T491A105K025AT7280 are tantalum capacitors, which are a type of capacitor that is widely used in smartphones and other electronic devices. As one of the most commonly used capacitor types, these capacitors provide reliable electricity in a compact, efficient package.

T491A105K025AT7280 capacitors are a type of electrolytic capacitors, meaning they use an electrolyte as the dielectric material. This electrolyte is generally a mixture of organic solvents and anions, which provide high energy storage and dielectric breakdown strength. They are polarized and feature a minimum capacitance of 105µF, a maximum capacitance of 175µF, a rated voltage of 25V, a temperature range of -55°C to +125°C, and a capacitance tolerance of ±20%.

T491A105K025AT7280 capacitors are most commonly used in portable electronics, such as smartphones, notebooks, and other mobile devices. They are also used in the automotive, aviation, military, and telecommunications industries for supplying reliable power in low-voltage applications. Their excellent electrical stability, low ESR, and high ripple current performance make them suitable for high-frequency switching power supplies, high efficiency DC-DC converters, and motor control applications.

T491A105K025AT7280 capacitors are typically constructed using molded case enclosures, epoxy resin sealing, and silver plating contact surfaces. These materials provide excellent insulation and robust protection against electrical and mechanical interference. Additionally, these capacitors are constructed with a high Q factor, which allows them to retain their capacitance value over a wide range of frequencies.

T491A105K025AT7280 capacitors work by storing an electrical charge on two conducting surfaces separated by an insulating layer. When a voltage difference is applied across the capacitor, an electrical field is generated and electrons accumulate on the positive electrode, creating a charge imbalance. This charge imbalance creates an electric field in the dielectric material, allowing electrical energy to be stored. The amount of energy stored is proportional to the capacitance value, voltage, and frequency of the applied signal.

In summary, T491A105K025AT7280 capacitors offer reliable electricity in a compact, efficient package. They are most commonly used in portable electronic devices and are also suitable for a variety of other applications. Thanks to their high Q factor and stable performance, these capacitors are popular for providing reliable power in low-voltage applications.
