Working Principle of the M39003/03-3015H

The M39003/03-3015H utilises tantalum technology, which offers extremely low resistance in combination with the high voltages the capacitor is capable of handling. This combination makes the M39003/03-3015H ideal for power supply applications that require a high capacitance and low DC resistance. The capacitor sees an energy storage of an electrical field that is created by the surface of the tantalum metal and the electrolyte. This energy storage then provides the electrical potential that can be tapped and used when needed, such as symbolised in the capacitor.

The M39003/03-3015H is constructed using a combination of porous tantalum anode, conductive polymer cathode and liquid electrolyte. It can operate at temperatures up to 105 degrees Celsius, making it suitable for applications with extreme thermal or environmental conditions. The capacitor is also hermetically sealed, enabling it to withstand moisture and dust.

Advantages of the M39003/03-3015H

The main advantage of the M39003/03-3015H is its low ESR (equivalent series resistance) and high capacitance. This makes it suitable for use in power supply applications that require low DC resistance and high capacitance. Additionally, it also offers superior stability and reliability in comparison to other types of capacitors.

The M39003/03-3015H also provides excellent thermal properties, and is able to withstand temperatures up to 105 degrees Celsius. Furthermore, it is hermetically sealed, making it resistant to dust and moisture.

Disadvantages of the M39003/03-3015H
