Tantalum capacitors are electronic components that allow current to pass through a metal oxide insulator. They are used for a variety of applications, including in high-frequency circuits and pulse power supplies. The T491B335K016AH is one such type of tantalum capacitor. It offers high capacitance and voltage ratings, making it suitable for applications with demanding power requirements. This article will discuss the application field and working principle of the T491B335K016AH.

The T491B335K016AH is a general-purpose, radial-lead tantalum capacitor. It is intended for use in applications with relatively stable operating voltages and currents, such as in non-critical AC line filtering and driver circuits. The capacitor offers a voltage rating of 16 volts and a temperature range of -40 to +85 degrees Celsius. Its capacitance rating is 335 microfarads, making it suitable for a wide array of low power applications. The capacitor is available in a range of sizes, from a diameter of 5.0mm to 10.3mm, depending on the capacitance rating.

The T491B335K016AH works on the principle of electrochemical charging. The capacitor\'s metal oxide dielectric material is oxidized, which creates a charge. An electric field is applied to the assembly and the polarity of the field interacts with the charge on the dielectric material to store electrical energy. As the voltage across the capacitor increases, the amount of charge stored in it also increases, resulting in capacitive charging. This is why the T491B335K016AH offers high capacitance ratings.

When the electrical energy stored in the capacitor starts to discharge, ions in the electrolyte move through the dielectric. This movement of ions produces an equal current out of both leads of the capacitor, creating a discharge. The greater the voltage applied to the capacitor, the faster the discharge will be. This is why the capacitor needs a higher voltage rating when it is used in applications that require high currents. Additionally, the capacitor\'s working temperature range of -40 to +85 degrees Celsius makes it suitable for voltage-stabilizing circuits that require temperature stability.

The T491B335K016AH is also highly reliable and can handle large inrush currents. It can operate in any direction and has a maximum pulse voltage rating of 35 volts, making it suitable for a variety of high power applications such as power amplifiers and power converters. Additionally, it is available in a variety of lead types, from straight leads to J-leads, which makes it easier to install.

In conclusion, the T491B335K016AH is a general-purpose, radial-lead tantalum capacitor. It is suitable for applications with relatively stable operating voltages and currents, such as in non-critical AC line filtering and driver circuits. Its high capacitance and voltage ratings, along with its reliable pulse and inrush current handling, make it ideal for a variety of applications in fields such as power amplifiers and voltage-stabilizing circuits. The capacitor operates on the principle of electrochemical charging, using its metal oxide dielectric material to store electrical energy.
