T491A225K020AH4162

T491A225K020AH4162 is a type of tantalum capacitor, also known as solid electrolytic capacitor, which can be identified by its low profile, high capacitance, high impedance and good temperature characteristics, as well as its specific characteristic that it comes in “can” or “dial” style. Specifically, the T491A225K020AH4162 is a solid electrolytic capacitor that has a polarity marking and a negative lead. In its construction, it is a tantalum electrolytic capacitor that uses an anode formed from a sintered tantalum particle and an anode electrolyte. The anode material forms a strong, impervious barrier and highly stable negative dielectric oxide layer. The oxide layer, in turn, provides for extremely high amount of energy storage in the same volume as a ceramic capacitor. The cathode of a tantalum capacitor is typically made from solid manganese dioxide.

The T491A225K020AH4162 is primarily used for applications like cost-effective filtering and power conversion solutions. Moreover, it narrowly surpasses the reliability and performance of other aluminum electrolytic capacitors, which makes it the choice of the industry for power electronics applications. In these applications, it benefits from its lower profile, higher capacitance, higher impedance, good temperature characteristics, and wide-ranging input voltage ranges. It is also useful in other applications like pulsed power conversion systems, as its superior long-term reliability and exceptional thermal performance make it ideal for long term, mission-critical applications.

T491A225K020AH4162 works mainly on the principles of electrostatics. When two surfaces are separated by an insulator or a dielectric, they form the basis of the charging mechanism that can be used to store electric charges. Since a polar dielectric always consists of two conductive surfaces, capacitors become extremely useful in this process. In an electrolytic capacitor, an anode oxidizes the anode electrolyte, forming a strong and impervious barrier layer, and provides extremely high amount of energy storage in a small volume. The anode dielectric layer also greatly improves the performance of the capacitor.

Overall, the T491A225K020AH4162 has a wide range of applications and is considered to be ideal for long-term, mission-critical applications. Its superior long-term reliability, exceptional thermal performance and high capacitance make it a preferred choice for cost-effective filtering and power conversion solutions. Moreover, because of its low profile, it is also suitable for use in volume-limited applications, such as pulsed power conversion systems. With its unique features and benefits, it can be used in a variety of applications, from automotive to medical.
