It has an extended operating temperature range from -40 °C to +85 °C and a capacitance range from 0.0022F-2200F. Some other salient features include a long lifetime of up to 3000 hours, high ripple current withstanding capability, low impedance and excellent solderability. With regard to the construction (mechanical dimensions) of the SMQ250VS471M25X30T2, it has a case material of plastic PEI and an outer sleeve of polypropylene. The capacitor dimensions speak for itself in terms of robustness and while setting the gold standards for Aluminum Electrolytic Capacitors.

The SMQ250VS471M25X30T2 works on the principles of electrolysis, where two different metals, when placed immersed in a conductive liquid called an electrolyte, will generate a potential difference across their surfaces. In the case of this capacitor, two aluminum foils are sandwiched with non-conductive and dielectric materials and are used as electrodes. The electrolyte inside is usually a liquid representation of sulfuric acid or any other alkali metals, such as potassium hydroxide, sodium hydroxide and so on. Once the potential difference is generated, Nitrogen-based Oxide is formed on the Aluminum-sheets, which acts as an insulator. The formed film further helps to store energy, hence forming a capacitor.
