The MnO2 cathode technology provides reliable self-healing behavior, where localized dielectric faults are isolated by the conversion of MnO2 to insulating Mn2O3. The +\/-10% tolerance and low ESR make it suitable for precision filtering and decoupling in power supply and telecommunications applications. The solid tantalum construction ensures stable capacitance over the -55 to +125 degC operating range with no dry-out concerns associated with wet electrolytic capacitors.","working_principle":"The 293D series uses solid tantalum capacitor technology where a porous tantalum anode is formed with a thin Ta2O5 dielectric oxide layer, then coated with manganese dioxide (MnO2) as the solid electrolyte cathode. The self-healing mechanism operates when a localized fault in the dielectric creates a conductive path; the resulting current flow locally heats the MnO2, converting it to insulating Mn2O3 and isolating the fault. This provides inherent fault tolerance. The solid construction eliminates the electrolyte drying mechanism that limits the life of wet aluminum electrolytic capacitors. The 22 uF at 35 V rating is achieved through the high CV\/g characteristic of tantalum pentoxide dielectric.","pin_description":"
