Because of its very thin and relatively high permittivity dielectric layer, the tantalum capacitor distinguishes itself from other conventional and electrolytic capacitors in having high capacitance per volume (high volumetric efficiency) and lower weight. Tantalum is a conflict resource.
This oxide, tantalum pentoxide, has a dielectric constant of 26. The tantalum metal serves as the anode, and the cathode is usually made of a conductive material, often manganese dioxide in traditional tantalum capacitors. Another name for a wet tantalum capacitor is liquid tantalum capacitor or non-solid tantalum capacitor.
They have self-healing properties, allowing thinner dielectric oxide layer, and high capacitance per unit volume. Solid leaded tantalum capacitors: They have higher capacitance density than wet aluminium electrolytic capacitors or solid tantalum type. Higher electron conductivity makes them sensitive to voltage spikes or surge currents.
In solid tantalum electrolytic capacitors the heat generated by the ripple current influences the reliability of the capacitors. Exceeding the limit tends to result in catastrophic failures with shorts and burning components.
In data sheets of electrolytic capacitors, only the impedance magnitude |Z| is specified, and simply written as "Z". Regarding to the IEC/EN 60384-1 standard, the impedance values of tantalum electrolytic capacitors are measured and specified at 10 kHz or 100 kHz depending on the capacitance and voltage of the capacitor.
Tantalum capacitors are made by pressing the tantalum powder and forming it into a pellet through sintering. Tantalum capacitors are beneficial because they form an extremely thin dielectric, as little as 20 - 400 nm thick.
