Introduction

Tantalum capacitors are one of the most widely used electrolytic capacitors available in the market today. They are commonly used in consumer electronics and other electrical equipment due to their superior properties. The capacitor comes in two varieties — solid tantalum and polymer. The TAJE476K035HNJ is a solidly-constructed, low-ESR (Equivalent Series Resistance) tantalum capacitor that is most often used as a filter capacitor in power supplies, due to its low ESR and high current capability.

Construction

The standard construction of the TAJE476K035HNJ is a solid tantalum body, with a anode and cathode connected internally by a metal terminal and lead wire. The solid body contains a tantalum metal oxide powder, which is the dielectric material. The anode and cathode are separated by a metal oxide, usually tantalum oxide. A layer of metal oxide is also applied on the exterior of the body, which creates a semi-permeable barrier, preventing direct contact between the electrolyte solution and the dielectric material.

Properties

The TAJE476K035HNJ has several beneficial properties that make it suitable for a variety of applications. Its low ESR and high current capability make it ideal for power supplies while its low leakage current and high frequency performance make it suitable for high frequency switching applications. Additionally, the extremely compact size and light weight of the capacitor makes it well-suited for use in portable electronics. Lastly, its superior temperature characteristics make it highly reliable and durable, with a long life expectancy.

Working Principle

The TAJE476K035HNJ works on the principle of electrochemical capacitance. It is composed of two metallic plates, which are separated by a semi-permeable barrier. The capacitor stores energy in the form of electrostatic field created by the two plates and their insulating layer. When a voltage is applied, electrons are pushed and pulled across the plates and the dielectric medium, creating an electrical current. This current is regulated by the ESR (Equivalent Series Resistance) of the capacitor, which is proportional to the capacitance and affects the frequency response of the capacitor.

Application Fields

The TAJE476K035HNJ can be used in a variety of applications, including power supplies, high frequency switching, portable electronics, and more. Because of its small size and high current capability, it is often used in power supplies as a filter capacitor. It is also well-suited for high frequency switching applications due to its low ESR and high frequency performance, and its high temperature characteristics make it ideal for use in portable electronics.

Conclusion

The TAJE476K035HNJ is a solid tantalum capacitor that is suitable for a variety of applications. It has a low ESR and high current capability, making it well-suited for use in power supplies, and its low leakage current and high frequency performance make it ideal for high frequency switching. Additionally, its compact size and light weight make it highly suitable for use in portable electronics, and its superior temperature characteristics make it highly reliable and durable.
