Working Principle

A Tantalum Capacitor works by storing electrical energy in a non-conductive dielectric layer between two conductive plates. When a voltage is applied between these two plates, electrostatic fields are generated that create an electrostatic potential in the dielectric. The electric field prevents current from flowing between the plates. The dielectric layer determines the capacitance or amount of energy stored in the capacitor, which is measured in Farads.

The M39003/01-7005/HSD uses a tantalum pentoxide (Ta2O5) dielectric. Tantalum pentoxide has the highest dielectric constant among all known dielectric materials, which leads to higher capacitance in a very small package. Furthermore, tantalum pentoxide has high thermal stability, which is why it is the preferred material for high-temperature applications.

Tantalum capacitors also offer a number of other advantages. They have a low equivalent series resistance (ESR) which helps to minimize power losses at high frequencies. They also have a low leakage current, meaning they do not require frequent replacement due to gradual charge decay. Additionally, they have excellent temperature stability and are not affected by extreme changes in temperature.

The M39003/01-7005/HSD is a reliable and high-performance capacitor which is designed to provide superior performance in both normal and high-temperature environments. It is an ideal choice for automotive, space, military, and industrial applications that require reliable and stable power supplies.
