Tantalum - Polymer Capacitors are an advanced type of chip capacitors that combine both tantalum and polymer materials. These capacitors offer excellent electrical performance and high reliability in extreme environmental conditions. The 4TPE470MIL is a specific type of Tantalum - Polymer Capacitor from Vishay Dale. In this article, we will discuss the application field and working principle of the 4TPE470MIL.

Application Field of 4TPE470MIL

The 4TPE470MIL is ideally suited for high frequency, low voltage applications. It is commonly used in applications such as DC/DC converters, where voltage regulation is a key concern. Additionally, the 4TPE470MIL is often selected for applications where the temperature range is between -55 and +105 degrees Celsius. Such applications include automotive, military and medical equipment.

The 4TPE470MIL offers a few key benefits over other tantalum capacitors. Firstly, its temperature range allows for wide operation in extreme environments. Secondly, it offers an extremely low ESR, meaning it is capable of storing a high amount of charge. Finally, its small form factor allows for easy integration into tight spaces.

Working Principle of 4TPE470MIL

The 4TPE470MIL has a rectangular, 2225-inch footprint. Inside, it consists of two layers of tantalum powder and one layer of polymer material. The tantalum powder acts as the dielectric material between the electrodes. The polymer material is a negative dielectric that reinforces the dielectric layer and reduces leakage.

When a voltage is applied to the terminals of the 4TPE470MIL, electrostatic attraction occurs between the electrodes and the opposite charges of the two layers. This creates an electrochemical layer called an “electrolytic layer”. This electrolytic layer prevents the passage of current. Consequently, the 4TPE470MIL acts as an electrical insulator and enables the storage of energy.

Conclusion

In conclusion, the 4TPE470MIL from Vishay Dale is a type of Tantalum - Polymer Capacitor that is ideally suited for high frequency and low voltage applications. It offers excellent electrical performance and high reliability due to its use of tantalum and polymer materials. Additionally, it has a temperature tolerance between -55 and +105°C, an extremely low ESR, and a small form factor. When a voltage is applied, an electrolytic layer is formed and energy is stored.
