Tantalum capacitors are a type of electrolytic capacitor that utilizes a tantalum powder core and an conductive electrolyte. These types of capacitors are highly stable, have extremely high capacitance values, and have a very low equivalent series resistance (ESR). As a result, they are used in many applications from power supplies to audio amplifiers.

The 13008-042KESA/HR application field is a capacitor designed for use in high-reliability applications such as aerospace, defense, medical, and other applications where high reliability and long life are required. It is also suitable for use in high-temperature environments. This capacitor has a rated capacitance of 4.2 μF, a maximum voltage of 6.3 Volts, and a working temperature range of -55°C to 150°C.

To understand the working principle of the 13008-042KESA/HR, we need to understand how tantalum capacitors work in general. As mentioned above, tantalum capacitors use a tantalum metal core and conductive electrolyte as the dielectric. The electrolyte acts as an insulator, allowing electrons to pass through the metal core without causing electrical leakage. When a voltage is applied across the capacitor, a current is created which causes a build-up of electrical charge, or capacitance, that is stored in the capacitor and can be used for power applications.

The key to the success of a tantalum capacitor is its ability to maintain high levels of capacitance values even at very low levels of applied voltage. This is due to the ability of the electrolyte to retain its insulating properties even at low voltage levels. Also, because the electrolyte has a high dielectric constant, it has a higher capacitance value than other types of capacitors. This enables the capacitor to store more charge at any given voltage.

The 13008-042KESA/HR has been designed to be highly reliable and have a long life span, even in high-temperature environments. This is because the electrolyte used in these types of capacitors has a higher thermal stability than other types of capacitors. Also, this capacitor has a low ESR, which helps to reduce noise and reduce power losses.

Overall, the 13008-042KESA/HR is a very reliable and versatile tantalum capacitor, designed for use in high-reliability applications. The capacitor is able to retain its capacitance values at very low levels of applied voltage, is highly thermally stable, and has a very low ESR. Additionally, it has a long life span and is suitable for use in high temperature environments. All of these features make this capacitor a great choice for applications such as aerospace, defense, medical, and any other that require high reliability and long life.
