Tantalum Capacitors – M39003/03-2065/HSD Application Field and Working Principle

A tantalum capacitor is an electrolytic capacitor that utilizes tantalum as an electrode. These capacitors are typically constructed with two anodes of powder tantalum which are sintered physically and with two layers of tantalum oxide as the dielectric layer. The anodes are soldered to the outside terminal of the capacitor for easy connection. This specific capacitor - the M39003/03-2065/HSD - is usually used in aerospace, defense, commercial, and industrial applications. It offers a high degree of capacitance stability and ripple current capability, long service life, as well as excellent temperature characteristics.

Working Principle

Tantalum capacitors, such as the M39003/03-2065/HSD, use a process known as anodic oxidation to form the oxide layer on the anode. This process involves creating an acidic solution, allowing the anode to soak in it for an extended period of time. During this process, the reaction between the metal and the acid causes charges to build up, which then cause the formation of the anode oxide. This oxidation process results in increased charge storage, leading to higher capacitance.

When a voltage is applied to the anode and the cathode, the oxide layer acts as a dielectric and prevents a direct current from flowing between the two electrodes. Instead, a current flows in from the anode, around the oxide layers, and exits through the cathode. As this process continues, an electric field is generated between the two electrodes, causing additional charges to build up in the oxide layer. This increases the capacitance of the capacitor, which can be used to store energy.
