Introduction

Tantalum capacitors are a type of electrical component. They are used to store electrical charge and help regulate the flow of current within a circuit. In common usage, they technically refer to capacitors with solid electrolyte that use tantalum metal plates as the electrodes. The model TR3A474M035C4000 specifically refers to a type of tantalum capacitor produced by Kemet. This paper will discuss the application field and working principle of TR3A474M035C4000.

Application Field

Tantalum capacitors of the TR3A474M035C4000 type are constructed with a solid double-anode tantalum case. They are extremely well-suited for many applications, such as micro-processing, audio-visual, automotive, and low frequency/high power requirements. The main advantage of TR3A474M035C4000 tantalum capacitors is that they have a very low equivalent series resistance (ESR) and equivalent series inductance (ESL) for their size. This means that the capacitors do not suffer from voltage spikes when used in high power circuits. Additionally, the capacitors have a low failure rate, unlike some other types of capacitors.

The device also has several advantageous features when it comes to its packaging. It has a hermetically sealed epoxy case that is both small and lightweight. It is also incredibly durable, meaning it can withstand long and hot operation times. This makes it a great choice for applications such as those listed above.

Working Principle

Tantalum capacitors work on the same principles as other types of capacitors. They store electric charge and discharge it when necessary. The main difference, however, is the construction of the capacitor. The TR3A474M035C4000 contains two electrodes: one that is formed by a double-enclosed tantalum case and the other is comprised of a solid tantalum dielectric. When current is passed through the capacitor, an electron is transferred from the double-enclosed tantalum case to the solid tantalum dielectric. This transfer creates an electrical charge, which is then stored in the capacitor.

When the capacitor is discharged, the charge slowly decreases, and the capacitor must be periodically recharged. The device is designed to have a low internal resistance, meaning that the capacitor can handle high frequency currents without suffering from voltage spikes. The capacitor is also designed to have a low equivalent series resistance, making it ideal for applications where high power is involved.

Conclusion

The TR3A474M035C4000 is a type of tantalum capacitor produced by Kemet that is suitable for micro-processing, audio-visual, low frequency/high power, and automotive applications. The main advantage of these capacitors is that they have low equivalent series resistance and equivalent series inductance, which makes them suitable for use in high power circuits. Additionally, they come packaged in a hermetically sealed epoxy that is both small and lightweight, meaning they can be used in devices with limited space and weight requirements. In short, the TR3A474M035C4000 is an ideal device for a variety of applications.
