Working principle

The M39003/03-0336 is an axial-type tantalum capacitor, with a solid manganese dioxide electrolyte, and a single-ended termination. It is based on the principle of capacitance, which is the ability of a capacitor to store electrical energy in an electric field. The M39003/03-0336 capacitor consists of two metal electrodes, separated by an insulating material called a dielectric. When a voltage is applied to the capacitor, an electric field is generated between the two electrodes. The electric field stores energy while electric current flows through the capacitor.

The two electrodes of the M39003/03-0336 capacitor are made up of a tantalum core and a manganese dioxide layer. The tantalum core acts as the anode and is made from high purity tantalum powder. The manganese dioxide layer acts as the cathode, and is formed in the part by chemical deposition. The dielectric layer between the two electrodes is composed of solid manganese dioxide, which has excellent electrical insulation properties.

The M39003/03-0336 capacitor is designed with a termination system that provides ESD protection and a protective guard ring to prevent voltage variations. The protective guard ring is connected to the anode and cathode of each capacitor, and reduces voltage variations that can cause leakage and damage. This termination system provides the capacitor with excellent temperature, humidity and electrical-overstress (EOS) protection.
