Tantalum capacitors have become a popular choice for many electronic systems because of their high capacitance, low cost, small size, and long service life. The TM3D476K6R3CBA is a type of tantalum capacitor, and it has a wide range of applications due to its high performance and reliable characteristics. This article will discuss the application field and working principle of the TM3D476K6R3CBA.

What is a Tantalum Capacitor?

Tantalum capacitors are electrolytic capacitors that are made of a tantalum oxide film and a cathode material. They are characterized by their large capacitance values. These capacitors are commonly used in electrical power systems, automotive electronics, and military applications due to their high performance and reliability.

TM3D476K6R3CBA Application Field

The TM3D476K6R3CBA is an ultrahigh-capacitance Tantalum capacitor. It is able to supply currents up to 3A and offer high capacitance values. This particular tantalum capacitor model is widely used in automotive, industrial and telecom applications. It is preferred for its low ESR, low leakage current, and high reliability, even in extreme temperatures. As a result, it is often used in systems that need to have high capacitance, such as power supplies, filters, and audio amplifiers.

TM3D476K6R3CBA Working Principle

The working principle of this tantalum capacitor is based on a reverse polarity technology. This technology helps reduce leakage current and ESR and increase the capacitance values. The capacitor consists of a five-terminal core with an insulated layer of tantalum oxide between the terminals. The layers have a specific property, and when a reverse voltage is applied, the electrostatic energy is released which increases the capacitance significantly.

When the voltage across the capacitor’s terminals is below a certain limit, the electric field within the capacitor is reduced and capacitance decreases. This is known as the so-called “soak-off” effect. When the voltage surpasses the limit, the electric field intensifies and the capacitance increases. This phenomenon occurs due to the porous character of the tantalum oxide film.

Conclusion

The TM3D476K6R3CBA is a popular type of tantalum capacitor due to its high capacitance, low ESR, and long-term reliability. It is mainly used in automotive, industrial, and telecom applications. The capacitor works by using reverse polarity technology to reduce leakage current and increase capacitance, as well as reduce ESR. Thanks to its stability in extreme temperatures, it can be effectively used in a wide range of electronic systems.
