Tantalum capacitors are widely used in applications from consumer to aerospace and defense. They are designed and manufactured for high reliability and extreme temperature operation. The T491A105K025AT7622 is one such part of the tantalum capacitor family. This article will provide an overview of the applications and working principles of the T491A105K025AT7622.

The T491A105K025AT7622 is a surface-mounted, axial leaded, molded chip tantalum capacitor with a capacitance of 25 μF. It has an operating temperature range of -55°C to +125°C, and a voltage rating of 10 VDC. It is designed for use in high temperature, high reliability applications such as automotive systems, down-hole oil and gas rigs, military radios, and aerospace systems.

T491A105K025AT7622 tantalum capacitors are used in high temperature, stable power conversion and regulation. In these applications, the capacitor maintains voltage levels and ensures a steady DC power supply over a specified temperature range. It can provide power supply regulation and filtering in harsh environments.

The T491A105K025AT7622 utilizes a tantalum oxide cathode, which provides superior capacitance with a stable dielectric constant over temperature. Its oxide coating ensures long-term stability and is rated up to 6,000 hours at 85°C. The capacitor’s anode is constructed with a bi-layer nickel and tin contact, which allows for improved solderability. The capacitor exhibits a low ESR and low DF value for reliable operation.

In addition to its application in high temperature, stable power conversion and regulation, the T491A105K025AT7622 has many other applications. It can be used in decoupling and bypass circuits, signal filtering, and for high current pulse applications. It is also used for ripple suppression and in motor control devices and inductive circuits.

The T491A105K025AT7622 is also used in applications where miniaturization is necessary, such as in circuit boards that require space saving components. The capacitor is built to endure shock, vibration, and extreme temperatures, which makes it suitable for many military and aerospace applications. It can be used in portable instruments, such as altimeters and oxygen monitors, and in aircraft avionics.

The working principle of the T491A105K025AT7622 is the same as any other capacitor. The capacitor is composed of two plates, or electrodes, which are usually made of aluminum, tantalum, and other materials. A dielectric, or insulator material separating the two plates, provides the electrical resistance between them. When a voltage is applied to the capacitor, electrical charges accumulate on the two plates, and a voltage is stored until the circuit is completed.

The T491A105K025AT7622 is designed for high temperature and reliable operation, and is suitable for many temperature and reliability-critical applications. Its oxide cathode and bi-layer nickel and tin anode provide an exceptional level of performance at high temperatures. Its low ESR and low DF values also make it a reliable choice for power conversion and regulation. Its many features and applications make the T491A105K025AT7622 a great option for many mission-critical designs.
