Tantalum Capacitors

Tantalum capacitors are capacitors that are made from the element tantalum. Tantalum capacitors are used in a wide range of circuits, from analog audio circuit to digital board applications. Primarily, they are used to store energy in a circuit and to filter out unwanted electrical signals. Tantalum capacitors are available in a variety of forms, sizes, and options, making them suitable for many different applications. Understanding the fundamentals of how a tantalum capacitor works is essential for selecting the best component for a particular application.

TRJA475M016SRJ Application Field and Working Principle

The TRJA475M016SRJ is a low-profile, surface-mount tantalum polymer capacitor. It is a very cost-effective device, with a rated capacitance of 4.7µF, rated voltage of 16V, and maximum ripple current of 1.1A. It is typically used for decoupling and noise suppression, and as a bypass capacitor in power applications. The TRJA475M016SRJ has a wide operating temperature range from -55ºC to +105ºC, making it suitable for a wide range of applications.

The working principle of a tantalum capacitor is based on the simple fact that when two conducting plates are separated by a dielectric material, an electric field is created. When a voltage is applied to the capacitor, the electric field causes electrons to flow through the dielectric material, creating a charge. The capacitance of the capacitor is determined by the amount of charge stored in the capacitor, which is in turn determined by the physical characteristics of the plates and dielectric.

Tantalum capacitors offer a number of advantages over traditional capacitor technologies, such as electrolytic and ceramic capacitors. They are typically very low in cost and have an extended life, due to their high volumetric efficiency, which is determined by the ratio of capacitance to volume. They have excellent temperature stability, a low equivalent series resistance, and a very low equivalent series inductance. They also have a very high self-healing capability, meaning that if a capacitor is overstressed, the dielectric will repair itself, restoring the original capacitance.

The TRJA475M016SRJ is a very popular and reliable tantalum capacitor, and is widely used in a range of applications. With its low-profile design and wide temperature rating, it is an excellent choice for decoupling and noise suppression applications, as well as for bypassing applications in power circuits.
