Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are energy storage elements that use an electrolyte and a porous, electrically conductive material to store energy electrostatically. Capacitors come in a wide variety of sizes and shapes and have many applications. The MAL203134681E3 capacitor is a non-solid electrolytic type of capacitor well-suited for high-frequency applications and can handle large charge-discharge currents.

MAL203134681E3 Application Field

The MAL203134681E3 capacitor is a general purpose aluminum electrolytic capacitor. It is a snap-in version with radial leaded pins/leads and a cylindrical case. The maximum operating temperature of the capacitor is 105°C. It has a maximum voltage rating of 400V DC and a capacitance range from 33µF to 470µF. This type of capacitor is suited for output filtering, high-current filtering, and circuit damping applications in a wide range of electronic equipment.

MAL203134681E3 Working Principle

The aluminum electrolytic capacitor is made up of two aluminum foil electrodes that are separated by a thin and porous oxide layer. This oxide layer functions as an electrical insulator between the two metal electrodes. When a voltage is applied across the capacitor, the oxide layer is weakened and current is able to flow from one electrode to the other. This current flow forms a temporary energy storage at the nodes of the capacitor.

The MAL203134681E3 capacitor is a non-solid-electrolytic capacitor, meaning that it stores energy on two layers of foil separated by a relatively large space, rather than using a solid electrolyte material, like a polymer or oil. This design makes them suitable for higher temperature operation, as well as faster charge/discharge times and higher capacitance values.

The capacitance of the MAL203134681E3 capacitor is determined by the area of the electrodes, the dielectric constant of the oxide in-between them, and the thickness of the oxide layer. The amount of current that can be stored in the capacitor depends on the operating temperature and the ripple current rating of the capacitor. The typical life-span of the MAL203134681E3 capacitor is 2000 hours when operated at 105°C.

Conclusion

In summary, the MAL203134681E3 is an aluminum electrolytic capacitor that is ideal for high-frequency applications due to its high capacitance values and faster charge/discharge times.
