Working Principle

ELXM421VSN680MP30S is a kind of polarized aluminum electrolytic capacitor. This kind of capacitor consists of two electrodes, an anode and a cathode, separated by an electrolyte. The electrolyte breaks down in the presence of an electric current, burning off any impurities and precipitating a thin layer of oxidation film on the anode. This oxide layer acts as a dielectric insulator, storing separation charge between the electrodes while blocking any electrons.

When the capacitor is charged, the electric field across the oxide layer increases. This causes the oxide layer to swell and become much thinner, enabling higher current densities to be transferred through it. The result is a greater capacitance than is found with other types of capacitors, with superior thermal capabilities. Additionally, due to the polarization effect, ELXSeries aluminum electrolytic capacitors can be easily charged and discharged quicker and with much lower losses than conventional capacitors.

When the ELXM421VSN680MP30S is connected in the circuit, the current between the two electrodes flows from the anode to the cathode, creating a capacitive electricity. As the voltage across the capacitor increases, the capacitance provided by the capacitor also increases, allowing more current to flow through it. ELXM421VSN680MP30S has a maximum voltage rating of 2V and a working temperature range of −55 to +105°C, making it extremely versatile.
