Tantalum Capacitors

Tantalum capacitors are a type of electrolytic capacitor with polarized electrodes, typically consisting of tantalum cores (typically composed of tantalum powder particles) and electrolytic layers of dielectric, with a storage medium of either tantalum ions or activated carbon particles. They are widely used in a variety of electronic applications due to their miniaturization, low leakage current, and low capacity leakage rates. This makes them an ideal choice for use in electronic devices exposed to harsh environmental conditions, such as those found in industrial equipment and automobiles, as well as for applications that require high levels of stability and reliability.

M39003/09-0182 Application Field and Working Principle

M39003/09-0182 tantalum capacitors are a type of electrolytic capacitor with a working principle in which the capacitance of the components is based on the charge storage capacity of the tin-plated tantalum cores (typically composed of tantalum powder particles). The capacitance is dependent on the dielectric layer (more specifically, the tissue thickness), and the voltage requirements are determined by the size and geometry of the electrodes. This type of capacitor typically offers higher values of capacitance compared to other electrolytic types due to its larger surface area.

M39003/09-0182 tantalum capacitors are designed for a range of operation from -55˚C to 125˚C, and can be used in a number of applications such as RF/Microwave filters, AC/DC converters, automotive and industrial applications, switching power supplies and various audio applications. This type of capacitor is especially suitable for applications with higher temperatures and/or high signal frequency of up to 5GHz where their characteristics and small size are in great demand.

The working principle of the M39003/09-0182 tantalum capacitors is based on the model of dielectric charging and discharging, as an electric field is created when the voltage across the capacitor is changed. This electric field changes the concentration of the ions in the electrolyte and creates a charge within the capacitor. During the charging process, the ions move to the positive electrode forming an electric double layer, and the dielectric becomes polarized generating a charge on the electrode. During the discharging process, the ions move to the opposite electrode, releasing the electric double layer and dissipating the charge.

The high temperature performance of the M39003/09-0182 tantalum capacitors makes them highly reliable for application in automobile and industrial use. The enhanced stability and low leakage current are key factors for the reliability of such capacitors. In addition, the capacitors possess good noise immunity and excellent surge current characteristics, which make them ideal for applications that require high accuracy and stability.

The M39003/09-0182 tantalum capacitors are an important type of capacitor, available in many packages and sizes, suitable for various applications requiring high levels of stability and reliability. As they are smaller and require lower space than other types of capacitors, these tantalum capacitors are ideal for applications where space saving and miniaturization are important parameters.
