M39003/03-0458H Working Principle

A tantalum capacitor consists of a tantalum wire anode and a manganese dioxide cathode. This capacitor does not use a porous separator as a dielectric, instead it uses the dielectric oxide layer formed when tantalum is anodized. The manganese dioxide electrolyte works together with the oxide layer to form a solid state dielectric on the surface of the anode. When the capacitor is charged, this solid state dielectric allows maximum charge storage in the smallest space. The capacitance of this capacitor is determined by the thickness of the oxide layer, which in turn is determined by the voltage at which anode and cathode are interconnected.

Most tantalum capacitors, including M39003/03-0458H, are non-polar, so when selecting them for use, it\'s not necessary to be aware of the polarity. The structure of world-class tantalum capacitors is designed in a way that it is self-healing. That means, when there is an overload, the oxide film acts as a fuse and releases the excess current.

M39003/03-0458H adopts temperature staking insulation technology, which ensures a very low internal resistance. Furthermore, it has considerably high ripple current capacity and excellent load life performance. Additionally, M39003/03-0458H is robust and reliable, and its frequency range is very wide. That being said, with its advanced features and exceptional performance, it is no surprise to see M39003/03-0458H being widely used in many different applications.
