T491A225M025AT Datasheet/PDFTantalum Capacitors
Tantalum capacitors are one type of non-polarized electrolytic capacitors, which are characterized by a large capacitance per unit volume. The T491A225M025AT is a type of tantalum capacitor that is used in mission-critical applications where other capacitors may not offer acceptable performance. It consists of a tantalum anode, a foam core and manganese dioxide cathode material, and a dielectric layer of tantalum pentoxide. Compared to other electrolytic capacitors, the T491A225M025AT offers a higher capacitance density and a longer operational life.
The working principle of the T491A225M025AT can be explained as follows: The cathode of the capacitor is charged with a negative voltage, which induces a positive voltage at the anode. An electric field is created between the two electrodes, which results in a charge separation and a high potential difference between the electrodes. This creates an electric field across the dielectric layer, which generates an electric charge. This charge is stored in the capacitor and can be discharged when needed.
Tantalum capacitors are a reliable and efficient way to store and release electrical energy. The T491A225M025AT is a popular choice for a variety of applications, such as power supplies, where it can be used to smooth current flow, as well as in filters, amplifiers, computers, and other types of electronic devices. Its high capacitance per unit volume makes it an excellent choice for applications that require large amounts of energy storage. It is also known for its high reliability and long-term performance.
Tantalum capacitors have some advantages over other types of capacitors. They are more reliable and efficient, as well as more compact and lightweight. The small size makes them suitable for use in high-density circuit boards, and hybrid modules. They also have a low self-discharge rate and can operate over a wide temperature range, making them ideal for use in military and industrial applications.
In conclusion, the T491A225M025AT is a popular choice for mission-critical applications, offering high reliability and long-term performance. It offers a high capacitance density and a wide temperature range, making it suitable for a variety of applications. It is also a reliable and efficient way to store and release electrical energy.
