Tantalum Capacitors

Tantalum capacitors are widely used in many electronic devices due to their advantages over other types of capacitors. These advantages include small size, high temperature stability, low power consumption, and high dielectric strength. Tantalum capacitors can also operate over a wide frequency range and provide excellent pulsed capacitance characteristics. The T95S685K004EZSL is a surface-mount multi-anode tantalum capacitor designed to meet the demands of various application fields.

Application Field

The T95S685K004EZSL is primarily used in automotive, telecommunications, audio, and industrial control applications. It is also designed for power supply designs requiring a high voltage rating, low ESR, and low ESL. It can also operate reliably in a variety of ambient temperatures, operating conditions, and prolonged life span. In addition to its small size, this capacitor has a standard lead spacing and is easily mountable in surface-mount technology.

The capacitor is suitable for pulsed power applications such as USB power supplies and current limiters, as well as mobile batteries such as those in portable devices. This capacitor is also useful in other industrial applications requiring a surface-mount capacitor, such as mild switching mode power supplies, and in power circuits in drones and robotics.

Working Principle

The T95S685K004EZSL is a wet-stacked multi-layer capacitor with a tantalum core which has been chemically treated. The high permittivity of the core and the electrolyte enables a layer of oxide to form between the anode and the cathode, creating a highly stable dielectric that holds the electrical charge. Tantalum capacitors have two basic characteristics. The first is the current rating, which is the maximum amount of current that the capacitor can handle. The second is the voltage rating, which is the maximum voltage that the capacitor can handle.

The capacitor works on the principle of capacitor charge and discharge. When current is applied to the capacitor, the electrons stored in the oxide layer between the anode and the cathode are released, creating an electric field and causing the capacitor to charge. When the current is removed, the charge stored in the capacitor is gradually discharged through the anode and the cathode. This process is known as the capacitance decay.

Conclusion

Tantalum capacitors offer many advantages such as small size, high temperature stability, low power consumption, and a high dielectric strength. The T95S685K004EZSL is a surface-mount multi-anode tantalum capacitor designed to provide these benefits to various application fields, such as automotive, telecommunications, audio, and industrial control. This capacitor works on the principle of capacitor charge and discharge, and due to its small size, it is easily mountable in surface-mount technology.
