Tantalum Capacitors

Tantalum capacitors are electrolytic capacitors that use a solid electrolyte to store electrical energy. As a form of energy storage device, they are typically used to store energy and act as a filter to reduce the amount of noise in a system. Tantalum capacitors are commonly used for a variety of applications, including power supplies, UPS systems, and audio/visual devices. They can also be used for long-term energy storage.

The TAJW476K006RNJ capacitor is a standard tantalum capacitor component that is rated for a maximum operating voltage of 6.3 V and has a capacitance value of 47 μF. It is typically used in applications such as switching power supplies, EMI filters, decoupling and DC-to-DC converters.

Working Principle

In a tantalum capacitor, the electrical energy is stored in the form of an electric field created by the dielectric material – typically tantalum pentoxide – which acts as the insulator between the two conducting plates. The charging process begins when a voltage is applied to the plates, causing ions to be relocated in the dielectric. This is known as “capacitive charging” and the higher the voltage, the more ions are moved. As the ions are relocated, electrons are drawn to the negative plate, causing a build-up of negative charge there and a corresponding build-up of positive charge on the positive plate. This creates an electric field between the two plates, which is capable of storing energy.

The discharge process occurs when the capacitor is disconnected from its power source. The electric field collapses and the positive ions are drawn to the negative plate, and the electrons are drawn to the positive plate. The result is a steady decrease in the charge on both plates until equilibrium is reached. This process serves to reduce the amount of electrical noise in the system.

Application Field

The TAJW476K006RNJ capacitor is a standard component for applications requiring long-term energy storage and high-efficiency energy transfer. It is commonly used in switching power supplies, EMI filters, decoupling, and DC-to-DC converters. It is also used in automotive and industrial applications, as well as in medical equipment and instrumentation.

In switching power supplies, for instance, the TAJW476K006RNJ is used to store energy at times when the supply voltage drops, and then deliver this energy in bursts during peak loads, allowing for smooth power delivery. It is also used to filter out electrical noise from the power supply, reducing interference and improving system reliability.

In automotive circuitry and instrumentation, the TAJW476K006RNJ capacitor can be used to store and filter out electrical noise. It is also used to provide smooth power delivery, ensuring that the engine runs smoothly, and to reduce the risk of electrical failure.
