    Tantalum Capacitor is among one of the types of the 'Electrolytic capacitors'. This type of capacitor is Polarized in nature. In this capacitor a porous tantalum metal is used as Anode. It is further covered by the conductive layer known as Cathode. There is a layer of oxide present in it which acts as the Dielectric. It is known for the capability of generating higher amounts of

  • There is now an alternative to solid tantalum

    Tantalum is not the only capacitor technology in which polymer is being used to enhance stability. For frequencies approaching 1MHz, the 2mΩ ESR achieved by polymer aluminium capacitors can provide slightly higher capacitance retention without adding to design complexity. This reduced ESR does, however, have to be traded-off against the lower maximum capacitance of the polymer aluminium

  • Tantalum Capacitors: Advantages &

    What makes tantalum capacitors unique is the usage of tantalum for the anode of the device. This anode is set up as one chunk of material inside of the case, which is very different from the layering style used in MLCC capacitors where the material is sandwiched on itself and then capped on the ends. Using tantalum results in a very thin dielectric layer, resulting in a higher capacitance per
