The M39003/01-5512 is most commonly used in power conditioning and regulation applications. It is a popular choice for power supplies, switching power supplies, and lithium battery protection circuits. The low equivalent series resistance and high capacitance values make the M39003/01-5512 an ideal choice for these types of applications. The capacitor can also be used in filtering circuits to reduce noise, AC ripple, and transient signals.

M39003/01-5512 Operating Principles

The M39003/01-5512 is a polarized tantalum capacitor with a metallic anode, a porous cathode, and a dielectric separating the two. A tantalum capacitor works through the process of electrostatic coupling. The positive voltage on the anode attracts the electrons on the cathode side towards it, which builds up a potential difference due to the resistance of the dielectric. As a result, a charge (capacitance) begins to accumulate between the two sides. The capacitance of the M39003/01-5512 is determined by the size and shape of the anode/cathode electrodes, as well as the dielectric material used in between them. The higher the surface area of the anode/cathode electrodes, the higher the capacitance or charge. In addition, the choice of dielectric material affects the capacitance of a capacitor. Different dielectrics have different capacitance or charge-accumulation values.

M39003/01-5512 Construction & Features

The M39003/01-5512 is a surface-mountable tantalum capacitor with an axial lead. The capacitor case is made of epoxy-coated steel and is hermetically sealed.
