Tantalum Capacitors

Tantalum capacitors, often referred to as tantalum electrolytic capacitors, are an extremely popular and versatile type of capacitor. The advantage of tantalum capacitors is that they come in a wide range of capacitances, ranging from a few microfarads to hundreds of microfarads, and they are extremely robust, stable, and reliable when compared to other types of capacitors. The typical lifetime of a tantalum capacitor is 30-50 times longer than that of an aluminum or film capacitor.

T86C155M035EBSS

The T86C155M035EBSS is an ultra-low ESR (Equivalent-Series-Resistance) tantalum capacitor designed for high-performance applications where robustness, long life, and low ESR are critical. The T86C155M035EBSS is the highest capacitance tantalum capacitor available from the T86C series, rated at 155uF with a voltage rating of 35V and ESR of 0.17 Ohms. The low ESR makes it ideal for high-frequency and ripple filtering applications in industrial, consumer, and automotive electronics.

Application Fields

T86C155M035EBSS capacitors are commonly used in a variety of infrastructure and consumer applications, including automotive systems, telecommunications, computer motherboards, power supplies, solar inverters, voltage regulators, and laptop chargers. The low ESR makes it ideal for filtering applications, such as ripple filtering and decoupling. It is also suitable for bulk storage applications such as power reserve in order to maintain stability in any application.

Working Principle

Tantalum capacitors are usually made from two plates of tantalum foil, known as electrodes, and separated by a dielectric layer made of an oxide of tantalum. The electrodes are connected to two electrodes of an external circuit, one being an anode and the other being a cathode. When voltage is applied across the capacitor, positive charges (holes) are attracted towards the anode and negative charges (electrons) move towards the cathode. These charges build up until they reach an equilibrium, creating a charge on the capacitor. The charge stored on the capacitor is equal to that of the applied voltage. This stored charge can then be used to provide energy to the external circuit.

Tantalum capacitors are widely used due to their small size, low price, wide capacitance range, long operational lifetime, and low impedance. They have become an invaluable part of today’s electronic components, as they allow designers to add features such as filtering, buffering, and energy storage to applications across multiple industries. The T86C155M035EBSS is a strong example of how this type of capacitor can be used in high-performance applications.
