Tantalum Capacitors

Tantalum capacitors, also known as Ta-capacitors or tantalum electrolytic capacitors, are a type of electrolytic capacitor. They consist of two metal foils. One is an anode, usually made of tantalum, and the other is a cathode, constructed from tantalum oxide, which is deposited on the anode. The foils are rolled up, and then inserted into a metal jacket. Tantalum capacitors are available in a number of different shapes and sizes, with various capacitance values.

T95S685M004HZSL capacitors are a type of tantalum capacitor specifically designed for use in high-temperature environments, such as in automotive and avionics applications. They are designed to operate between -55°C to +125°C. Their maximum ripple current is 125mA and surge current of 350mA.

Application Field

T95S685M004HZSL capacitors are widely used in applications where pulse loadings, temperature cycling, and high shock and vibration levels are present. They are commonly used in telecommunications, industrial controls, automotive, and power supplies. They are also extensively used in military and aerospace applications due to their long-term reliability and stability.

Working Principle

Tantalum capacitors operate on the same principle as other electrolytic capacitors. The anode of the capacitor is connected to a positive terminal and the cathode is connected to a negative terminal. When a potential difference is created between the terminals, an electric field is established within the capacitor, causing electrons to be repelled from the anode and attracted towards the cathode. This creates an electric current that enables the capacitor to store energy.

The electrolytic nature of the capacitor also allows for the dielectric material to be formed within the capacitor, which greatly increases its capacitance and voltage rating. This material is formed from a reaction between the anode metal and the electrolyte. This reaction creates an inorganic, solid film of dielectric material that increases the capacitance and voltage rating of the capacitor.

Conclusion

T95S685M004HZSL capacitors offer a high level of performance in high-temperature environments, as well as excellent reliability and stability. They are widely used in telecommunications, industrial controls, automotive, and power supplies, as well as in military and aerospace applications. Their working principle is the same as other electrolytic capacitors, with the electrolytic nature of the capacitor allowing for the dielectric material to be formed, providing increased capacitance and voltage ratings.
