Tantalum - Polymer CapacitorsT523W686M016APE100 is a tantalum-polymer capacitor, a type of electrolytic capacitor which combines the advantages of other electrolytic capacitors and super capacitors. Being more rugged, lower profile, and offering higher capacitance, they are suitable applications where space and stability are critical, while achieving the performance of electrolytic capacitors. Tantalum-polymer capacitors are formed from nanoparticles or nanowires of tantalum deposited directly onto a porous substrate, resulting in a much higher power density than older types of capacitors. These nanoparticles act as insulator-electrolyte-semiconductor structures for overall ion storage and transport. The substrate is composed of a layer of polyethylene, with a polymer electrolyte, or dielectric, on top of it. This polymer electrolyte stores a large amount of ions in the structure, which can then be released when a current is applied to the structure. The ions are then repeatedly exchanged between the nanoparticles and the dielectric, and are ultimately converted into electrical energy. The main advantages of tantalum-polymer capacitors over other electrolytic capacitors are their high capacitance and stability. Tantalum-polymer capacitors can store more electrical energy per unit volume than other electrolytic capacitors, resulting in higher capacitance and higher maximum current. They also have better energy stability, meaning they can maintain a consistent voltage over time when subject to vibration, shock, and temperature changes. This makes them ideal for applications such as power supplies, audio amplifiers and battery management systems, which need to maintain a consistent output over unpredictable conditions. Tantalum-polymer capacitors are also well suited for applications requiring low ESR, such as power management applications like DC-DC converters. A low ESR allows for a high ripple current, which can be useful for high frequency switching applications. The low ESR and excellent voltage stability of a tantalum-polymer capacitor also make it a good choice for energy storage applications. In terms of cost, tantalum-polymer capacitors are more expensive than ceramic and other electrolytic capacitors. This is mainly due to the complexity of designing and constructing the structure. However, the higher performance, stability and reliability of these capacitors often make them worth the extra cost. Overall, tantalum-polymer capacitors offer a compelling solution for applications where space and stability are critical, while still achieving the performance of electrolytic capacitors. With their high capacitance, energy stability, and low ESR, these capacitors are suitable for applications such as power supplies, DC-DC converters, audio amplifiers, and energy storage.
