M39003/03-0343/HSD

Tantalum capacitors are electrolytic capacitors with a tantalum anode and a ruthenium oxide cathode. The anode consists of a tantalum pentoxide (Ta2O5) layer which acts as an insulating dielectric and electrolyte. The anode and cathode are separated by a tantalum membrane, which acts as a conductive medium that allows electricity to pass through. The edges of the tantalum anode and cathode are sealed by an epoxy compound, which prevents the electrolyte from seeping out and allows the capacitor to handle higher voltages. The M39003/03-0343/HSD is a radial-leaded, through-hole tantalum capacitor, rated for operation from -55 to +85 C° and up to 10 volts. It is available in a variety of sizes, ranging from 2.2 to 25mm.

The working principle of a tantalum capacitor is the same as a traditional electrolytic capacitor. It stores electrical charge within the capacitor by accumulating electrons on the anode, which attracts a layer of ions in the electrolyte towards the anode. These positive ions form a layer of charge between the capacitor plates, thus forming an electrical circuit. The capacitance of the capacitor is determined by the amount of charge stored between the two plates, the distance between the plates, and the dielectric constant of the anode material.

Tantalum capacitors find vast application in many areas due to their small size, high capacitance and low cost. They are used in a wide range of electronic designs, including switch-mode power supplies, low-noise amplifiers, and RC filters. The M39003/03-0343/HSD series is perfect for use in medical and military systems, due to its extra-robust construction and stability over a very wide operating temperature range.

In summary, tantalum capacitors offer several benefits and advantages over other types of capacitors, including excellent electrical characteristics, long service life, and small size. The M39003/03-0343/HSD series of radial-leaded, through-hole tantalum capacitors are a reliable and cost-effective choice for many electronic designs, offering excellent performance and reliability in a wide range of applications.
