, vibration, and exposure to a wide range of radiation spectrums. It is designed to operate within the temperature range of -65 to +150Centigrade, and also rated for voltages between 2.5 and 6.3 volts.

The T95R also provides high capacitance density at a very low profile size. This capacitor is designed to occupy very little board space while still providing a high capacitance value, making it ideal for space-constrained applications. The T95R is very reliable and shrink-wrapped in a lightweight resin option for a superior drop performance. It also uses a flexible termination to enhance the reliability of the device.

Working Principle

The T95R is a solid-state capacitor that uses an electrolyte solution sandwiched between two electroplated layers of tantalum powder. This type of capacitor offers very high levels of capacitance and conductivity. The working principle of a tantalum capacitor is based on an electrochemical effect that occurs between the electroplated layers of tantalum powder and the electrolyte solution. When a voltage is applied to the plates, the electrolyte allows electrons to flow freely through the membrane which in turn causes a charge to be stored on each of the plates.

The electrolyte solution also serves to prevent the occurrence of a short circuit due to a build up of electrostatic charge. This is done through the use of an ion exchange reaction which allows the positive and negative ions to flow freely through the membrane. This type of capacitor is very effective in providing a high capacitance value while still maintaining a low profile size, making it ideal for applications in which space is a factor.

Conclusion

The T95R0225M010HZSS (T95R) is a carefully designed tantalum capacitor that provides high capacitance density in a very low profile size. It is ideal for high-reliability and radiation-hardened electronics applications in space and avionics systems due to its robustness against harsh environmental conditions and its ability to provide high levels of capacitance and conductivity at a low profile size. The working principle of this type of capacitor is based on an electrochemical effect that occurs between the electroplated layers of tantalum powder and the electrolyte solution.
