Tantalum capacitors, or Tantalum electrolytic capacitors, are an important passive electronic component that is widely used in everyday gadgets and industrial appliances. They are especially popular in power electronics, because they offer impressive performance at a fraction of the cost of other components. The T494A475K016AT is one of the most popular types of tantalum capacitors, and is renowned for its reliability, longevity, and moderate flow rate.

T494A475K016AT capacitors are also known as surface mount tantalum capacitors. This means they are compact and designed to be soldered directly onto printed circuit boards. They are very reliable, often lasting for more than 20,000 hours and retaining more than 85% of their original capacity. This makes them ideal for use in applications with long lifespans, such as those found in industrial control systems, medical electronics, and automotive systems.

The T494A475K016AT has a capacitance of 4.7 µF and a maximum rating of 25 volts. Its operating temperature range is -55°C to +125°C, making it suitable for a wide range of applications. The capacitor is also quite robust, with a low equivalent series resistance (ESR). This low ESR ensures that the capacitor stays within specifications during rapid transients and resists any outgassing, helping to maintain its reliability in high-temperature conditions.

In terms of the capacitor’s working principle, it is based on the principle of dielectric absorption. This is the ability of a material, such as a tantalum electrolyte, to store a charge when conjoined with another material, such as an insulator or conductor. For the T494A475K016AT, the dielectric used is tantalum pentoxide. This material has vastly superior performance qualities than other dielectrics and enables the capacitor to operate efficiently and reliably at high temperatures, making it a popular choice for industrial and military applications.

The T494A475K016AT is also quite popular in consumer electronics, as it can be used to store and release power in a variety of devices. It is often found in MP3 players, portable gaming consoles, and mobile phone circuitry. It is also used to provide power to backup storage components in laptops and other systems, ensuring that the system can stay online even during power disruptions.

In summary, the T494A475K016AT is a type of tantalum capacitor that is renowned for its reliability and longevity. It is a surface mount component that is often used in power electronics and consumer electronics. It is based on the dielectric absorption principle, and has superior performance due to its use of tantalum pentoxide as the dielectric material. It can withstand temperatures of up to 125°C and has a low equivalent series resistance, making it ideal for long-term operations.
