Aluminum electrolytic capacitors are common passive electrical components found in a wide variety of electronic circuits. They are available in both axial and radial leaded form in a variety of styles, ratings, and terminations. The specific physical characteristics of an aluminum electrolytic capacitor depend on the chosen construction and design. The DCMC484U016DC2D is one such part, a radial miniature capacitor made by Nichicon Corporation for their component series called “UVS”, concentrated effective capacitance version type D. The rated voltage for this capacitor is 16V and it has an allowable ripple current of 2800mArms.

Applications of this particular capacitor are predominantly in signal line, synchronous motor drive, and noise filter circuits due to its low equivalent series resistance (ESR) and low tangent of loss angle. Its features, which include long-term reliability and space-saving performance, and desirable characteristics for small load drive and signal line applications. This capacitors also have high heat resistance characteristics, which ensure it will perform consistently for a prolonged period of time in high temperature environments.

The working principle of this capacitor is a form of storage of electrical energy. It is based on the principle of electrolysis whereby an electric current is passed through an electrolyte (electrolytic solution) between two electrodes, an anode and a cathode. The anode and cathode get covered with a very thin layer of oxide due to the electrolysis and this thin layer stores the charge. When a voltage is applied to the terminals, current flows and the capacitor gets charged. This electrolytic capacitor consists of two thin aluminum foil plates separated by a paper or film insulator that is soaked in an electrolyte. When a voltage is applied to the capacitor, it increases the capacitance, enabling it to store charge.

The construction and design of the DCMC484U016DC2D is based on an electrolytic solution of pure aluminum anode foil, a paper or film separator, and an M(SCD) type black cathode. It has an operating temperature range of -55℃ to +125℃ and a rated ripple current of 1.2 A. Its capacitor life expectancy is 1000 hours at 25℃ and its surge current is 5 A. The manufacturers use a laser center welding process to secure the individual elements, which strengthens the construction and improves its reliability and repeatability. The capacitor is housed in a small 4x8x5mm plastic case and has a 6mm lead wire that is strong and flexible.

The DCMC484U016DC2D is a highly reliable miniaturized aluminum electrolytic capacitor suitable for a variety of applications, particularly small load drive and signal line applications. It is a miniature radial capacitor that has a long-term reliability and space-saving performance and has excellent heat resistance characteristics which ensure it will perform consistently for an extended period of time in high temperature environments. Its working principle is based on the principle of electrolysis, where an electric current is passed through an electrolyte between two electrodes, an anode and a cathode. The capacitor provides a high capacitance, allowing it to store charge efficiently and reliably.
